[quote name='cheddatom' post='515185' date='Jun 16 2009, 12:22 PM']I bought some studio spares NS-10s and they're a bit sh*t IMHO. Anyone else used these? Am I doing something wrong?[/quote] No, that's just how they sound They're more than just hype though, they really are very good for what they're used for, supported by actual science even! There's a reason why they became the near-field speaker of choice for so many studios -- and as mentioned, if a mix sounds good on there, it's likely to sound good anywhere. Acoustic Energy have now released a significant update on the theory which I intend to get a hold of when I've got the money. [i]Supposedly[/i], the woofer makes a good kick mic as well, if you reverse wire the speaker up as a dynamic mic. I've heard a few different studio types mention it, but I've never tried it, so it could be complete bollox.

i use one from time to time, never really need to in the band though. it won't damage anything as long as you use it properly. can't think of a reason not to use one if it makes life easier.

not bad but it feels like it's missing a certain energy, also the intro was a bit too long for my tastes. look forward to hearing more!

[url="http://www.talkbass.com/forum/showthread.php?t=531362"]http://www.talkbass.com/forum/showthread.php?t=531362[/url] I use to have a 1820 cab, just one 18", it was really heavy.[/quote] i think the 3620 was the cab i was thinking of when i mentioned a peavey 2x18 earlier, as i remembered seeing a few people with them on [url="http://www.foreverdoomed.com/forums/viewtopic.php?f=22&t=113"]this thread[/url] on the DFFD forums. didn't know the name of the cab though.

not knowing anything else about it i would say: it looks old, simple, and tough -- three things which get it a thumbs up from me

[quote name='alexclaber' post='514085' date='Jun 15 2009, 12:46 PM']I guess if I were doing a Barefaced doom rig then I'd bridge a big power amp into one or two Big Subs and then run a smaller valve amp into a Midget. That would be scary loud and deep and thunderous yet as dirty and mean as you like.[/quote] all while being lightweight and portable too ^_^

[quote name='joegarcia' post='513803' date='Jun 15 2009, 03:52 AM']Haha. I suggested that PD driver to him months ago! Thanks for backing me up. I know it's not technically perfect but it's the right compromise between sound and aesthetics in this case.[/quote] haha no worries as you say, it might not be the best solution from a technical standpoint, but in addition to the aesthetics i'd imagine the significantly lower cost of the one driver versus other solutions would make it at least worth trying.

[quote name='Finbar' post='511467' date='Jun 11 2009, 05:41 PM']I've always told myself this is better for my cabs, and a more efficient use of power, but will it make a big difference?[/quote] it is both, but the difference it would make would depend a lot upon your predominant bass playing style. however, i would stick with what you've got, if it were me.

[quote name='Mr. Foxen' post='513759' date='Jun 15 2009, 12:15 AM']So one of those BFM jobs looks bunches like what I'm after, but there is no way I have the space to be making one. Non sound considerations are being about the size of an 8x10 so it can sit next to it on stage. If I stick a modern sub driver in my W horn cab, is it gonna give me a bunch of lows, even if I have to eq it in (this sort of appeals as the sound of that cab alone is a useable sound, but the speaker is on its way out, due to age)? Will putting full signal into something designed as a sub damage it or just fail to make the higher stuff into sound?[/quote] it won't damage it, although it would probably make sense to use an active crossover before the power amp, as reproducing the higher frequencies will only expend power that could be driving the lower frequencies -- however, unless you're running the amp right on the edge, it probably won't make a huge difference. a good 18 could probably make that cab work for you pretty well. Something like [url="http://www.bluearan.co.uk/index.php?id=PDIPD186-4&browsemode=manufacturer"]this[/url] maybe.

[quote name='Alien' post='513409' date='Jun 14 2009, 04:45 PM']OK, just went back and had a quick look at the charts and then did a bit of basic arithmetic. They should actually only be good for 140dB (oh, [i]only[/i] 140...) but should be capable of doing that all the way down to 30Hz. I've based that on charts shown [url="http://billfitzmaurice.net/phpBB3/viewtopic.php?f=12&t=541"]here[/url] A[/quote] the extra ten or so dB you had was where the was coming from.

[quote name='Alien' post='513276' date='Jun 14 2009, 01:11 PM']That little stack should be good for around 150dB @ 40Hz if loaded with 3015LFs.[/quote] and how do you figure that?

That's harsh dude, i feel for you Unfortunately while it might seem clear as to the cause of the problem, it may be a little difficult to actually make the other band pay for any damages -- as they will claim it didn't happen while they were using it. Furthermore, it would be tough to prove that was even the cause of the problem, as they will likely claim that the power output of the head matches to the power handling of the cab. While i think it's likely the two incidents are related, you will have to hope that they are nice guys -- who knows, the bassist may redeem himself yet! He really should have known better though. Speakers tend to fail [i]during[/i] heavy usage however, not [i]after[/i] heavy usage -- so you may want to have a look in the back of the cab and make sure everything else is alright inside.

[quote name='Mr. Foxen' post='513267' date='Jun 14 2009, 12:53 PM']I am familiar with this, but the idea is the sound is a bit beyond what you are hearing with ears. If you seen Sunn O))) or Asva, a lot of it is about your whole body feeling the sound. The concern is when I'm playing a there'll be some 31hz there but much more 62 and 124 etc, but when I go down to the A, there'll just the the 50hz 100hz etc., so its as iff I carved off the very bottom. Those frequencies aren't there for your ears. I'm fairly sure my bass puts out a stringer fundamental than most as octavers track it really well, and when I'm putting it through a little cab that isn't taking the lows, there is a definite point the sound is lacking, even if the note is clear and the speaker isn't farting, which I guess is the natural low roll off.[/quote] well, the only way to go then is a lot of power and cabs that can handle it, really. a set of Alex's subs or a BFM Titan or something similar, coupled to an active crossover and a couple of kW of SS power. but really, the right high pass filter at 30 or 40 Hz is going to have much less of a negative impact in the lows than you think, even when it comes to shaking people -- it is really just going to spare the amp and drivers.

[quote name='Mr. Foxen' post='513254' date='Jun 14 2009, 12:31 PM']I'm using a low A, with the fundamental at around 25hz, so if it cut below 30, would myA lose something compared to my B, as suddenly a fequency is being dumped from the bottom? I'm aware you can't really hear that fundamental, but wouldn't it be a bunch like playing an A an octave higher?[/quote] the spacing of the harmonics differs, and so even if you can't hear the fundamental, your ear will synthesize it when you hear it. even alex's cabs are going to have a much lower sensitivity down at 30 Hz (and so are your ears, for that matter), most of what you will hear of the low A will be the second and third harmonics at 50 Hz and 75 Hz -- by filtering the frequencies below 30 Hz before the power amplifier stage, you will save a lot of amplifier power and unneeded speaker excursion, which you can then use to drive said speakers even harder in the range you want.

Hmm, well, tough to know then. I still think the above option of SS is going to be one of your best bets, but if you really want the tube option then something designed around a valve like [url="http://www.cpii.com/docs/datasheets/78/3CX1000A7-8283.pdf"]this[/url] might be more practical -- although still expensive and heavy. no ideas where you'll find a design, or an amp, though. if you can get your hands on one of the old peavey 2x18's or a folded horn design maybe (i know HH did some in the early eighties), that would likely work as well. having said that speak to Alex, I still think either a Vintage or a pair of his smaller cabs (perhaps with only the LF driver in) would do the trick nicely. was that valve amp you posted every designed as anything more than a bench experiment? it's just that the size, weight, power requirements, cooling, part costs, and inefficiency likely to be present kind of limits any practical application. [edit: i envision your bass rig looking something like [url="http://www.hhamplification.co.uk/gallerypic.asp?bigpics=dbfiles/gallery/pa2.jpg"]this[/url] before long.]

[url="http://www.thomann.de/gb/db_technologies_hpa_2800.htm"]This[/url] and [url="http://www.thomann.de/gb/peavey_pv23_xo.htm"]this[/url] with a BF Vintage with 3015LF's? I don't really know what your budget is, so i'm just throwing stuff out there. Low frequencies tend to require a lot of power so valves are probably not the most efficient solution, also SS amps will usually have a lot better damping, which should help keep the low frequency reproduction a bit more controlled.

I sat at a kit with little JLP (7) at another one along with a class of other people & a chap instructing at the front. We were all led through how to do play a rhythm & fill and use the kit.[/quote] that part was very surreal, watching a field of people all drumming the same thing -- silently. very strange to watch, i found ^_^ also, i felt really bad for Jim Marshall, the poor guy kept signing the desk! in other news, i thought it was going to be a lot better, and larger, than it was -- and with a lot of companies not there, and a not insignificant entry fee, I can't say it was really all that great. I don't see myself going again.

Josh is a great guy to deal with, good communication, excellent buyer and very friendly too. Would definitely deal with him again, all the best with your new Akai desk!
