Tvad:
Atkinson's measurements: yes and no. My initial set of measurements reflected the general frequency response shape seen in his anechoic measurements, but the aberrations were less severe. I measured with the speakers set up on sliding glass doors (not a good idea, but listening positions in my listening room are very limited). The speakers were also powered by my VAC 70/70, which is a triode tube amp that I run with zero feedback and which can thus be expected to measure bizarrely due to impedance interactions. I reported my measurements in the following thread:

For aesthetic reasons, the final position for my Fremonts is on a solid wall and they measure quite differently there. I run them with either a VAC 70/70 or a darTZeel. With the darTZeel, the midrange measures flat within 2-3 db. from approximately 200 Hz. to 6,000 Hz., with only one exception: Atkinson measured a bizarre suckout of 25 db. centered at 4,000 Hz. With the darTZeel, I measured a suckout of approximately 5 db. near the same point. Atkinson also measured a dip of approximately 10 db. at 200 Hz. With the darTZeel, the response was down approximately 5 db. from 160-200 Hz. Atkinson measured a roll off above 4,000 Hz. of approximately 5 db., both anechoically and in Larry Greenhill's listening room. With the darTZeel, my response is down 3.5 db. at 3.15 kHz., but otherwise basically flat to 8,000 Hz., with a gentle rolloff from 12,000 Hz. to 20,000 Hz. My measurements with the VAC 70/70 and the speakers on the solid wall are pretty similar to the darTZeel-powered measurements, but ultimately a bit less linear.
While the frequency response measurements are what they are, many argue that other measurements are far more important than frequency response, and I subjectively prefer the Escalantes to the Salons, Dynaudios, V.A. Mahlers, Dunlavys and Ultimate Monitors that I owned previously. The Fremont is a complex design and I leave it to "Audio Oracle", who worked at Singer and Innovative in Manhattan for many years and who as a result has probably heard, sold and installed as much gear as anyone, to describe their strengths and weaknesses in the above referenced thread.
My sincere apologies for the diversion, but I recommend the Fremonts in good faith - I cannot hear their foibles, while I can hear (as can many others) the problems with the titanium tweeter in the WattPuppy and Sophia.
