[quote name='Wiggybass' timestamp='1349267267' post='1823977'] Hmmm...sorry, simply not true. This is physics and its principles govern all things regardless of marketing. Let's look beyond crappy, frequency-limited backline and into proper audio systems, like a big modern PA designed to deliver full-range audio to large crowds. In all modern systems the full frequency range is divided electronically into bands, usually four - HF, high-mid, low-mid and LF. HF is always produced by 1" or 2" compression drivers, the mids are usually tens or twelves and the LF is almost always some arrangement of EIGHTEEN inch drivers in ENORMOUS cabinets. Now, if all speakers could reproduce low frequencies with the same enthusiasm, why go to all this trouble? The answer, of course, is that they don't - they physically can't. The longer the wavelength you're looking to reproduce, the larger the device has to be. At 100Hz (the open G on a concert-tuned bass is 98Hz), the physical wavelength at sea level and 20 degC is 3.4 [i]metres[/i]. Yes, tens will do that but not with the same efficiency of a fifteen of equivalent performance and sensitivity. This of course all based on a one-speaker to one-speaker comparison. The practical issue comes down to how much cardboard moves in and out when you play, and thus how much air is physically displaced and then picked up by our lugholes. A 4x10 against a single 15 with the same amp power will be louder because it's moving more air but in frequency response terms it will not reproduce low frequencies as efficiently. Which incidentally explains why you're quite right about a 4x10 drowning out a single 15 - for those to balance in terms of physical loudness the 4x10 would have to be turned down a bit. As for variances between venues, again it depends. Reflex cabs are much more reactive to their surroundings than close or front-ported cabs, that alone would make a lot more difference than the size of drivers they contain. But surely that's what the EQ is for? [/quote] Have a wee read at these & things might make a little more sense to you. http://barefacedbass.com/technical-information/speaker-size-frequency-response.htm http://billfitzmaurice.info/forum/viewforum.php?f=10&sid=239e993b6a548da81514b45176b314cb Smaller drivers give a better dispersion than larger ones. 2 10" drivers vertically arranged in a cab the same size as a single 15" will give out a better dispersion. It's nothing to do with driver diameter on how low it can go, but how much it can move. The reason behind 15's & 18s is that cabs are cheaper to produce with a single driver.

Just saw the finished job. Very nice! Next build? Fretless???

[quote name='charic' timestamp='1349187049' post='1822969'] BTW It is seriously bugging me that the pedals run right to left! [/quote] Are you a lefty? You could run them the opposite way & get longer patch cables or to confuse people you could run them from top to bottom!

Yes & No. You can add another 8Ω cab. The amp puts out @300-350 watt at 8Ω & 500 watt at 4Ω. For an alternative, I'd get 2 2x10 cabs if you're going for Markbass gear. Vertical 2x10s have a much better dispersion across the stage/audience than a 4x10, but if you're playing through PA, then this may not bother you.

[quote name='Wiggybass' timestamp='1349207930' post='1823389'] No reason whatsoever why you shouldn't mix any speaker sizes you want so long as you don't go below the minimum impedance (stated in ohms) that your amp will safely drive. Going below that point will make your amp work very hard and likely shorten its life. Most bass amps I've used seem to be happiest working at 4 ohms, and will typically deliver about 25% more power than when working at 8 ohms. What size you prefer depends a lot on how you use them and what music you play. Fifteens react slower (marginally) but will reproduce lower frequencies (typically regarded as those below about 160 Hz) more readily, so can be good for the deep bass required in dub, reggae, house etc. Tens react faster (marginally) and will not 'go as low' as larger speakers, simply because there is less cardboard moving in and out, but personally I prefer them for reasons of both sound quality and portability. I used an Eden 2 x 10 plus 1 x 15 setup for a while and it was OK, but since I bought my first 4 x 10 I've not really used anything else. By far the loudest rig I've owned was an original Trace Elliot 300w head with two T-E 4 x 10s, which, despite the modest power of the amp, set off car alarms 50 yards away at half volume outdoors... [/quote] Sorry, but quite a bit of that sounds like you've been filled with marketing codswallop. The main reason you shouldn't mix driver sizes is that you'll get unpredictable results from venue to venue. As for 15s producing lower frequencies, it's just not true. Marketing gobcrappers would have you believe that, but if you go for decent drivers from the same manufacturer, the specs on how low a frequency it can produce have no baring on driver diameter & more so on how the cab has been designed. keeping to the same size drivers means you'll get a consistent sound from venue to venue. I'm not saying don't go for a 4x10 & a 1x15, but you won't really be hearing fully what the 15 is doing as the 4x10 would probably be drowning most of it out.

Have you tried popping the DB through Markbass gear to see if you like it? I had a DB through my MB 2x10 combo & I thought it sounded superb.

[quote name='Rick's Fine '52' timestamp='1349187078' post='1822970'] Indeed, I was slightly worried after posting, that you were gonna come back and say it was a picture of you, and what was my f'ing problem!! [/quote] I wish I would have thought of that!

[quote name='Rick's Fine '52' timestamp='1349180965' post='1822812'] I can't cope with the orangeness of those two nuggets!! [/quote] You did ask for Orange folk!

A simple & cheap option would be to make your own 2 part pedal that 1st splits the signal so you can put your signals where you want & then the 2nd part would be a simple 3 channel mixer to source your signals back to one. Easy to make & fun too.

Can you solder?

I'd try stacking them both ways & see what sounds the best when you're not directly in front of them. Nice rig, matches your bass too!

[quote name='Dave Vader' timestamp='1349092606' post='1821571'] Yep, well done mate, and had we been using a different voting style, xgsjx would have been in my 2nd choice box. So you nearly got a vote mate. [/quote] Cheers Dave. Looking forward to this month's comp. More so to hear what everyone else composes.

Well done Skol, a worthy win against a load of excellent entries! I'm the only one who didn't get a vote. That means I need to put more of an effort in for this month!

I'd suggest a 2nd hand MarkBass LMII & a decent cab (such as that TC Phil mentions). There's tons of good stuff to be had 2nd hand

1st thing..... IGNORE THE WATTS. Go & have a read in the amp & cabs forum for some clarification. I'd try a BF Midget with your Ibby amp & see if it's what you're looking for. Alex gives a 30 day trial & you can add a pre or a pedal if you don't want clean. I've giged with a single 12" cab in a 2 guitar rock band & it's been gigable. It really depends on the venue & what you're using.

I'm with Dr Dave. Most of the time my thumb is floating, but it will anchor onto a pickup or the E string without me even thinking about it to suit what I'm playing. It's hard to play slap with your thimb anchored though! Maybe a good thing.

[quote name='Skol303' timestamp='1348671762' post='1816756'] PS: genuinely stoked that I have 6 votes! Cheers folks, that's warmed my cockles on what is an otherwise crappy day [/quote] I don't think there's a bad track out of all the entries (which makes it a hard choice), but I think you have a very accomplished track that fits the theme well.

A large engineer's square?

Can you fiddle the votes? I'm gonna win the photo comp this month if you can!

! Shocking!!!

I can only agree with what's been said. Top bloke & made me smile reading this.

Is it an unbiased review of blue & green LEDs?

Root 5th all the way. Dont stray & play Country! Wait a min.... I play a little Country & follow the vocal line (but with different notes). Have you thought about playing random notes from the scale? http://soundcloud.com/xgsjx/stars-guitars

Doesn't work for me either.
