I am stunned. I know my used RM-1's were the bottom tier in 2001 but wow. I finally got em dialed and was listening to Roger Waters amused to death CD and it was just plain incredible. Big baffles don't image eh? These do. In this recording there is a TV set playing to the left that sounds like its about three feet outside my left wall. I have to close my eyes so my brain doesn't go crackers. The rest of the CD is flat amazing. I can't imagine what it sounds like on the other VMPS speakers, but I will know soon. RM-30's here I come! Words cannot explain how emotionally replete a human can be when the sonic picture and the music is just right.

I have been using cuts from "Amused To Death" for many years on the VMPS in my Demo and Reference cuts.

The detail of the ribbons and the way B, builds the x-overs is why they sound so good with that particular CD.

It is recorded in Q-Sound and the technique uses a variety of phase relationships to fool the ear.  The "minimum phase" performance (VMPS = Veritone Minimum Phase Speakers) of your speakers is also contributing reason it works so well.

I don't think this is the reason: I had very strong Q-sound effects when the mid panels of my 626 were wired out of phase.
I think that the speaker setup is very important to get Q-Sound effects. For instance, I listened to Big B 's RM-40 a year  ago, and there was no Q-sound effect!

I really like "Amused To Death" too.

Hi Bruno,

Strangely enough the fellow who invented Q-Sound was also working later in the fitness business, and we spent some time talking about his invention several years ago.

If memory serves me correctly he said it was produced by a combination of phase, delay, and amplitude signals.

Likely the reason your 626's worked with it "even" when wired "out of phase" is that the amount of the Q-sound info coming from the panels and its wide frequency band was "in phase" through the important ranges to produce it.

For it to work well, one must be "perfectly" between the two speakers so that the amplitude differences are not affected.

I would wonder, why you didn't get the affect with B's RM40s.  Were you in the sweet seat?  If so, it should have been as good as it gets, according to Lowe's instructions if I remember them correctly.

In any event, it got mostly shelved when 5.1 was able to produce a similar (and better)effect through more speakers.

It continued to develop more for computer games, and may still be used more for that purpose.  Sure had some interesting effects.

I was in the sweet spot. B's room was acoustically not symmetric: on the left side there was the rack with the electronics. Furthermore, the RM40's were quite close to the side wall and, as far as I remember, there was no acoustic treatment for the side reflections. I suspect that this is  the reason for the lack of Q sound effect.
