I agree with everything except the "95-110dB for heavy music" Or the 80-95 for "light music" I recommend everyone go out and buy a SPL meter (sound pressure level) and never go above 85db for at home listening. 85db for prolonged use is already enough to cause hearing damage

alvargAgree. I find even 80 dB prolonged to be very uncomfortable. However, speakers should be able to handle peaks 20-30 dB above the average with classical music. Recorded pop music is usually highly compressed, so the peaks and average would be much closer (ie, constantly loud instead of intermittently loud) -- so maybe 10 dB headroom is fine for pop. Also, if you use digital equalization, an amplifier needs more headroom to account for any digital pre-cut. Unfortunately, I can't remember ever seeing speaker specs separated into peak and sustained SPL -- maybe someone that knows something about speaker design can provide some clarification on this? Just wanted to add: 12 dB pre-cut is probably the most needed with equalizing. That's based on my personal experience as well as the maximum EQ adjustment on a DBX 31-band graphic equalizer I own.

alvarg85dB is for average, the SPL levels stated here are for dynamic peaks. Movie theaters typically use THX standards which call for 85dB average and 105dB peaks (so 20dB dynamic range from RMS to peak).
