Hello,

I recently received a 12" btl. I put it in a well built box (I have pics in the build log section), on a Sundown saz 1500 amplifier.

I had a weird noise coming from the speaker at my max volume. Even if I did not change any settings from my previous setup (I had an xcon 15" on it with NO problem), it seems that my gain was too high.

I turn it down and everything is good now !

But I want to find good sounding test tones to set the gain right on the amp.

Can somebody show me where to find some ?

I think in the 50 to 60 hz range.

I set the gain by ears, and I will try to see what I can do with a DMM for that.

Thanks in advance.

Go to the tech section on this site. There are one minute test tones from 20-100hz.

I got them all !

I hope they're at the right volume.

I need a blank cd now. I know I will find one at my co-worker's office !!!!

Thanks again for the link.
