acoustic system resonators

Peterb, I assume the back wall is behind the speakers. Were I to position these eleven resonators as you suggest some would have to be on windows and cabinets or book shelves. Is that okay? Also those behind me would be behind shelves of records. Okay?

I have tried many room treatments. I have used RPG diffusors, Tube traps, Room Lens, Acoustic Mirrors, Shun Mooks Mpingos, and presently Shatki Halographs, which are the most successful. I have also done digital room corrections which were the worst. I have also used Brilliant Pebbles and Acoustic Revive Quartz Resonators and still have some Harmonix room treatment pucks on the walls. The Acoustic Revives have been very effective on the speaker wall and the windows on it.

I have found great interactions when using several of these devices at the same time. Presently, I can only use one pair of the Halographs, seven of the Shun Mooks, and the few Acoustic Revive Quartz Resonators on the speaker wall. My H-Cat P-12R line stage has a very effective Wave Timing Control that greatly affects the sound stage and realism of the image. I particular the Halographs, Mpingo Disks, and Brilliant Pebbles fight with the H-Cat's WTC. I imagine that the Acoustic Resonators would also.

A Sound Level Meter can determine locations in the room for resonators with better accuracy in many cases than following general instructions or the old "move and listen" technique. YRMV.

I think only a Tricorder can help with this level of complexity;

Shadorne, of course this has been over a 20 year period and usually with one device tried at a time. Once about a year ago, I removed every room resonance device and adjusted the H-Cat. Only then did I seek to reintroduce the resonance devices. If they helped, they stayed.

Tbg,

I figured it was a bit more sane that it sounded in what was a probably a quickly typed response...I just could not resist suggesting Spock take some Tricorder readings ;-)

When setting up a sub for the first time I often feel like calling Scottie and askiing him to beam me up new dilithium crystals....this hobby can be fascinating but it can be a challenge sometimes. Peace ...
