The Summits need to be placed well away from the back wall with bass traps,
like ASC tube traps (reflecting membrane pointing away from the electrostatic
elements). I have my Summits 6' from the back wall and 12 ASC bass and
mid range traps evenly spaced along this wall. I also have Magneplanar Tympani
IV bass panels along side of the Summits (woofers disconnected). The mid
and highs are extremely detailed and smooth with no irritation and imaging is
fantastic. Also because the Summits impedance at higher frequencies is very low
(capacitance is high) requires a amplifier that can drive this load without distortion.
My Arcam AVR 600 handles this load with out any problems and the highs are
extremely clean at low or high levels. Combining the Martin Logan summits with
the Magneplanar Tympani IV bass is a match that not many audiophiles have
heard. I also extend the bass down to below 1 hz with the Eminent Technology
rotary subwoofer and the total combo is awesome and coherent.
