Home Speaker Asylum

General speaker questions for audio and home theater.

Re: So, what was the earth shattering VMPS news? nt

Thanks for the kind words!

Yeah, the RM/X didn't need any hard core work. You sent me as a free upgrade a replacement passive radiator set painted with glue.

But remember my RM-40s with the planars drivers that would either not work at all, or cut in and out constantly ? I had to remove eight drivers from my new speakers, dremel off two aluminum rivets from each to replace with hardware you sent me after about six weeks, then resolder the wires back on. Then I find out later from the dealer that some of the panels just may have had the wrong impedance... after checking with a multimeter and finding about half were different than the others, another whole set of drivers was sent so out went the old ones and in went the new ones.

There was also a woofer whose surround fell off after a few months of light use, but that was fixed with Elmers glue and a cast iron frying pan of appropriate size. No big deal.

My amateur measuremements may not be gospel but they did demonstrate some problems with the speakers -- like absent deep bass below 35hz and major cancellation issues between driver groups. And depending on how they were positioned a hole around the bass-mid crossover point. My new speakers (which were $35k -- definitely a luxury purchase) don't have these problems with the same measuring equipment and room. But neither do some much less expensive speakers that several former VMPS owners now have.

Maybe I should have taken you up on your in-home visit offer. But there is only so much that can be accomplished with micrograms of putty on a passive radiator and 0.1dB L-pad adjustments.

The letter I sent to John Casler expressed the opinion of many other VMPS owners, not just myself. I've owned many other good speakers besides VMPS, most of which I have fond memories of and still would recommend to others.

But I am just a nasty, paranoid, turn-with-the-wind, scandalous, foolish man of science by day, audiophile by night. Don't worry I won't publicly comment on my VMPS experience any more. I curiously await the substance of your new invention.
