From Kef:

An extremely elegant small floorstander, the Q35 offers the audiophile an outstandingly sweet midrange, fast bass and accurate treble performance. The new Uni-Q® driver provides greater clarity and accuracy than previous designs and the Q35's stereo imaging ability is second to none. A bi-wiring facility is provided, as are spikes and the system is magnetically shielded for home theatre duties.

From Me: The speakers were always partnered with a very capable Marantz PM55SE amp (also for sale) and were never driven hard.  There is some superficial damage on both speakers with a small nick on one and a scratch on the other (displayed).  I have set no reserve on these speakers and they are pick-up only.  The floor spikes are not included.
