Good choice of driver. I'm also using Epic10s but in a pair of dual opposed, side firing base bins. Try/simulate a smaller box volume and yours will take more power without bottoming out. QTC of .635 is what I settled on. With 2000W into a pair, they cross Xmax-linear at 22 Hz and never get near Xmech. I chose Epic10s because they needed the least volume. Anything else of comparable or better performance needs >= 2x the volume and costs a good bit more. With boundary reinforcement and room gain, the Epic10s should be more than good enough. I got mine at the PE Black Friday sale for $139. ea.
