    Phase Linear 400 pots

    Does anyone out there possibly know what spec audio taper and linear taper potentiometers an Energy AS-180 subwoofer takes? I dearly love this big old woofer and both pots are shot and need replacing. They are both labeled “100k”, but I’m uncertain as to wattage... Any thoughts out there? Thanks!

    PSB Subsonic 6i Repair

    Hello all, I just recently acquired a PSB Subsonic 6i that I think might be worth repairing. With the front ports, front volume and crossover, and its reputation for being good for music, I thought it might be put to good use in my system. Things I know: - The speaker works fine - confirmed...
