Question for the theater fanatics - continuing tests of my new fusion 12 tempests (front left/right) and fusion 8 alchemy MTM center. When running test tones and walking around the room there are noticeable/audible increases and decreases in volume (easily 5 to 10 db on my decibel meter at various positions). I've taken measurements 5, 10, 12 feet away from the speakers and across the ~18 feet of seating with consistent variations. Are these speakers more susceptible to angle and placement or did i just screw up the cabinets (didn't buy Erich's flat pack but will next time)? If so, what's the proper location/angle respective of the prime listening location/duke seat? I thought i read toe'ing the front left and ride towards the prime listening spot so they are toe'd in right now. I also had to place my center in front of the entertainment center and angled up towards the duke seat because it's too large to place inside (next upgrade coming sooner rather than later to get this under the TV)... I still have some breaking in to do; been running a 30hz tone through them but can definitely tell the woofers need some love to loosen up a bit. Hope to have my amp and Emotiva UMC-200 up again next week to truly push these speakers; right now it's my old paradigm vsx-47tx. Thus far even with my old receiver these speakers will blow my ears off if I crank it! Love it; my Paradign monitor 7's stand no chance against these even with my old receiver!
