Hello

I'm hoping for a bit of guidance and/or suggestions on making adjustments to a new Center Channel speaker. I've got a older Boston 9000 Micro system that the center channel finally gave out. I ended up up replacing it with another Boston...the A 225C...

Yes... I know it's better to have all matching fronts but with the wife being laid off recently I was lucky to get a replacemnt plus a new sub. I made all the hookups and ran the "Auto Setup" with the Yamaha RX-V671. It's a straight 5.1 with all small speakers. at first the sub crossover came back at 120Hz and I've bumped it to 100Hz. But the results with all the speakers have left me puzzeled mainly with the Center. Here is the breakdown...

Center Channel
Band/Gain - -1.5dB
Freq/Gain - 16.0kHz
Q/Gain - 0.500
Level - -3.5dB
Distance - 7.5 ft

Fronts
Band/Gain - +1.5dB
Freq/Gain - 49.6Hz
Q/Gain - 2
Level - 0.0
Distance - 10.7ft

Surrounds
Band/Gain - -0.5dB
Freq/Gain - 396.9Hz
Q/Gain - 0.500
Level - -2.0dB & -3.5dB
Distance - 9ft

Front Speakers -
Boston Micro90X
Response Bandwidth - 19880.0 Hz
Crossover Freq - 3800Hz
89dB
15-125w

Surrounds
Boston VRS Micro
120Hz - 20kHz
89dB
Crossover Freq - 350Hz
15-100 W

Center Channel
Boston A 225C
65Hz - 25kHz
89dB
Crossover Freq - 2,500Hz

I'm not sure what's up with the Center on the results? I may try re-running the YPAO again a few times and check the results. Besides the Center I'm sure i can tweak the fronts and surronds. If it matters the sub specs are 35Hz - 150Hz. I"ve got the crossover set at max and the volume at halft via LFE connetion. Thank you for any help.
