JA's measurements of the Nova Be

confirmed there was some cabinet resonance but apparently (according to his portion of the review) he did not feel he could hear that on extended listening to music:
There is a small glitch just below 200Hz in the impedance traces, which would imply the presence of some kind of cabinet resonance at that frequency. I hadn't taken an accelerometer to Minnesota, but I did listen to the half-step-spaced tonebursts on our Editor's Choice CD (Stereophile STPH016-2) while listening to the walls of the Nova Utopia's four individual sub-enclosures with a stethoscope. The tweeter cabinet was absolutely inert, but I could detect some high-Q behavior around the F below Middle C (175Hz) coming from the sides of the two midrange enclosures. This was so low in level, however, and restricted to such small radiating areas, that it should be subjectively benign. Certainly I heard nothing in the hours Paul and I spent listening to music that suggested the presence of cabinet-induced coloration.
JMlab has this reputation for poor cabinet design in the past, and apparently people are still going on about it ? Does anyone feel that the speaker's sound is suffering as a result ?
I am not so sure this is a problem (e.g. Nova or Alto Be).

The mass + rigidity of the speaker stand is crucial too - tonemaniac 06:11:27 07/1/04 (0)

Heard this on the Grand Utopia's as well. Not what I'd expect from a $80,000 speaker. nt - gme109 20:40:42 06/30/04 (0)

I have my doubts about this logic or permutations thereof - tonemaniac 12:09:22 06/30/04 (1)
