Woofers Gone Wild


Rega P3 with 301 arm/Sumiko BPS III. Even at lower levels, woofers in my B&W 803's are going nuts, flopping around all over the place (and I would imagine, sucking up lots of juice in the process).

Is there compliance mismatch here? From what I can tell, all should be well within the desired range. But still the woofer action.

TT is equipped with Black Diamond Racing footings, and is well placed. All adjustments on table checked/rechecked.

Am going to have a beer and not think about it for a while. Any others with this situation, or any solutions out there?

Thanks for any help,

Doc

I agree with the above post. Filters are useful, but they do filter, an Hi Fi is about running it all out , or as close to the performance limit as possible. Plus this does not remove the sonic problem in the system , just removes the results of the problem. Same as painting over a garden window with a view you don't like instead of doing the yard work.

It could very well be a straight mechanical problem, a compliance mismatch with the cart and arm. If this started with a cart change, or any other change , well it doesn't take Sherlock to come by and point out a few things. If your beer is empty by now, this has already occurred to you. Acoustic problems could also be in play, and are easy to finger, but tougher for some to understand.

I would point out that the more modern resonance understandings take the limit up a little higher than the above poster recommends. If my recent reading is correct to 15hz is the new deal.
