Looking to sell this wonderful subwoofer. I bought the driver from GR-Research SW12-4, and the amp, A370PEQ, from rythmik audio. The driver is based on the 12" rythmik driver except that instead of aluminium cone, this uses paper cone. Paper being lighter is more dynamic, and is recommended for systems that need to be crossed over at over 80Hz.
I built the cabinet to be bottom firing in void-free baltic birch, and veneered it with manufactured ebony veneer and jatoba inlays. Then they were finished with waterlox gloss finish. The dimensions follow the recommended size by GR-Research : 15.75" x 15.75" x 17.25"

Asking for $500.00, and highly highly prefer local sale (Dallas-FortWorth region). The sub weighs quite a bit, and i've no packaging.
