Need Help Subsonic Filters, where can I get one?

A good deal of LP rumble is not "subsonic". Although a subsonic filter will prevent your amplifier power being wasted, it may not solve the audible problem you are having.

You might consider the Audio Control Richter scale (several hundred dollars) which has a good subsonic filter, as well as a 1/3 octive equalizer covering the range from about 150 Hz down. It also has an electronic crossover section, in case you ever want to biamp, or subwoof.

Buscis2...I agree that a rumble filter and/or a LF equalizer like the Richter scale, is a "bandaid". So is the use of expensive vinyl playback equipment. So, for that matter, is the RIAA equalization curve. Bandaids are often practical.

However, to really fix the root problem of LF noise you need to adopt digital discs or tape. (This would not be necessary if DBX LPs had caught on).

INCOMMING!!

Buscis2...As you will note (by reading my comment) I think that the best thing is to avoid the problem. I don't eat much vinyl. But when I do, my rumble filter avoids distress.

Buscis2...I gather that you still have DBX encoded records. All my objections to the vinyl medium (well almost all) are put aside when we talk about these discs. I no longer have them, but when I did I thought that they were as quiet and as dynamic as digital discs. A bloody shame they died.

I guess I would categorize DBX encoding, like RIAA equalization, as a "band aid" on the basic recording media, but a very effective one. To extend the medical analogy, if the symptoms are completely relieved, you really don't need to cure the disease.

Davehrab..."INCOMMING" suggests that I am prepared for a violent reaction to my comment.

The fact that Ivan did not nuke you over the last few decades is due in no small part to the fact that the Fleet Balistic Missile program was an awesome deterent. My job was to guide the missile to an intended target, so that the destruction would not be "mass".

We had a story that we told new employees. In the USSR there is a missile base with weapons aimed at US cities. Five miles from the missile base is a school for Russian girls. It is filled with 18 year old blonde beauties. Our job is to make sure our missile hits the base, not the school.

In a larger sense, we always knew that if our systems were ever used, our program would have been a failure. Thank God we never had to launch one in anger.

That would have caused phono pickups to bounce off records for miles around. Terible!

Sorry. You need Top Secret security clearance :)

Buscis2...18 year old blondes, Analog audio...been there done that. And moved on.
