Re: First real measurement subs, subs+main, subs+main large


The critical band is between 100 Hz and 5 Khz. Below 100 Hz is not very important and even high Q room resonances tend not to be audible. The measurements above 100 Hz should have high Q resonances damped out or notched out.

The best way to handle room LF's is to use more than one sub, experiment with placement and phase settings.

If you can put 3 subs in its unlikely you can experiment with placement much but you can exoeriment with phase settings.

If you can take 8 shots then do this.

(1) sub1 = 0 deg sub 2 = 0 deg sub 3 = 0 deg

(2) sub1 = 0 deg sub 2 = 0 deg sub 3 = 180 deg

(3) sub1 = 0 deg sub 2 = 180 deg sub 3 = 0 deg

(4) sub1 = 0 deg sub 2 = 180 deg sub 3 = 180 deg

(5) sub1 = 180 deg sub 2 = 0 deg sub 3 = 0 deg

(6) sub1 = 180 deg sub 2 = 0 deg sub 3 = 180 deg

(7) sub1 = 180 deg sub 2 = 180 deg sub 3 = 0 deg

180 deg = reversing connections.

See which one gives you the best response.
