Project I designed about 5 years ago. Uses coax 8" (Radian-based), flanked by LCY ribbon supertweeter, and dual TC Sounds 10" woofers assisted by triple TC Sounds 10" passive radiators (on rear of cabinet). Bass is self-amplified by 500w amp mounted in bottom of enclosure. Response flat from 16-47000 Hz (-3dB). 95dB sensitivity on main section (concentric/ribbon), very flat 8 ohm load. Cabinet designed by me, with one pair built.
