I have both the Spendor Classic 1/2 and 2/3e speakers. Both have a mid-range to die for, with the 1/2's having a slightly deeper bass but, as others have said, bass is not why you buy the Spendor Classic speakers. New Spendor 2/3's sell for about $3,500; new 1/2's for about $5,500.
My listening room is 14'x15'. I use a solid state Audio Analogue Puccini integrated amplifier (50 watts) and a Pathos Classic One hybrid integrated amplifier (70 watts) to drive the Spendors to very loud levels. They have a flat 8 ohm impedence and are easy to drive. I also use an Eastern Electric M-520 tube integrated amplifier (18 watts). The music is just magical, whether powered by a solid state or tube amplifier.
