At times I use/play a Denon Audio Technical CD just to check that my system "sounds right". This disk as a number of tracks with sample music that covers the entire gamut of frequency range, dynamic range, imaging subtleties, etc. www.cduniverse.com/search/xx/music/pid/1...dio+technical+cd.htm

The disk also has specific "spot frequencies" (a single frequency sine wave, 0db). How loud and for how long can one play a spot frequency before damaging one of the driver (meaning any driver, woofer, midrange or tweeter). I realize that common sense dictates to play at low volume for short periods of time. However low volume and short periods of time is relative, and can differ from one persons opinion of what is "low volume" and what is "a short period of time".

I'm wanting to play low frequencies at high volume (greater than 80db) to gain a sense of what if anything resonates in my room. I'm wanting to play very high frequencies to determine if I can actually "hear" it. But I'm wanting to do go loud (90+db) and long (more than 10 seconds). In your opinion(s), could I "safely" do that (i.e. not risk damaging one of the drivers).

@moderartor, I'd appreciate your opinion in addition to other forum members.

Thank you all in advance.

Hi GDHAL, Playing very low and very high frequency test tones at loud volumes for extended periods of time is a good recipe for how to damage a loudspeaker. I would not recommend trying this. When playing test tones on home audio equipment, I would suggest keeping the volume on the lower side (80db or lower) and for short periods of time (a maximum of 10-15 seconds). Most electronic gear and loudspeakers are designed to play music or soundtracks that vary in frequency and volume level. They are not designed to play steady test tones at loud volumes for extended periods of time.
