Why filter anything from your megabuck stereo. The idea is to get it all. Set your vinyl rig up correctly and it will sound fine with no additional band-aids.
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.

Well everyone has an opinion of course. Perhaps some might be interested in Harry Weisfeld's; he probably knows a bit about vinyl. Then again, maybe not? http://db.audioasylum.com/mhtml/m.html?forum=vinyl&n=1041937&highlight=subsonic+HW&r=&search_url=%2Fcgi%2Fsearch.mpl%3Fsearchtext%3D Sometimes (actually many times) woofer pumping will not be the result of poor setup and sometimes (actually many times) a good subsonic filter is a very good idea. You won't "hear" negative results with a good subsonic filter-quite possible though that you may hear the positive results of not having your woofers flap around in ways that they were not intended to as well as having all the power sucked out of your amplifier by the subsonic frequencies. I'm sure there may be bad subsonic filters out there. The KAB is not one of them (IMO), having used it. I also like the subsonic filter in my phono preamp. |
Dear Hdm: ++++ " he probably knows a bit about vinyl.... " +++ probably yes but I think he knows more on TT/tonearms and IMHO he is not so good on the subject onh this thread. It's an opinion with huge negative trade-offs. ++++ " You won't "hear" negative results with a good subsonic filter... " +++++ maybe you can't but I can tell you that many of us can hear it. Of course that if the audio system has a poor resolution or our ears are not trained then we can't be aware about. Now, if you are happy with then good for you. Regards and enjoy the music, R. |
Raul: The subsonic filter on my phono preamp is -9 dB @ 10 Hz, -18 dB @ 5 Hz and -48 dB @ 2 Hz. Not sure what you'd be hearing down there (at least in terms of anything good on the vinyl as opposed to the negative effects of both the amplifier and the woofers trying to reproduce it), but if you are, you are a better man than me. My system is reasonably resolving, does not suffer from a tonearm/cartridge mismatch and my ears are pretty well trained after 35 years in this hobby. Now if you are happy, then good for you too. Enjoy the music as well. |
