Jeff---The ET LFT-8, an excellent loudspeaker with a for-some-reason very low profile. You're right, it's rather inefficient, yet imo sounds better at low volume (as well as high!) than Magneplanar's 1.7, a very similiar low-efficiency planar. A lot of Electrostatic speakers sound great at low volume as well, perhaps as a result of their unmatched transparency.
