John Ashman's recent post:
"Crossovers aren't instantaneous. If my math is right, it would take a 24dB/octave to the a 10dB resonance peak at 8.8kHz to ~1% distortion. Don't know what crossovers they use, but 24dB/octave is uncommonly high and I don't know where their 5" mid or 8" woofer rings. I forget what NHT uses on their metal 6.5", but I do know they cross it over at 850Hz for this very reason, then move frequencies above that to a 2" dome. On Xd, NHT uses a 110dB/octave digital crossover at 2kHz to cut out a 5kHz breakup mode on a 5" magnesium cone. A lot more effective than a passive low slope crossover."
Here's the thing, wouldn't this apply to all speakers then? If Axioms are brighter than other companies designs (aka, Rocket) if such a hard crossover is isn't implemented then the Rocket's would be "bright" too which is what I don't get.
Also Edster922 of the board talks about how Ascend posts all kinds of measurements (FR response, decay graphs) on their website. Do you think other companies, like Axiom, should do so as well? If decay graphs of Axioms would be made publically available, this would certainly dispell any "cone resonance" theories.
