OK, Another question for you L36 owners. I really like these speakers but I noticed that when playing LP's I am getting some woofer flutter or maybe it is called rumble. It is slight but it is happening. I made sure my TT's which consit of a Technics SL-Q3, that uses a Shure M91-ED with proper stylus and a Kenwood KD-550 useing a QLM MKIII with correct stylus, are set up correctley depending on which one I am useing at the time. After making sure everything is set up correctley I decided to try some cheese cloth, which is very pourus, in the ports to see if it helped and to my surprize it stopped all of the rumble and actually seemed to snug up the bass. Now my question is will this hurt the speaker over the long run or is it safe to do this? I did a search here and could not find any answers so I either missed the thread on the subject or it just wasn't talked about which I find strange. So what do you guy's think. TC.
