Rogers XA-75
Little is documented about the Rogers XA-75. The record shows a subwoofer system, offered alongside Rogers' L35B speaker, with its own amplifier and electronic crossover. A classified ad in Audio (March 1981, p.76) lists a used "Rogers L35B & XA-75 Subwoofer, Amp, & Elec. x-over" at $900.
A components listing in HI-Fi-Stereo-Buyers (1981, p.194) puts the XA-75's crossover at 150 Hz in its normal setting, with the bass section at 8 ohms nominal impedance. That's about all there is. No full specification sheet, review, or production history has surfaced so far.
