Speakers that open up at low volume levels


I'm trying to come up with a list of speakers that open up, sound full, and alive at low-med volume.   Lets keep the list to speakers under $7500.00 new.

My 2 cents.... I have some open baffles with audio nirvana 12" drivers in them and they sound better than any box design at low levels to me anyway. 96db
My Eminent Technology LFT-8a sound very balanced at low volumes and NOT efficient. Good for condo living!
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.
Sky isn't limit in this case and there will be trade-offs and trade-off may be the dynamic range. I'm absolute freak on dynamic range and the larger one gets my choice.
