For its award winning RM40 speakers, VMPS uses Sonigistix planar ribbon panels that are extremely similar to the the Monsoon computer multimedia panels. For a full discussion see the thread Dual planars for $108 shipped on AVSForum, or do some searches on Harmonic Discord or maybe a picture of a...

I used Brian Steele's spreadsheet to design the size. The BASSIS bass EQ can supposedly provide a 25 dB boost (no lower than 15 Hz), plus it can dampen by a few dB too. This gives me about 30 dB of potential EQ, which is enough offset five octaves of -6 dB/octave drop. It actually drops off at a...

Here is my design, submitted for your critique... Arctic Ice You are looking at front and side views. The black section on top is ribbon, the circle in the middle is the woofer, the baffle is acrylic, and the black box at bottom is the amplifier (not actually part of the speaker.)...

The Marchand XM1 crossover is a "Fourth order constant voltage design (Linkwitz-Riley alignment)." The website claims:

There are a ton of possibilities. Probably it's a combination of a cheap sub that's putting out higher frequency noise and your high crossover that's already directional at its start point. Another possibility is related to room size. The frequency range where bass becomes directional is a...

I tried what I said above, 5 identical speakers, each consisting of a Monsoon MM-702 package, and it actually works surprisingly well. I stacked each pair of ribbon panels vertically. Each 16" composite ribbon then gets put on a woofer box, which also amps itself and the ribbons, so I use the...

1. Using a Radio Shack sound meter, make sure you're not running your subwoofer above the proper level, and back it down a little from the proper level. 2. Get a monster sub if you want, but get a sub graphic equalizer to tame the lowest frequencies (and any boomy frequencies) while you live...

I've searched for and read the previous subwoofer threads, but my problem is somewhat unique. I'm getting 5 identical speakers that lack bass, rolling off at 166 Hz (-3 dB). I'll probably add woofers to them eventually. For now, I'd like to crossover to my subwoofer at 200 Hz, or maybe a...

Martin, why not Y?

I have joined the DA4ES fold. My previous receiver was a Kenwood VR-407 from a HTB-503. Bass management: Yes, you can set the crossover from 40-200 Hz in 10 Hz steps for each of the following: Front, Center, Surround, Surround Back, and LFE. Pre-outs: I bought the thing excited that I...

I just had a crazy idea. How about five Monsoon / Level 9 / Sonigistix MM-702 computer speaker systems? You can get five MM-702's for $540 from Dell, and that includes free overnight shipping (offer expires Monday.) Each includes two extended midrange planar speakers most similar to those in the...

I'm trying to find 5 identical speakers to use with my RPTV. My plan is to place the center below and angle it up at about 7 degrees to point at my listening area and probably do the mains likewise. The bottom of the screen is at 24", though I could raise it. Candidates: $3800 = 5 x VMPS...

Rick, your set does the squeeze, so you should set your DVD player at 16:9 and leave it there. If the people look too thin, turn the vertical squeeze on (anamorphic "enhanced for 16x9".) If the people look too fat, turn the vertical squeeze off (nonanamorphic "letterboxed for widescreen".) Or...
