.75 qft isn't too bad really, thats pretty typical. What other woofer offers this kind of output and needs less airspace?
I'm thinking .75 is doable in the KC, but you have more experience with building boxes than I do. I'm trying to figure out how it would compare to a
W6 Because I want good output and SQ like a W6 would provide only I need a 12" that would fit!
* Guess We Can Still Hope These come out soon as well but to be honest I have been waiting a year and 1/2 for something that will Provide decent SQL!
