Looking for advise about subsonic filters. Is the KAB RF-1 the only decent production product available that can be added to the system?
I have woofer pumping problems on some of my vinyl , especially near the beginning of the disc and , of course , especially when there is some warping. I do run ported floorstanders with a sub and have paid a lot of attention to isolation , so I don't think I can improve much in that area.
Anybody have a good one lying around or know someone who can make a good and transparent one for a reasonable price? Otherwise I will probably buy the KAB unit.
