Having never tried room treatments before, I recently figured I would give it a go. I wanted to get something that was designed for open baffle dipoles, well made and affordable. I own the Triodemasters which are a perfect candidate or actually any Spatial Speaker would benefit. I got a recommendation to seek out the Mr T diffusor panels from someone on the GR Research Forum here.
Below is a grab from the website at PI audio group LLC. ABB1 Mr. 'T' Hemispherical Radiation: 47.5" X 23.5" X 6" - Perfect for open baffle use: Unpainted / Box of 2 pairs (M & F) $180.00 Painted / Box of 2 pairs (M & F) - $220.00
Standard colors are Behr Black and Behr Swiss Coffee. Other colors are available for a small upcharge.Note:
If you want to paint these yourself...I got confirmation you can use a water based paint from your local hardware store. Pink anyone?

So I ordered the unpainted version (4 panels or 2 pairs) and it was shipped very quickly. These panels don't weigh a lot. They are made out of very dense thick foam, very similar to Styro Foam, but much more durable. Greg advised me to place one panel behind each speaker, and align the middle of the panel with the tweeter. He also recommended to cover the tv as much as possible. So because they are light weight, I bought a pair of clear plastic containers to hold up the one panel in front of the tv when going into serious listening mode since my stereo is in my family room.
What I hear with the Diffusor installed: For me in my room it made a very noticeable improvement in clarity. Basically they do not change the balance of your system. What they do is tighten up what you have already. A much more focused soundstage and inner detail retrieval that was not there previously. Since the highs and mids improved they also help out the bass from what I noticed. Bass lines are cleaner and more defined. Highly recommended..not too expensive and I think they look pretty cool.
