I believe there use to be one offered by Technics that had a channel for sub amplification. Some high-end receivers might have assignable channels, as well. Even if you find one, I don't recommend it. Sub drivers are ussually 4 ohms and require more output than the rest of the speakers, especially for HT effects. It will impact the rest of the channels by trying to drive the sub. The power supply rail voltages will dip significantly, and possibly cause clipping and possible damage to the tweeters. Also, decent sub plate amps can be had for less than $150. Parts Express has a 250W@4ohm. Many people use this plate amp to drive long throw 10", 12", and 15" subs.
