orange 2x12 and 4x12

How is the sound stacked on top of each other compared to 4x12 by itself? im thinking of purchasing a 2x12 now and a tiny terror soon after to use with the 2x12 but would also use it for my stack with my ad 140.

id be interested in knowing this also, i have heard on this forum before that when you plug in a 2x12 along with a 4x12 that the 4x12 is not as loud as the 2x12,
but i dont know how true that is,

im sure acorcos would be able to awnser this one though

cheers

If you had the same speaks, VIN30s for example, and both cabs were the same impedence, and you hit both cabs with the same power, I would expect the 4x12 to be slightly louder due to that elusive acoustic coupling thing. If you ran the calculation, one would not be louder than the other (assuming you stayed within the SPL range that a 2x12 could hit). The reality is there's a coupling phenom that reenforces more than the equation would suggest...

I have a 2x12 stacked on a 4x12. The 2x12 is louder but it's also open back so I don't know how much of the difference is due to that. Both cabs use V30s.

Assuming two 16ohm loads....

You're splitting the signal in parallel and sending it to two equal loads. One load consists of two speakers and the other load consists of four speakers. Therefore the two speaker load is recieving equal power to the four speaker load, and thus the two speakers will be driven harder.

Yep, the individual speaks in the 2x12 will be getting twice the juice that the speaks in the 4x12 are getting...the open back thing will make a heck of a difference in how it disperses etc.

So the equation

so will the sound be "more full" or sound really crappy with the 2x12 overpowering it?

Do you suppose that six speakers will sound less full than two?

Personally, i would just go with 2 4x12's...........
