    If you are good I will take a photograph of the matching cushions!
    I am very impressed with the sound quality though ,oddly it is the mid range that is subjectively at least improved, voices are absolutely stunning, bass is more defined ,just all good, I will measure this weel and compare to the pre Modex measurements.
    The question is now of course will more panels improve further?

    Re: RPG Modex™ Plate

    Two more Modex plates arrived yesterday, I have been using REW's test tone generator to examine the 'problematic' frequencies inmy room, it has been fascinating.
    A 57Hz node caused by my ceiling height, it causes a shallow band of reinforcement at floor/seating level, stand up slightly and it disappears!
    Well worth experimenting ,but remember don't play the tones too loudly or you risk damaging your loudspeakers.

    Darn it! I wanted to send a picture of my Modex Plates, but I don't have enough posts. I need to get busy

    Keith,
    Did you place your speakers in the corners?

    Re: RPG Modex™ Plate

    Keith,

    Have you found your pressure zones to help with the Modex Plate placement? I found mine were mostly high and at wall intersections.

    Re: RPG Modex™ Plate

    Dallas the speakers are on the large side, ideally you also need to sit 4-5 yards away ,I only had two placement options, one of which would have been in front of the bay windows.
    So not much choice regarding placement, Scott I use a room node calculator the Huniceke ?
    one if you google room node calculator it is there.
    Entered my room dimensions and then used the frequency generator in REW to help confirm the main nodes, floor ceiling 50Hz still an issue but I have orderd some 50Hz specific Modex
    corner/modules, I have been hugely impressed with the Modex plates.

    Re: RPG Modex™ Plate

    This is a pretty old thread, but I'm interested in how the RPG Modex absorbers have held up/aged over time, specifically are you all still happy with the performance or have you moved in a different direction?

    I have some nasty room modes at 33-46 and 50 - 80. I've done a lot of treatment to knock down the worst of them and in my primary listening position, using 4 Swarm subs, the bass response is quite good (~4 dB range from 30 - 100 Hz). I do most of my casual listening seated at the side of the room working at a desk, and the bass is pretty lumpy there, which is why I'd like to tame the standing waves.

    I have room for 2 Modex traps on the back walls. Would 2 make an appreciable difference? Given the Modex seems to sell for around $2k per, would I be better off with active bass management like th PSI AVAA, which at $2500@ would cost $7500 to treat the whole room (assuming PSI's claims are correct)? I can also add some corner traps at the wall/ceiling interface, but again, at $500 per is this needed?

    Thanks,
    EVan

    Re: RPG Modex™ Plate

    My Modex plates have aged wonderfully. I still love them. When I got rid of my Raidhos I didn't need the all of the corner RPG treatments I had put in. But I've left the wall plates.

    Thanks. I'm having a little difficulty getting a quote, but from other places it seems the RPG Modex plates sell for ~$1800 each. Worth it if 2 panels will make a noticeable difference in my bass response. If I need more area maybe I'll go the AVAA route (although I'm having trouble getting any order information from PSI as well).
