Hey all, here's my current setup:
Marantz 2270 (with remote power on/off and volume control, [] ) with 1986 Forte mains. I recently won an academy off ebay and I've got a Vantas DPA-S50 for center and surround amplification (although I'm not running surrounds yet). It's a 5.1 surround processor with three 100W amps inside. It tracks the voltage in the speaker wires produced by the receiver (to the mains) and adjusts the level of juice to send to the center and surrounds. Pretty curious beast, it is. If you're curious why I bother with this instead of going with a fancy new HT receiver, well, this system is mostly for 2-channel music, and I love my old Marantz!
Anyway, let me get to the question already. I know the academy is -3dB down at 65Hz. Should I be running a high pass filter inline with it to avoid damage to the drivers from low frequencies? Thanks! Rob
