Home Speaker Asylum

General speaker questions for audio and home theater.

do the math...

3.5W = 5.5dBW Amplifier RMS. Add 3dB for peak power... round up - 9dBW peak. 94dB loudspeaker - both running gives you 94dB in one Watt peak as the listening chair for both speakers - perhaps a little bit more depending on your room. Add 9dBW for the Amplifier clipping point - assuming you don't want your amp to clip. That gives you 103dB peak power - subtract 15dB for typical program crest factor. 88dB RMS level on playback material at the listening seat. Pretty loud for a little amp.
