They are up and playing for the first time. My first impression is they sound unlike most single driver speakers I've heard - no shout, no tizzy presence, and most importantly, full rich deep bass at any sane volume level. Female vocals seem to have just a bit of a "cupped hands" sound, but otherwise there are no sonic hints they're full range driver speakers. Very easy to listen to.
If anybody in the Houston area would like to hear them, I'm hosting the Houston Audio Society meeting at my house next Saturday, and the meeting topic is a comparison of the sonic characteristics of five very different speaker designs - a pair of Magnepans, a MLTL full range bipole design, the Brines Acoustics TT-2000's, a pair of inexpensive diy line arrays (the Art Arrays), and a more typical "high end" design, the Selah Audio 2.5-way Texas Revelator Towers using Scan Speak Revelator drivers. Pm me for directions.
