I have some Celestion 15ftr3070c woofers, 510 clone horns, and EV DH1A compression drivers. I have used the woofers and CD in a k402MEH and they worked great, crossed them over at 500hz. This project will be for surrounds and maybe for a center channel (with the MEHs for the front channels). I still have a 2nd pair of MEHs that I could use, but I am trying to keep the size down. I have a Xilica xp4080p crossover and some Icepower 125asx2btl amps to power each driver.
