That’s why cinema systems do that, and that’s why EAW also have a pair of 7” drivers in the LA325 … and that’s one of the reasons (the 2 x 7”) that you like the sound of the EAW.&nbsp; The problem you have is that a horn that will fit in your box will not be large enough to cross that low, and you don&#039;t have any mid drivers that cover 420 Hz to 2kHz (as aguess) like the EAW.Your box will work, but it will have some serious performance compromises no matter what you do, particularly with respect to its polar response.…anyway I hope what you come up with suits your needs.</blockquote>
