haha, of course it does! Mathematically...

But what about when it comes to cabs? I heard a 2x15 about a month ago with no PA support and it was hitting me hard from a good 15 feet or more. That I like. Would a pair of 1x15 cabs be just as effective? Less? More? I'd like to hear both theoretical and practical experience or insight.

Thanks!

a 2x15 and and (2) 1x15's will sound different - they are different cabs...

I have 2 1x15's. They can still make the ground shake

I have not tried a modern 2x15, tho.

Do you think they would go better stacked vertically or side by side?

i would say stacked

i prefer 2 115's or 2 112's (this is what i have) as opposed to 215's or 212's......i don't know why, but i just do.

I think your comparing apples to oranges so to speak. You have too many different cabs designs for the 1x15 and the 2x15 cabs that you just have to try them. I can tell you that my Trace Elliot 2x15 cab makes people flinch it hits so hard and tight.

that's true as well

Right on...

So let's compare apples to apples then:

Ever heard a pair of Trace Elliot 1x15 cabs in comparison to your 2x15?

Or has anyone, for that matter, compared their 2x15 rig to a similar 2x115 rig? Or vice versa?

Or how about your 2x12 to a pair of 1x12's, and vice versa? Is the difference so detrimental you'd never do one or the other in place of it?

Curious.

for instance, aguilar didn't intend to have the 2 gs112's sound like their 212's.....also, my back won't let me carry bigass cab's anymore...two small cab's are fine, though.

also my 2 112's sound tighter (plus i mixed two diff 112's)

I heard som wise sage once utter that two speakers in the same cabinet picked up 3db by the coupling effect. Putting two identical cabinets together may or may not achieve the same coupling effect, depends dosen't it? How close do the speakers have to be to "couple" ? Maybe thats the question, not sure. Cant beat the portability of two seperate cabs though eh?

There is absolutely no way to determine which is better than to simply try both an decide.

There are too many equations involved to do this mathematically or physically, there is coupling of the speakers, on and off axis response of the two cab designs, the alteration of tone created by the addition of an isolated airspace for each driver, there's just too much to account for...

I wish I could give you a (2)1x15 vs (1)2x15 Trace comparison. I have played through one 1153 cab (and all other equipment being the same) it was not as punchy, had more of a low end bias, and ofcourse it wasn't as loud. Thats the best I can give you. That being said I still really liked playing through that cab but I'll stick with my 1524
