Does anyone use a RUMBLE filter?


I am having way to much cone movements on my main speakers and Sub when I play vinyl. Someone suggested I purchase a rumble filter from KAB audio. I notice that a lot of the cheaper phono preamps have these filters built in. When I purchased a more expensive better sounding unit ..it dosent have one. So I am wondering why dont a lot more companys sell these things if they are so important? I need to buy one and they dont seem to be very expensive $170 + another IC cable.

Rumble is one form of low frequency noise produced by turntables themselves. USing a good table ( I prefer belt drive) and keeping it in good working order goes a long way towards minimizing any impacts from rumble these days, it seems.

Warped and poorly cut and centered records are another common source of low frequency noise associated with vinyl record playback.

Resonance inherent in all turntable systems compounds the problem to various degrees depending on setup.

I've used high pass filters in the past on occasion to reduce low frequency noise associated mostly with certain vinyl playback cases, and tapes as well to a lesser degree, but low frequency noise is not a noticeable issue for me currently with any source I use, including vinyl. So I no longer use one.

Part of this is because the drivers in the speakers I use mostly are enclosed in a metal mesh can and abnormal incursions can not be seen, only heard. They handle whatever is thrown their way effortlessly and there is never any sign of audible stress to be detected.

Not the case as much with my smaller monitor style Dynaudio speakers, but even those handle most things fairly effortlessly.

Another part of this for me is I use a very robust and powerful amplifier these days that has plenty of dynamic headroom available to help effortlessly handle whatever is thrown its way.

I also have an even smaller pair of Triangle monitors. Those are much smaller dudes and will tend to show signs of any stress a lot sooner than the other bigger boys.

Rumble used to be more of a problem for me years ago when my system overall and turntable specifically was of lower quality and not as robust and resistant to effects of low frequency noise associated with vinyl playback in general.
Dear Lewm: I know that you will be pleased when do it the same on your great Sound Labs.

Regards and enjoy the music,

Bottom line here is... What I have found is that proper cartridge and tone arm matching are essential in almost eliminating woofer pumping. Having said that, you can never get rid of it because it is part of the record/vinyl and every record sounds and acts differently, some I think were cut very well by a real craftsman with the proper tools, others are just really bad examples of the art. I want to thank everyone for posting I see I struck a real dark vien in the audio world. LOL, happy spinning and lighten up ok its a hobby!
