I have SERIOUS problems with this statement:


Less than .9% from 10 Hz to 240 Hz @ 95 dB SPL"

That has to be the average taken from the 10 Hz to 240 Hz passband.

To me you have 2 VERY misleading representations here:

1. That the output (95 db here) is similar regardless of freq. (i.e. suggesting a reasonably "flat" response from 10 Hz to 240 Hz.)

2. That distortion is less than .9 percent at lower freq.s in that 10 Hz to 240 Hz at 95db.

In other words while it may be less than .9 percent at say 100 Hz at 95db, what is both the response and distortion like at around 20 Hz? If its less than 5 percent (2nd order) at 20 Hz at 95 db I'd be astonished - even then THAT would be excellent when compared to most designs.
perspective is everything
