The Grand Inquisition must return – There's a new heretic in town. It's Montreal's Robert Gaboury now with Heretic Sound System and their AD614 [$7'290/pr], a front-vented 12" coaxial two-way with a 2nd-order 1.7kHz Linkwitz-Riley series filter and broad-shouldered Birch ply cab. The tweeter behind the mid/woofer's dust cap is a 1" compression driver in a short exponential horn. Bandwidth is 45Hz-22'000Hz and sensitivity a high 97dB with a likely non-complex 8Ω impedance since 3wpc amplifiers are mentioned.
