Hello all,
My question concerns subwoofer set-up and phase. I have an HSU-VTF2 sub and a pair of Axiom M22’s for stereo only listening. In the VTF-2 manual it suggest to play some material with bass and to set the phase wherever it gives the most output. On my system this is at the 180 degree setting. Recently I have purchased a set-up disc and a
Rad Shack digital SPL meter, and then printed a copy of the corrections for the meter off of HSU’s site to properly set up my system.
I mean, why spend all this dough and not do it right, right?
After taking NUMEROUS readings, moving everything everywhere, the best I could get my settings were
20Hz-77.5dB,
25Hz-79,
31Hz-82,
40Hz-89,
50Hz-72,
63Hz-83,
80Hz-80.5,
100Hz-82.5.
I realize I have a room node around 35Hz, and a suck-out around 52Hz, but I felt that I should be able to get better readings. So once again I get everything ready to take a few more readings and try to improve on my past endeavors, when I get the bright idea to switch the phase to 0 and see what happens. Within 3 readings I was able to come up with
20Hz-83.5,
25Hz-82,
31Hz-82,
40Hz-81.5,
50Hz-77.5,
63Hz-80.5,
80Hz-80.5,
100Hz-85.
My reference level was 80dB for all readings
My question is, will running the sub @ 0, degrade or “muddy” the sound, one note bass, even though it flattens the overall response?
Sorry this is long, and thanks guys.
