This is the left channel measurement of my system at the listening position about 6 feet away. I would consider it "in room" response. I made this measurement after a round of crossover tweaking. Note the 450ish distortion and peak. That would be surround\cone breakup. Still about 1% THD there. Would this response be considered bright or what?
The mic is 9 feet away not 6 and is in the middle of the room left to right just behind the rooms center front to back pointing straight ahead. This is a 15" two way with AE TD15S woofer and JBL 2431 tweeter on 90 degree horn crossed at about 800hz. The TD15S is known to have a cone\surround resonance in the 400-500 hz range but doesn't show up at low levels. The 12Khz roll off is all that 2431 horn combo will due. The good thing here is most 1.5" drivers with 3" diaphragms have peaky breakup but this one doesn't. I have Wavecore, Vifa, SB domes and like the JBL best. This is measured louder than it looks. I did drop the tweeter level some when listening last night.
The system does sound bright to me but since its' so clear sounding it's not annoying. Sound stage and imaging are exceptionally good.
I've had this woofer crossed at 400hz to 18sound mids and wavecore highs but this two way combo sounds best to me.
I'll make more measurements with gateing and tweeter crossover tweaks late this week.
Thank you!!
