I just discovered these cabinets a few weeks ago and they seem pretty awesome. I had already been sort of thinking about building one. I got a scored a free 15" speaker today from work which is pretty awesome so now I definitely want to make one. I picked up a eminence kilomax 15 speaker which seems pretty awesome after looking it up. I notices on the plans that it recommends a eminence 3015Lf for the build. I was wondering if it would be worth using the kilomax speaker instead. Upon further research they seem similar but have minor differences. The kilomax is a bit more expensive. Would it be worth using this speaker for this build or should I chub the cash to get the one recommended 3015LF?
