An addendum to my comments previously submitted.
For those of you who (after listening) do not think the QUARTETTES have enough BASS extension and power, John also has a proprietary matching sub-woofer created specifically to pair with the QUARTETTES. The finish matches, together with the styling, and, of course, completely eliminates the need for stands, in as much as they are ONLY sold in pairs. In paino gloss black they make a striking pair, mated with the QUARTETTES. They are self powered, of course. Rear firing in design. Frankly I keep my sub turned off most of the time because I have found that 90% of my listening does not require subs, and the bass power and extension is all a man could ask for. ! But for the "power crazed" it's a match made in heaven.
THAT'S ALL
