Dedicated 2 channel mid-sized listening room converted from a spare bedroom. >90% of the acoustic treatment is made with cedar and pine as fun DIY projects built over the past 7 years.
As of September, 2025:
Front wall, part of back wall and both side walls have DIY sound diffusers based on Tim Perry's (Arqen) fractal designs (http://arqen.com/sound-diffusers/).
Ceiling above listening position treated with DIY two-dimensional QRD diffusers.
Center of back wall treated with DIY two-dimensional QRD diffusers.
Back closet contain 4 DIY Diaphragmatic Absorbers based on Acoustic Fields "Acoustic Treatment DIY Build Plans" (https://www.acousticfields.com/) and available online diagrams of ACDA-10 & 12.
Ceiling in the front of the room is angled to minimize parallel surface areas and front side walls covered with standard 48x24x2 absorbing panels to eliminate flutter echo.
Floor is covered with regular carpet, but I use wool rug in the listening position to minimize 1st reflections coming from the floor.
All equipment is supported by different types of vibration control devices.

In the world of Virtual Systems on Audiogon, I’m astonished this system only has 330 views over the course of the past two years. Favorited months ago and something to strive for, especially in respect to DIY room treatments/diffusion. Great pics as well!
