1x15 vs.4x10vs.2x10

You can disagree all you like, but you would still be wrong.

The tone of a cab is determined by the speakers T/S parameters combined with the cabs design. There are 10" subs, and 15's used for mids and guitar. Size tells you nothing.

Really? Wow, after being a musician for 50 years and an electronics technician while in the Navy, I guess I haven't learned very much. So lets all switch to 6" speakers. They are cheep and easy to carry around.
 
Physics doesnt trust your ears.
Music is based on physics, but physics isn't music. When solid state amps first came out, all the "experts" said they were better because the sound was clean. They were wrong. Tell you what. You use the speakers you like (don't know how anything sounds good through a peavey) and I'll use the ones I like. We can both have our own opinions and leave one another alone. How's that sound to you?

Thats kinda cute.... *condescending puppy head pats*

The beaming frequency is one of the only traits you can tell about a speaker based upon its diameter. Larger means it beams at a lower frequency. Putting two 10's side by side means they act like a ~19" driver instead of a ~10" one.

Per my choices in gear: They work for me, but play what you like.
 
Really? I thought sitting the cab base flat on the floor gave you a (roughly 6db? Not sure) coupling boost? I've never had a cab with castors until today, so I don't know, but I'd planned to take em off for that reason.

The actual mechanical coupling isnt needed. (actually there should be minimal transfer of energy from the cab to the floor.) As long as the cab is ~20" from the floor you gain acoustic coupling.

Ah, righto. In that case I'll leave the castors on, they do make it easy to position. I hadn't even considered mechanical coupling, I'd only envisaged acoustic coupling (see image). But that makes sense, I sort of thought that within coo-ee of the floor the sound waves would still be bouncing back up.

<sigh> Dave to a search on the subject in these pages. You are incorrect in your thinking. That said try stacking your 2x10 with the drivers vertically aligned above the 15" driver. may look odd but it will probably get you out into the room more consistently.

The thought that a larger driver produces more lows is a myth that has been debunked for a long time now.
 
Very generally a pretty valid point. Gotta say, if price isn't such an issue, I favor a "vertical" 410 (210 x 2) with quality 210s. Performance of similar 215s (or 115 x 2), but raised higher so the sound is closer to ear level allowing you to hear it better. Of course you can always elevate a 112 x 2 or even a 115 x 2.


You mean, like this? :-)
