As a long time audio salesman, short time store owner, and now a Fremont dealer I think I can give you some valid opinions on the Fremont.
First the measurement issue doesn't necessarily mean anything relevant. Most great sounding tube amplifiers measure poorly yet sound magnificent, this is especially so with many SET amplifiers.
Many time measurements don't correlate with what we hear and many times products which measure impressively often sound less than desirable. In the case of the Fremont its unusual design makes conventional measurements difficult.
I have heard the Fremont at numerous times at shows and honestly they never totally impressed me. However, I now have a pair in my posesion and my opinions of them speakers have changed drastically.
What the speakers do they do extremely well, and in some ways outperform many other speakers. some of which are much more expensive. However, the speakers are very setup sensitive.
I found bliss with a 30 watt Class A Master Sound 845 SET amps which made absolute magic with the Fremont. Other amplifiers didn't sound so great and some of these amplifiers were fantastic with other speakers.
Also the bass of this speaker is very room and setup dependent. I have heard the Fremont go very low in the bass in some rooms, but in my very large room they didn't go as low as I expected them to.
Pluses: Dynamics are outstanding, the speed of this design is unbelievable, the treble is smooth yet quite detailed, the sound stage is also very wide and the midrange is very natural! The bass is tune accurate, and they play extremely loudly and run on tiny amplifiers.
Minuses:
Room dependent, setup dependent and very sensitive to partnering components.
So the Fremont is an enigma. it is a very complex design and can reward its owner with breathtaking sound but it is not a panacea,
I have on occasion played the Fremont with Escalantes' Uinta sub woofer and this combination is truly mind blowing!
If you add it up the Fremont and Uinta combination is expensive but hardly insane for what you are getting for the money: at $19k for the speakers and $7k for a $26k combined price tag in their starter finishes.
In perspective the raved over Magico is $25k and has no deep bass to speak of. The Fremont uses much more expensive drivers, plays louder, has greater dynamics and runs magnificently on tiny tube amplifiers and will play to levels unheard of in audiophile speakers.
I would put a Fremont/Uinta combination up against a pair of Wilson Maxx any day of the week. So it comes down to what you are looking to achieve.
The Fremont it is a speaker which can reward its owner with some very special qualities but unless you are careful with it the results will not come through.
