Bump! No subwoofer required, these things sound very good! You won't find a nicer pair for this money. Most have yellow/brown cones from the years of cigarette smoke they were around. For those interested, the amplifier is a power amplifier, there is no volume control. You can either hook it to the pre-outs of an A/V or stereo receiver, or use a dedicated pre-amp. Gain controls are found on the back of the unit. The amp itself weighs about 40lb, and the speakers weigh about 30lb each.
