Members Faber Posted November 25, 2010 Members Share Posted November 25, 2010 Stupid question I suppose but I have very little experience running extention cabinets with combos so I don't know how great a difference it will make, if any. I have a Soldano Atomic 16 20w 1X12 combo. Fine classic rock crunch sounds out of this thing but it's JUST shy of being able to hang with the band volume wise. Now, I love the sound when I get to push the power stage (volume at 7, master at 9-12), so ideally I'd perfer if I could make this amp a little louder rather than finding another higher wattage amp that I then can't run as hard. Will an extention cab help me get there? Link to comment Share on other sites More sharing options...
Members Badside Posted November 25, 2010 Members Share Posted November 25, 2010 From experience, the biggest difference will be the sealed cabinet (most extension cabs are sealed, while most combo are open-back). This will give a much more solid bass and most likely hang with the band better. Link to comment Share on other sites More sharing options...
Members LYSOL Posted November 25, 2010 Members Share Posted November 25, 2010 No, it will not and if you try hook any old 4x12 up to a 1x12 combo the Ohms will likely be wrong and you can kill your amp quite easily if you don't know what you're doing. 20watts powering a 4x12 is a bit silly anyways, you'd want at least 50 minimum as a 4x12 at 20watts is overkill IMO.A 2x12 would be better suited. Just make sure you check the ohms of the current speaker and make sure you keep the new speakers at that ohms, total. Link to comment Share on other sites More sharing options...
Members Alecto Posted November 25, 2010 Members Share Posted November 25, 2010 Running your amp through a 2x12 or 4x12 will make your amp appear to be louder, but the bigger rewards will be tonal, not volume. Oh, and there's nothing wrong with plugging your 15-watt combo or head into a 4x12 cabinet as long as you have the ohms matched up. A huge advantage is that you can crank the master volume without killing everyone's eardrums. The Mesa-Boogie TransAtlantic sounds killer through a 4x12.

Members Special J Posted November 25, 2010 Members Share Posted November 25, 2010 Depends on the ohm ratings, efficiency of the speakers, cab design, etc. IME, 4x12's are generally overkill for everything but metal or playing big stages, and are a pain to lug around.

Members Belva Posted November 25, 2010 Members Share Posted November 25, 2010 What's the spl on the amp's current speaker? Efficiency was mentioned. SPL is a measure of this. IIRC it's how many decibels at one meter one watt will produce from a given speaker. So if your amp has a speaker of, say, 80db spl and you yank that in favor of one that has an spl of 100 db you gonna get more balls. It also stands to reason that one 100 db spl speaker will be louder that a 412 loaded with 80's. Link to comment Share on other sites More sharing options...
Members cratz2 Posted November 25, 2010 Members Share Posted November 25, 2010 Would you be running the speaker in the amp PLUS the speakers in the cab? It will definitely be louder because you are moving more air, but depending on what speakers you have and what speakers you get, it might not be a night and day difference. For example, if you have a very efficient speaker like an EVM 12L in there now, and you add two relatively inefficient speakers like Greenbacks, it will likely not make a big difference. But if you have a Geenback in there and you add two 12Ls it would be tremendous. Link to comment Share on other sites More sharing options...

Will an extention cab help me get there?Depends. I found mine to be plenty loud for a good balanced stage mix with the band. A closed-back 2x12 or 4x12 should give you a better lowend, so it could mean lowering your bass knob, which in turn, would create a little more volume capability. After that, it boils down to efficiencies of the speakers in question. And of course, match your impedances regardless. Link to comment Share on other sites More sharing options...

Members megawzrd Posted November 25, 2010 Members Share Posted November 25, 2010 More speaker = more moved air = louder ! ding ding ding plain and simple When I went from running my 1x10 40w combo solo to running in parallel with a 2x12 cab it was noticeably louder and fuller. I had to redial my volume and gain to adjust. Link to comment Share on other sites More sharing options...
Members Flogger59 Posted November 25, 2010 Members Share Posted November 25, 2010 Mr Math here. Assuming that the speaker in your combo is the same as the ones in the 412 (for argument's sake), doubling the number of speakers will net you an additional 4db (about). Double that again with the 412 and you're 8db louder, which is within a hair of twice as loud. Real world conditions may vary. Link to comment Share on other sites More sharing options...

Members sylvesterlowery Posted November 25, 2010 Members Share Posted November 25, 2010 I've cranked a Valve Junior head through a 1x12 and a 4x12, and I much prefer the bigger cabinet. It pushes more air and the sealed back does give better bass response. Link to comment Share on other sites More sharing options...

Members tlbonehead Posted November 25, 2010 Members Share Posted November 25, 2010 Please rebut and learn me sumpin'.I believe you are forgetting to divide the available power when considering more than one speaker. The less power you send to a speaker, the less the cone moves, therefore, the less air it will move. So a 4x12 cab being fed by 20 watts would only have 5 watts going to each speaker, vs the full 20 watts going to a single driver. Link to comment Share on other sites More sharing options...
Members LYSOL Posted November 25, 2010 Members Share Posted November 25, 2010 More air = more volume yes but to a certain extent as its not gonna be like a doubling in volume or anything. Say you have a 100watt amp and you want an amp twice as loud, you will need a 1,000 watt amp, not a 200 watt amp. This was the whole point! Mr Math here. Assuming that the speaker in your combo is the same as the ones in the 412 (for argument's sake), doubling the number of speakers will net you an additional 4db (about).

Amp volume doubles with a wattage increase by a factor of 10. Link to comment Share on other sites More sharing options...
