Looking for a subsonic filter.


Any suggestions.

Harrison labs sells a 20Hz filter I used as a subsonic filter for a turntable. Price is not bad at $24.50 for each channel.

Is this for a subwoofer or turntable use?
Thank you both for the quick responses. If either of you have used them, I'm curious about their effectiveness. Both are passive, but one is 9 times the cost.

Thanks again;
Gentlemen. Thank you all for your advice. One more question. Does it matter where in the signal change the subsonic filter is placed. Your input is much appreciated.
If you have to use a rumble filter, the best place to put it is between the phono preamp and line stage, IMO.
