[quote name='FinnDave' timestamp='1392799264' post='2372776'] I was obviously ahead of the times! I recently sold my Ashdown 410 (not bought in 1978!) and replaced it with a Barefaced 212, there is a world of difference between them. [/quote] Could just be that a 1 x 212 solution (or a 2/3 x 112 maybe) is the way to go. I mean if I can have a 25 kg. 212 performing like my current 115+210 I would be more than happy. Reason why I am being so anal about all this is, that the diversity of bass gear really sucks here. That means that I will likely buy my stuff from UK or DE. And since a bass cab is not exactly in the same league as sending a postcard, I would like to hit the bullseye on my first try .

[quote name='LukeFRC' timestamp='1392796281' post='2372740'] my point was more that there are a lot more variables to what a cab can produce than simply cone size and number. [/quote] I do agree... And I am certainly not intending to 'know better' or arguing for the arguments sake . Quite simply, I am trying to get wiser, and hopefully end up buying a nice cab or two (preferably the size of a matchbox, with APL and low end to spare ). Regards. Torben

[quote name='FinnDave' timestamp='1392743076' post='2372233'] I'd question your dates, I remember buying a 410 back in 1978, used it for bass exclusively for several years. [/quote] No rules without exceptions I guess... Still, looking at the 2 hand market it appears to me that alot of the cabs are products of their time, configurationwise. For instance you don't really see that many 2x12" configurations older than say 15 years. A funny side note on the 2x12"... A shop here in Copenhagen developed, in start 90's, what they thought to be the ultimate cab configuration. Advocating that the 2x12" configuration was by far the best compromise all things considered (size, weight, frequency spectrum). Mind you, this was before it became evidently popular to put tweeters in the cabs. They developed the cabs, using Beyma units which they seemingly modified a bit.

[quote name='LukeFRC' timestamp='1392742635' post='2372226'] efficiency... tuning... low end response... [/quote] Effiency: I agree that materials today are better than 30 years ago. But you sill need to displace some serious air in the lower register. Smaller unit = more movement = Higher average speed of the membrane = Hard work for the amp (?). Tuning: Dunno... I am not sure we know ALOT more about tuning today, compared to 30 years ago. But we may have become alot wiser on how we as humans percieve sound... Low end response: Requires movement of air... Alot of air. On the note (no pun intended) of tuning, you do have different options. Horn loading, transmissioin line bass reflex to name some of the well known ways of emphasizing low end respnse. But none of these principles are perfect.

TC heads tend to be quite reasonable on our local 2 hand market too 😊

Catchy headline... Eh ?! Following a discussion in another thread, I came to thinking: Been playing bass for 25 years (on and off), and as I am on the prowl for one or two cabs to complete my new setup, some thoughts came up... When I started out, 15" drive units were very very common, and the cabs were big as buildings. certain makers were beginning to put out 12" cabs for bass, but as I recall mainly for combos. A little later on it was combinations of drive units... 115+412 was very popular, and as time passed people even begang flattering the 115+410 combination, leaeding to the 410 fashion really taking off. I remember in the mid/late 90's many fellow bass players running 2x410 in their setup. Seemed like the more drive units the better !. Then the 210 and 212 sort of gained popularity... And after that even the 112 flavour. Looking at the second hand market today sort of reflects this change in fashion and taste. 610 and 810 cabs are selling at very very low prices, and are typically up for grabs for quite some time. This made me think a bit... What parameters are into play here ??. I can think of the following off hand: Fashion, plain and simple Technical development Supply & demand (This sort of goes with the above, as there is usually a 'sweet spot' decided by demand and research budgets) Portability (very important factor... Just look at smartphones and laptops !) Simplifying things alot, we are still dealing with pistons moving air... Meaning surface area is indeed a factor. You cannot defy the laws of physics here. In another thread there was a guy pointing out that more units (as a very general rule) equals more outpout pr. Watt. I think that was the philosophy back in the prime of 810 cabs... That wall of sound, nomatter what exotic detune you could think of. I decided to make a very simple chart (very very simple, but usefull)... [sharedmedia=core:attachments:155621] So from the calculations we see, that for instance 1x15" is only a little more than 2x10" which roughly equals 3x7" and so on. Interestingly the 4x10 is about 150% combined area of very very popular 212 combination, and as ultralight cabs go the only weigh app. 5 kg. more as I remember. This is the point where I need someone filling in the blanks. There many other (physical)parameters than just surface area that determines optimum performance... Voice coils for instance (length vs. diameter and more), given that a smaller unit has to work harder to output he energy in the lower register, than a larger unit. Anyone have some formulas explaining the relationship between the amount of air to be moved, compared to the stroke of a given membrane for starters ?. Regards. Torben

I will admit to not having 'been around' very much on the amp side of things, and that 15" statement is based purely on my own experience. Two 12" have more area over the units, and as such they should push some more air. My personal experience is however, that when turned up, the dual 12" runs out of breath faster than the 15". The only logical explanation I can find is, that there is some phase disturbance cancelling out the longer wavelengths when operationg more than 1 piston. But I have no, what so ever, proof to back that up. As a matter of fact, I am searching for a cab solutions these days, light, nimble and able to handle a solid low B when loud (as in LOUD !). Again, trying some different options it just seems that the bigger speaker gets more of that <40Hz. subsonic feeling out of the box. My plan with the 110 cab I own is not to use it in the prog band. At the moment I am operating my 115 Neogorm + 210 extension cab for that purpose. But I am planning on getting together a 110+112 EBS Neo combination for another band, playing at more civilized volumes .

Very recently bought a MarkBass MoMark 500 as an 'experiment amp'... It impressed so much that I have decided to jump into the Class D segment (with a different amp that should show up soon). Excited ??, Yes indeed I am .

I don't have much experience with single 12's, but after hearing what my EBS Neoline 110 is capable of on it's own, I have decided to go searching the second hand market for a similar 112 to partner with it. I am playing in a prog rock band, which requires alot of bottom end, and so far nothing short of a good 15" has been able to cope. However, in just about any 'normal' band I would consider a 112+110 combination to be more than adequate.

So... Still struggling to figure out what to do for gear. Actually ended up purchasing a Momark 500 today, mostly to play around with it and see what that whole light weight amp thing is all about. Went to the rehearsal room tonight to try it out, and experiment a bit with my rig, and my options. Hooked the Momark up to the 210 NeoLine EBS I have, and tested. First of all I must say that I am very very impressed with both the Momark and the smallish 210. Both handled my 5 string Dolphin quite good... Even at LOUD !!!. The 210 was elevated to just below earlevel, and that is really not adviceable in those conditions. Much much too bright !!... Very reflective concrete walls... Earbleeding !. Luckily I know from experience that they sound radically different under less extreme conditions. Impressed as I was with the size/volume ratio of the combination, it won't cut it as a practice rig. As I small side note, I also hooked up the Momark to my EBS Neoline 110... Not even close to cutting it for band practise, but the combination was jawdroppingly capable for it's size... I was impressed to put it mildly... Maybe a combination of the 110 being 8 Ohm, and the Momark being one of them lightweight amps... I don't know... But god damn impressive !!. To the point... A Neoline 115 just came up for sale localy, and as I actually like the 115+210 EBS combinatin boxwise, I am tempted to buying it as a 'base system'. However I am slightly concerned as to my options on the amp side with that rig... Seeming as most bass amps are mono-only constructions, they usually don't cope too well with 2x4 Ohm cabs on the output. What would my options be for amps that could handle the 115+210 combination ?... Dual mono constructionas are rare in the world of bass amps ??. Any pointers will be appreciated ! . If I decide to go the 'lightweight amp' route, I will need to settle for 1 or 2 8 Ohm boxes... Preferably something not overly bright sounding. Experimenting with the 210 today, I am doubtful that a 212 will be enough for rehearsal (yes, it is loud !!... Thank god for earplugs). So I am looking a bit on 410's on the used market. Very very tempted by the Epiphani UL410 for sale on BC, price is reasonable, but postage is quite steep. I have another more or less local option, which is a Markbass 104HF (Made in Italy). Any other options I should look out for ?. A bit of a longshot is... I will alomst certainly replace my Microbass with a Lehle Bassswitch DI. I could maybe use that to drive a dual mono poweramp of sorts, and go into the 210+115 ??. That should work... Right ?!. Regards. Torben

[quote name='gsgbass' timestamp='1392551879' post='2369892'] Check out the TC Electronic cabs, BC series. They have a 2X12, and a 2X10 that are 8 ohms. [/quote] Overheard som TC-stuff in a local shop yesterday. Didn't sound too bad IMHO. However, a band situation is ofcourse a completely different thing. TBH, I am just about at my wits end with my gear situation... Kind of frustrating !!.

[quote name='wateroftyne' timestamp='1392544790' post='2369790'] Absolutely. All credit to EBS - they seem to be a bit more realistic about ratings. [/quote] It seems so... Only thing that bothers me is, that their (excellent) cabs are pretty much all 4 Ohm. That rules out driving more than one of the damn things with a typical class D amp .

Looks nice, the TC + the Ampeg ! Risking repeating myself... I am very very doubtful about the actual power (or load handling to be precise) of the present Class D amplifiers. My only experience with this concept has been in my HiFi stereo system, where I had a 2x200 Watt poweramp at one point. That one damn near burned down at a New Year's party, driving a pair of power hungry speakers. The episode mentioned above goes years back, and I am sure that alot has happened on the Class D front since then... I am currently looking at the amp market, and very tempted to go for the Glockenklang Blue soul head. But the Class D thing does scare me off a bit... Particularly that most of the heads seemingly won't drive anything below 4 ohm (officially). This indicates to me, that even though they look powerful on paper, there could be some real world 'Ooomph' lacking somewhere. The weight of the things does appeal to me though .

[quote name='squeezer' timestamp='1392482870' post='2369292'] For starters, you can draw a lot more than 3kW from a 13A mains socket In the UK) so long as you don't do it for too long. A "13A" fuse won't blow at 2x the current rating (6kW) for a minimum of 10 seconds (maximum is it will never blow), at 3x current rating (9kW) blow time is between 0.3 seconds and 2 minutes -- yes, there's a pretty big tolerance here. [url="http://openenergymonitor.org/emon/sites/default/files/Circuit_Protection_Characteristic_Curves.png"]http://openenergymon...stic_Curves.png[/url] And most bass players don't play continuous sinewaves -- even for heavily compressed/limited bass the average power is less than a quarter of the maximum. Put these together and you can safely use an 8kW class-D amp (playing bass guitar, not sinewaves) on a single 13A mains socket, and 6kW on a 10A socket. [/quote] Ok, part of the explanation there I guess (for UK at least). I realize that with 'enough' capacitators you can theoretically wrink out thousands of watts... But then we would sort of have to state the amps performane in Farad instead of watts ??. Another thing is, that a great deal of poweramps out there are not meant for electric bass. They are meant for PA, and there you can easily have a good, heavy, even load on the amp... And ask it to pull of blasts of peak power on top !. Personally ofcourse (for my bass rig) I can do with alot less than 2000 Watts... I am just a bit reluctant to the method of measurement used. I always found that a good RMS measurement is the best indicator, and 2x2000 Watts RMS would definately blow the fuses where I am rehearsing

[quote name='squeezer' timestamp='1391867897' post='2362139'] As Bill F. said you can make a good or bad amp (with a good or bad power supply) of any class. Designing good class-D amps is more difficult but can be done, the other side of this is that because it's "easy" to do "high-power" class-D amps with SMPS (small, light) lots of manufacturers cut corners and make bad ones with insufficient energy storage or power reserve, and this applies just as much to bass amps (maybe more) as PA power amps. But some do it properly -- if you want *really* loud punchy bass but think class D amps can't deliver it, you could try connecting one of these up to your pre-amp and cabinet(s)... ;-) [url="http://www.pknc.com/3phase_eng.html"]http://www.pknc.com/3phase_eng.html[/url] [/quote] I am on the prowl for a new amp setup, and I have considered a pre/power solution with a class D powerunit. One thing that bothers me a little, looking at those figures is... For instance: Power output in ??? Ohm : 2x2000 Watts. Ok... Here normal wall outlets are app. 230 Volts. Normal household fuses are app. 10 Ampere. Now that makes the maximum powerdraw from one wall outlet 230x10 = app. 230 Watts. If (Theoretically) the amp had no heat dissapation = 100% efficiency (unlikely, even for class D), and there was nothing in the amp at all consuming any power... The maximum 'real world' power the amplifier could deliver, would be 2300 Watts. Or ???

[quote name='chris_b' timestamp='1392115945' post='2364768'] TKS, Hevos, Vanderkley or another EBS. You're spoilt for choice over there. Do you have an opportunity to hear any of these your area? I'd look at Bergantino cabs and also talk to Alex at Barefaced. [/quote] In this particular part of 'the mainland' it would seem that everyone is a guitarplayer. Bass gear just isn't moved at all, it seems. Brandwise my options are pretty much Mesa/EBS/Orange/TC(ofcourse)/and some Fender stuff etc. if I wan't to be able to go try before buying. Not that there is necessarily anything wrong with these brands though Regards. Torben

First: Thanks again for the comments, I am changing basses much much more often than amps - So I feel quite noob'ish in these waters. Technically (I will try to keep it short)... It may sound weird, but the rehearsal room is actually the shape of a dome, and with massive concrete 'walls'. Actually it's an old bunker built during the cold war... Alot of those old bunkers now serve as rehearsal rooms in Copenhagen . I am mainly having issues with two things: One is (a classic, I think) that I am having alot of trouble hearing myself... Particularly when it all gets a bit loud. I know that the main cause of this is, that I am standing quite close to my gear. Other members claim that I am very very present where they stand. What I'm figuring is, that if I seperate my stuff, I could move the speakers away (and in front) of me, and still fiddle with my sound, being close to my amp. Another issue (but a bit related) is, that I tend to get into the singers mic.. I try really hard to adjust my low end output, but given the shape of the room, and my placement there, it can't be cured completely. Again I figure, that a separated setup would give me more choices. At times I have also given it some thought, to go for something a bit 'lighter' cab wise. Thing is just that I really don't want to loose too much bottom end punch. Regarding my Microbass... Well... It's a nice device as such. I use it mainly as an A/B switch and the preamp part of it is a bit unused (except for levelling out the outputs of the basses). I have this idea, that I would like an amp that supports dual inputs, thereby getting a more 'clean and uncolored' sound. I really prefer a straight up clean bass sound, and every effect I use have a sound degrating effect (maybe it's subjective... But still...). Part of the plan is to introduce a Lehle D.Loop for the effects, and have a nice celan-as-possible signal into a very nice head. How would you describe the differences in sound of TC compared to say... Glock... Or EBS ?. Just came across another option of configuration (keeping an eye on my local 'gumtree'). I could move my 115 Combo, and get a 110 EBS Neo cab to supply my 210... Thereby having a 310 configuration total. Not sure how (if ?!) that would work though... Regards Torben

Thanks alot for your opinion... It is much appreciated !. Describing sound character in words is always hard, but soft is definately not what I need... That being said, I do think my EBS cabs may be a tad too 'Hi-Fi sounding', that being having a somewhat top end focus. I have had the tweeter turned all the way down on the from day one. Mid to bottom is however really tight, even when pushed a bit... Which is something I appreciate alot !!. I have more or less decided to take the plunge on the Glock head. So in time I will need some cabs to go with it. I will try to look out out for some 2x212 solution I think... Or maybe 210+212 combination. Regards Torben

So, I caught the GAS bug again... Currently I am running an EBS Neogorm 115 combo, with a Neoline 210 extension cab. However, I got this idea that I would like to separate my setup into a head + one or two cabs... My experience with amps/cabs is fairly limited... The EBS rig is serving me fine as such, but I would like some more options with placement (rehearsal room issues), and also see if I could get a hold of an actual two channel amp (t switch between fretted/fretless playing. I was trying to get a hold of the Neoline 115 cab on sale here, but as I can't persuade the guy to send it to Copenhagen, I am now seeking other possibilities... If I am going down this route, I am pretty hot for the Glockenklang Blue soul head. Light, and seemingly very well put together. If any indication, my fretless has a Glockenklang pre, and it sounds fantastic !... So it that is the 'house sound' consider me hooked !!!. Another option could be an Aguilar SG 500 SC, or something locally produced like TC-Electronic. I have a potential buyer for my 115 Combo, and the 210 Neoline cabs should not be too hard to shift either. A replacement I am considering is a couple of very nice Epiphani UL210 cabs for sale locally. Or maybe buying a new (gosh !) Neoline 115/212 extension cab, and keeping the 210 around. I am having my eye on the Genz Benz 210 cab on sale here as well, but even IF I could persuade the seller to wrap and send it, I am not sure 2x12" would cut it. But tempted still... My questions for the more expirenced here is (in a nutshell): How are the Epiphanies compared to EBS Neoline soundwise ?... I kind of like the very precise sound of the EBS units !. Would there be even a remote possibilty, that the Genz 212 would be enough for Prog. rock rehearsal levels (fairly loud !), or am I dreaming ?. Any other (2 channel) heads I should check out ?. Hoping for some pointers... Another (very distant, in my current GAS-attack) option would be just keeping what I got, and be happy with that. However, then I would likely spend some time and money at the shrink instead . Regards. Torben

[quote name='DiMarco' timestamp='1391631873' post='2359577'] It is a broadneck by the looks of it. This was mine. Expect something similar! [/quote] My long lost twin brother !!!... I'm just sayin'... If anybody sees this baby somewhere on a sale forum of sorts, PLEASE let me know !!!. A fretless 5 Pro 1 (BN) would pretty much complete my world !

Hi. My love for EBS Microbass have made me curious, as to other preamps out there. As a replacement, I have currently narrowed it down to two choices... Sound quaility and flexibility are the key paramters here . I am playing 1 or 2 frettted basses, and one fretless, only other effect at the moment is a tech 21 Chorus, and it is not likely that alot more effects will come into the setup... 1. The Lehle basswitch (The obvious choice somehow... Legendary !) 2. A Lehle d.loop sgos, and one or two other preamp pedals in any configuration. 2'nd solution somehow seems the most flexible, but I am slightly doubful about the effect on sound quality. Both the d.loop n itself, but particularly cabling it up with other pedals... However, it gives me more choice (also to 'shop' a great preamp at a good price). Fact is that I have a very very good offer on a d.loop, so potentially I could make this setup or a fair price. However... I am not going to save £100 or so to sacrifice sound quality. Any opnions or experiences with the d.loop ?.

[quote name='Kev' timestamp='1391366189' post='2356298'] Two votes for Dolphin, woop! On the subject of SSII and Dolphin, I have both and they are quite different, quite different indeed. [/quote] Seems that you Pro 1 is significantly different from mine. Mine is the 'old school' model with two Bart Humbuckers... Woods could the identical though . Never had my filthy hands on other (peoples) Dolphins, but mine is quite radically different from just about any other bass I've (not hat many... But a few under the belt nevertheless). In one word my Pro 1 is just plain rigid - practically no vibrations transplants into the body, and the general feel of the thing was a bit 'detached' at first. However, after the initial shock (it also has considerable weight, compared to it's size) there is definately a connection between me and the instrument. It has an incredible attack and tone, and the sustain is actually almost too much (sound fades very very progressively but slowly)... All in all I am a very happy bunny, but I would think the Dolphin is very much a bass you either love to bits, or hate like the plague...

My Warwick Dolphin pro 1 (1991, broadneck 5 string)... It took a little getting used to, but now I just won't do without it... Comparing apples and oranges a bit... But I do miss my Elrick NJS 5 string. Completely different in most ways to the Dolphin, but the Elrick did have alot of appeal to me !. My newly acquired Human Base fretless 5 is not completely without sex-appeal either though Have to agree on the 'Warwick statements' though... Fantastic basses, and very very tonally/ergonomically different model to model. Never got on with the Thumb, although I really really wanted to like it !. Considering getting a Streamer Stage II, but looking at the combination of woods, I would it is very close to my Dolphin Pro 1. So no hurry there
