Mike, why not use smaller drivers?
Because my 15" has the required VdThis is no bill fitz horn
A horn that is longer,with a smaller driver will be displacement limited in the midband which is what i DONT want..
I can input 240w rms and still within xmax with my 15"
+ i already own it,so why buy another speaker for no reason.
The reason i wouldnt go buy a lab12,is that the BL is lower causing a larger unloading effect at the horn flare frequency.Also I dont have cash pouring out my ears
Regards
Mike.e
