HElp with graphs

[usp1]

I measured my room using REW and got the following graphs. The graphs are at two potential locations that meet WAF. Because of the open design plan of the house there is no real space for treatments (besides they wont meet WAF!)

In any case which of the two locations should I use. I know I will need some eq but wanted to know which one curve would be easier to deal with.

The room layout shows the walls (dark lines), the location of the TV and speakers, blue rectangles are the seating with a coffee table in the front, the blue squares with the numbers are alternative locations for the subs. The brownish squares are large book/display cases. The room is 20X17X8.5....the tv is against the 17 ft wall.

The first graph is for location 2, the second for location 1.

ANy comments will be greatly appreciated.

I think I'd take the dark blue response. Is there a reason you took that measure at such a high target? I'd stick with 75dB, so that you are comparing equal levels.

I had to increase the volume because there was more ambient noise when I took the dark blue graph...neighbors mowing the lawn.

What worried me about the blue graph was the number of dips....it seemed like i had dips at all harmonics of some frequency. Would a BFD dsp1124p solve this problem? I really dont have any way to do room treatments.

I'd retake the measurement when there wasn't competition from a lawnmower........ the response looks suspect.....

Will redo the graph this weekend. Its getting colder here so no lawn mowers hopefully.
