The measurement your seeing in the graph is an average of three measurements; one taken at the center prime LP at ear level, the second about 12" to the left of the first measurement position at ear level, and the third about 12" to the right of the first measurement at ear level. I applied 1/6th smoothing to the final graph per REW guide suggestion. It includes Left + Right + Sub. This evening I plan to take some measurements with the sub turned down some.
Speaking of sub level, I don't understand why the sub level is elevated. Using my Radio Shack SPL meter (C weighted, slow response per my processor's instructions) I set each speaker and the sub to 75db. So how did the sub level on the graph end up so hot?
Other than a single PEQ available for the sub on my processor (it's not being used), there is no EQ available/being used in my system. I'm considering adding some kind of PEQ unit for the sub.
My setup is 5.1 that I use for movies and music. Speaker configuration used depends on the content being played and my mood (2.1, 3.1, 4.0, or 5.1). My equipment includes;
Pre/Pro - Anthem AVM20
Amp - Parasound 5250 (5 channels)
L&R speakers - Soundfield Audio Monitor 1
Center speaker - NHT AudioCenter 2
Surround speakers - NHT SB 1
Powered Sub - SVS 16-46PC+ (located in a corner behind the front left speaker)
Sources included CD, DVD, BD, SACD, DVD-Audio, and wireless streaming from my computer via a Logitech Touch.
The room is a living room and dining room combo. Dimensions are approx 14x25 with a cathedral ceiling. The room is open to an upstairs landing and a short hall on the first floor to the den. There's also an open doorway from the dining area to the kitchen. I estimate the volume of the room including the open upstairs landing is about 5500 cubic feet. There are no room treatments, just standard furniture (treatments not likely to pass spousal approval). The floor is carpet/padding over concrete. Here's some pics that may help you visualize my space.

Right now I'm focusing on learning how to use REW and interpret the graphs. I'm considering upgrading my sub; perhaps with a better single sub or perhaps a pair of subs. I'd like to learn how to properly set up and EQ a sub(s) so I can get the best out of my upgrade. A smooth response throughout the room is not a priority since I'm the only one that cares about SQ and 99% of the time I'm in the prime LP (center seat on couch).
Am I on the right track?
