Get a KAB rumble filter for 189 and problem is solved. I had the same problem with my Scout turntable, I tried relocating the turntable to various locations and using all kinds of platforms under the turntable and nothing helped. Put the rumble filter on the tape loop and use it when playing records. All the oscillating speaker problems will go away. I hear no difference with the rumble filter in and out of the system. The only thing that changes is the woofer pumping: none with it on and all with it off.
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.
