Hey guys. I've recently upgraded my PSW350 to an SVS 20-39+.
My current set up is:
I'm trying to find the best spot for the sub and have been doing some frequency plots on it using test tones.
Things are very smooth except for one problem area.
For whatever reason, I get a substantial db loss between 80-100hz. I've tried different placement issues and that effected the curve, but there wasn't a placement that helped that gap.
I have the receiver crossed over at 80hz, the sub's crossover set to "disabled" and turned to 120hz just to be safe.
I did notice that when I changed the phase from 180(which was the proper setting for the polk sub) to 0, that I gained about 8 db in that range. But the dropoff still seems sharp to me. Is there an intermediate step that would be better for me to set the phase at? Obviously it's a dial so I can put it anywhere between 0 and 180. What have other RTI/SVS owners found to be ideal?
If you could take a look at my frequency response graph, I'd appreciate it.
Of all the spots I've tested, this really seems to be the best in terms of low end oomph, and flat response...
I have the digital RS meter and applied the correction factors... I'd been told they were the same as the analog.
