Since this thread has been resurrected (and it wasn't me this time
, I'll simply add that my experience with the Evo 4.4 has been very positive. I haven't experienced what I'd call an overly narrow or restrictive sweet spot. And I haven't experienced a bright tonal balance. To the contrary, these speakers have worked well in both my dedicated theater room and my living room.
My theater room is set up for me to sit just to the right of the center sweet spot, but the room has a lot of inherent problems; its long and narrow like a shoe box with lots of hard wall surfaces and a low ceiling. I tried the Revel F36 in there, and the highs were ear splitting. I appreciate that humans evolved in caves, but that room is just too small and reflective for a lot of tower speakers. The Evo 4.4s sound great in there with no broad EQ (bass only via Anthem's room correction) and have no fatigue. To be fair, I have a 7.2.4 setup in there and almost always listen to music in spatial/surround. Many times in the upper 80dBs, too.
My living room has its own challenges as a semi open space that flows into the kitchen and dining room. It's not set up for perfect stereo sound, with even my chair a bit off center. Evos sounded great in there, too with no EQ ( I did cross them over and use a dedicated sub since it's a large space). Since I moved the Evos downstairs, I use the F36s in the living room, and they also sound really good. However, even in that room, the F36s are a touch bright to my ears. I occasionally feel the need to attenuate the treble with tone controls, and I can't tolerate them at 85dB or so for very long.
I can only guess that the smaller bookshelf Evos that Amir measured have that hot treble that seems common in that product market, while the towers don't peak as much and/or have a more prominent midrange that changes the perception.
