dB Speaker Ratings - Valid test?
« on: 9 May 2008, 09:00 pm »
I'd like to measure the efficiency effects of adding passive high-pass filters into my system. I can measure SPLs (Radio Shack meter) of mains at listening seat with and without the filters (all with subwoofer off; volume knob stationary). I was thinking of using white noise signal (track from ACI CD). Would this be a valid test? :dunno:

Doh! I forgot about the insertion loss. Never mind. Dumb idea.  :duh:  :duh:  :oops:

And then there's the issue with display reading corrections due to inaccuracies of the meter.
