SVS Sub & Yamaha RX-A770---sub very very weak

[Chris Maxwell]

I have a SVS PB-1000 and the yamaha rx-a770. I just switched out forth def tech speakers and that sub sucked but it was working. I switched out the five speakers and the sub with SVS and ran the ypao setup. Everything sounded normal just like when I did it with the def techs.

At first the sub was so weak I could only hear it if I turned the gain all the way up. Then I stopped hearing anything from it and the display on the yamaha that shows L, C, R, LS, RS, and SW now shows all of the speakers except the SW.

I followed all the steps as far as setting gain to 10-12:00 and LFE for crossover etc.

I pulled the cable out of the receiver with the sub on ant tapped it and the sub is definitely responding.

Any suggestions would be greatly appreciated.

So if I go through the manual setup and then turn the volume on the sub to about 70-80% it sounds okay, not great. With the deftech sub I could leave the volume at about 50% which is what I thought was ideal.

All equipment has varying gain structures. As long as you have enough gain you are OK. It matters not a one wit where you set a volume knob. You are worrying about nothing.

I have 2 sb2000 in a room 15x15 and 1070. Both subs are at about 70% gain. This gives me +6db for low end comparing to other channels. At 12 it did not sound good to me.

When you ran YAPO did you make sure your speakers are set to small?
