Anyone wish they had a rumble subsonic filter?

Hello, I use a 20hz filter which I believe is necessary for any LP playback system. Since my system is very capable of reproducing low bass I also use a rumble filter which monos the signal at 38hz. 180 hz is too high to sum to mono. Try the 20hz filter first then if you still have a problem you may need a rumble filter. The two types of filters are for two different problems and 20hz is the first one to address.

This all depends on your system and its bass reproduction abilities ie: tonearm/cartridge and table interaction and its bass reproduction and your speakers ability to reproduce low bass. I think stereo reproduction is important to at least down to 50 hz and lower if possible.

My 20hz filter and the rumble filter are in the Marchand Bassis.

Hello again, I think the Marchand Bassis is a great unit. Mine is set up after the Marchand XM126 crossover so only the low freq go through it. It has a 20hz filter and a rumble filter of which I find both to be necessary. Also the Bassis eq is very subtle and I believe would be a wonderful addition to your system. It only extends the bass response where your system starts to fall off and you can correct the Q and the bass extension. It works with ported and non ported speakers but is most effective with non-ported. As far as additional equipment and interconnects remember as Einstin said to make things "simple but not too simple". Well here is your solution for several problems, of which, for the most part you are unaware of untill you hear it. You do have rumble and subsonic problems, and they do need to be eliminated. Musical reproduction is like the universe, you always know there is something more out there....

PS thanks for the compliment on my system. I consider my system minimalist as it only has what is necessary for reproduction of vinyl music. That includes the Bassis which, if you understand it, is a great piece of equipment and is quite reasonably priced. I recommend that you buy it with the stepped attenuators rather than the pots if you do indeed buy one.
