I was testing my speaker levels at 00 db and then just a bit louder, to 03 db. Accidently switched the tt off, and it went to normal cd output. Man was it LOUD. Pressed mute four secs. later, but nearly blew my speakers. There is NEVER a problem with the test tones at that level, but for normal output (eg CD) it is REALLY loud.

I can't understand why/how the absolute volume reaching the speakers would be that much louder on non testtone (eg CD) output.

Am I correct that normal output is louder than the same volume setting using testtones, or is it just a misperception on my part??

I've calibrated my 950 at 85db with the volume set at zero. When I try to play at zero volume level, it is way too loud for my sensitive ears. So, I end up at about -10db for movies and -20db and lower for cds.

The test tones are intended to allow you to calibrate your system so that 0dB is the "reference" level. For most people, actually operating at that level is uncomfortable. In fact, I rarely get above -20 or -18 on TV and CD material and rarely above -08 or so on DVD's.

Points very well taken. Just was afraid that the speakers were damaged...but they don't seem so.

For me, in theater use I use -08 or so, and for music, -14 to -19 or so. I use Polk LSi 80 in walls with the LM-1 sub.
