Power outage last night, 6.1 subs not working correctly?

[RobO]

So last night we had a brief power outage due to some storms, it was brief so immediately power came back on producing a loud thump in the process from the sound system. It was late so I turn all gear off overnight but booted it all back up this morning. It appears the subs in my 6.1's are not delivering their full power. Checked the AC fuses at the rear plate and continuity was good. Running a brown noise signal at 20 hz - 20 KHZ however rendered only a small amount of output with the gain dial set at 6. In order to obtain what sounded more appropriate I had to run the dial almost all the way up to between 9-11. I have other Genesis 928 subs and they are all fine apparently.

Does this seem normal, or appropriate? Is there anything else such as internal fuses I could check that might have blown? Thanks In advance.

I had a vaguely similar problem with my Genesis Maestros. Power outage and then non-performing subs. Turned out that the bass 'module' that controls the sub had been damaged and required replacement. The electrical shock also blew out the bass drivers, so they, too, had to be replaced. I now get quite nervous when the monsoon thunderheads roll overhead. Gary Koh will be of great help to you, I am sure. You can contact him through the Genesis Advanced Technologies website. Good-luck!

Thanks for the feedback @ChasFreeland and apologies for the delayed response. Got busy with some projects and never got back on this. Sounds like your speakers took a worse hit than mine. The last time I talked with Gary its was my understanding that most if not all repair parts were virtually unobtanium for my speakers given they were discontinued probably over 10 years ago by now. In the meantime I am getting some output from the 6.1's just doesn't seem like its as much.
