Thanks millercarbon! When I moved last year, I dealt with an entirely different acoustic/room custom engineered. I did not add acoustical tweaks at first. I started with vibrational tweaks (Stillpoints/Townsend Seismic Sink and Herbie’s tube rings). My friends and I listened. Then we added the SR HFTs. Great, just as in the previous locations as indicated by the SR directions, they worked. Then the front Hallographs, then the rear Hallographs (this took about 8 hours to get adjusted correctly). Then the PPT products. It took awhile, several months, adding even more PPT products than I had in the prior location. Then I discovered that it was a negative addition where there were magnets present. Then I realized that by adding or subtracting certain products I could achieve neutrality across the frequency range with added depth, warmth and openess. So to Jetter, I used my hearing (and seconded by astute friends who are in the business) to make my final adjustments.
