Dual subwoofer gains - SVS SB-3000 Revolution
Any of you have dual SVS-SB-3000 Revolution, or maybe just dual identical subwoofers? Are your gains, before AVR room correction, on both subs the same for the same SPL at equal distance? One of my subs seem to be much weaker than the other. I have to increase gain to more than -10dB for it to sound loud. The other sub sounds loud and impactful with just -15dB. Even putting my ear right next to the driver I hear the difference. I got both subs at the same time and both came in pretty beat up boxes. I think I should exchange the one that sounds weaker and doesn't produce strong bass like the other one. When I ran autoeq, both seem okay though.
Update: I think I resolved the issue. Looks like the surge protector / power strip I used for the two subs were to blame. I saw the load warning light blinking (APC SurgeArrest P11U2). After I removed the surge protector and put the subs into the same UPS I have everything else connected to, they both sounded much better and more even between them. If I didn’t see that warning light I never would have figured this out. The sub never shutdown or did anything other than sounding uneven and not having the rumble and impact.
