High Pass (Brick Wall/Rumble) Filter Suggestions


Hi Folks:

I'm interested in trying a high pass filter to eliminate any rumble, vibration, feedback from getting to my table. I've seen the KAB RF-1 http://www.kabusa.com/frameset.htm?/accesss.htm and have read the reviews (which are favorable) but wanted to see if the community had any other recommendations. I want to make sure that I'm not losing anything or altering the rest of the frequency response by using a filter to take out everything below 20hz. Thanks for your suggestions.

OK, ordered the FMOD from Harrison and will give it a try. If it works I can see whether the KAB offers better performance for a bit more scratch. Thanks as always everyone!
Just so you'll know, the Fmod filters are only 12dB/octave, not exactly "brickwall" !
I use the KAB rumble filter with my VPI Prime.  It works as it should and does not decrease the bass or dynamic range.
