Re: Impedance question on double 15 with a horn
Hi Allen,
Here’s the catch – a double 15 and horn will not work “correctly” unless you can cross the15’s over at about 500Hz. 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.
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'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.
