@mdalton - while age related hearing loss does manifest itself in the high treble - say above 14K, the most problematic and very common manifestation of hearing loss is in the 2-6KHz region - so if Wilson was driven by demographics they would be boosting that region, not cutting it. Wilson speaker are very revealing of what comes before them, so a lot of criticism of the speakers being bright is a case of shoot the messenger.
Stereophile - Sabrina 5
Hate to rag on Sterophile again, but one of two things are true. One, the Sabrina speakers they reviewed were wired incorrectly or Wilson is now shipping with inverted midranges.
All that work to reduce distortion to vanishing levels only to totally ahem, add custom flavor to the frequency response.
Honestly if I was reviewing this speaker I'd have stopped to reach out to them before publishing, just to be sure this speaker shipped as intended.

Betweennthe ages of 40 and 65, on average even men don’t have much hearing loss below 4k, but we do experience some above 4k. But you’re right, after 65 or 70, again on avg, we start to experience fairly significant loss below 4k (tho again, the curve is much steeper above 4k. Regardless, Ivwas just trying to posit snvexplanation that reconciles the measurements, including a very significant dip between 2k and 4k, with what many of us hear when we listen to Wilson’s. |
I stand corrected… |
EPDR This keeps getting mentioned so I thought I could clarify it a little. EPDR is often discussed as a way to improve our understanding of the interaction between an amplifier’s output impedance and the speaker load. The idea is that EPDR tells us something about the current and voltage at the speaker terminals that would result from this speaker being attached to any amplifier. Unfortunately this is NOT the case. EPDR is about heat at a linear amplifier’s output transistors. "Peak Dissipation" here means at the output transistors, or heat sinks. In particular, if you care about EPDR, then use a Class D amp, cause EPDR does not apply at all. It also has nothing to do with an amplifier's output impedance or current limits, at least how you think they would, and even Stereophile's original articles don't make this claim. They just sort of let you feel they do. I wrote about this in a great deal of depth here. Obviously, nothing good about overheating your amplifier, but I would be much more concerned, if not curious, as to how Wilson can get an 8 or 4 Ohm woofer to go all the way down to 2 Ohms. That’s quite an impressive feature. |
