Hotsauce, Is rives audio selling these resonators? I dont see it in their website. However, I do see that virtual dynamics is selling the acoustic resonators by Franck Tchang.
Tbg, maybe I do understand why u cant stand Rives design. I did a Level 1 with Rives audio. I like the look of things but the detail drawings could have been better. I have to ripped off the front resonator due to vibration which I constructed as detailed in their drawings. However , to be fair to Rives audio, Richard in particular, he was very accommodate in entertain my questions when I was faced with a blurred image issue. So for those using Rives audio, asked as many questions as possible and use some creativity in constructing the room treatment. As far as room treatment and design is concern, I believe there is no 1 right way\ only, just like how synergistic research and acoustic resonator approached the room tuning issues using different products and materials.
