Ok I'm connecting the sub with the Spkon cable and all three leads to the back of the amp, Otherwise wont the amp then SEE the REL in the system? Before I got the new table I had been using the REL for quite a while with no problems ever. The REL is plugged in to the wall using a 3 prong cable (both the spkon and power cord are from Signal Cable). I do see the woofer pumping on the main speakers too, and this seems to occur more toward the outside of records im playing. The Sound is very very good. If that says anything. But this cone movement needs to be addressed. I'll do a little more troubleshooting and get back soon. Do a lot of vinyl spinners use outer rings?? I see that most of the HIGHLY re guarded phono preamps Don't have subsonic filters? Like my MS Phonomena. I don't think my phono stage is the problem. I respect every ones input thank you. Stereo5 you sound like my older brother..LOL that's what he keeps telling me. He has a KAB. Yogi, Wouldn't the sound be bad or unpleasant with a bad arm/cart combo? because the sound seems to be gorgeous! Al, Im using unbalanced cables to amplifier and my speaker cables are spades, the REL Spkon cable is Bannanas on amp side. I have a concrete floor with carpet. Salamander rack with Mega spikes. Yogiboy, I think is on to something, but the sound is so dam good? So I am perplexed.
Woofer pumping WHY??
Hello All, I have an older REL B2 series. I love this sub. I recently received a new Project Xtension 10 with Clear Audio Maestro Ebony v2. After a couple days I noticed bad woofer pumping on several records I like to listen too. When I brought it up to Needle Doctor they told me it was my records and said it worked fine in there store. Now my REL is blown! I am so upset at myself for not taking this matter more seriously. Now I am purchasing a KAB rumble filter because I am not going through this again. Is this a cartridge mismatch?? Because on my REGA with Dynavector 10X5 It did not do this woofer pumping nearly as bad. AND I do remember putting a DENON DL103 on my RB301 and this same woofer crazy action occurred!! Immediately took it off that arm. I just spent $4100 for this Xtension10/CA Maestro and now I am scratching my head. Hmmmm.

Mattmiller,I standby that the cartridge arm combo is not a good combination,and will wreak havoc. The sound is good because the problem is in the subsonic region that you will not hear. If you don't address this you will have the problem till the cows come home. You should get the filter if you think that will work and return it if it does not fix the problem. BTW,if the NeedleDoctor tells you there is not a problem then he should go back to med school ! You should get a test record with the resonant frequency test. I use the Shure TTR 115 ERA lV,you can find them on Ebay for about $20 bucks. The other fix is to get a higher compliance cartridge or an arm with more mass. |
Schubert, Ortofon,Grado,and some Soundsmiths all have medium compliance and will work with a tonearm that is from light to medium. I don't think they make super high compliance cartridges and super low mass arms that was the fashion many moons ago. I was kind of surprised that the arm the OP has was only a low 8.5 grams mated with a cartridge with a low compliance |
Hi Matt, had the same problems after my Lyra Kleos was to repair. When i got it back the compliance was softer and i had this pumping. Look here Video The deflection of the needle because the decentered records correlates with the woofer pumping. No i have an EMT JSD6 which a lower compliance and on the loudest volumes no pumping. |
