And if so, approx. how much? At least 3db?
Increase efficiency with high-pass filters?
Would adding a pair of 1st-order passive high-pass (85Hz) in-line filters to my main speakers (rated -3db@55Hz; TMM; M's are 6"; ported) gain some efficiency for me? My goal is to possibly use a lower powered amp. I also use a pair of self-powered subs to fill in the bottem end.
