The pictures were taken before I put up 2' x 3' 4" absorption panels on either side of the couch as well as the clouds. I also put heavier polyester blackout curtains up. Come to think of it, I should measure the ETC with the curtains open and closed to see if this really made any difference. My ears tell me a little.
I will try moving the couch up, but it would be a awkward to do this more than a foot. I know it is not considered great to have the couch so close to the wall. I may actually consider putting a panel behind the curtains in font of the window. I will measure this. Assuming the ETC is what to look at here? My main thought though is still to build two 2' x 4' 4" absorption panels on either side of the back wall. I will try angling them out a bit to create the air pocket back there. Or I also am considering framing them with a 6" width wood so a air pocket will be created that way. Not sure if that's enough space to do much good.
The way I'm thinking now, I will most likely look at another PB-1000 sub in the next few months. Seems most people here think this will make the most difference, which makes sense to me. My only hesitation is that the corner to the right seems to be such a crappy place to put a sub that I do wonder if this could be counterproductive. Still, my thinking is that this would make more of a difference to SQ than moving to XT32. (Of course I'm sure some people might look at that picture and think I'm out of my mind to consider a second sub with a TV that old, but hey, I'm more of a music guy than movie. A new TV will come too.)
This week I will definitely try out the blocking technique when I spare moment. Thanks for that, Jerry. And thank you to everyone who has helped me here.
I think you need to pause and think about all the suggestions you have received, and especially not make any big purchases or put up any new treatments without a specific game plan.
For example, when you placed the treatments on the side walls, did you determine their exact placement using a mirror?
Next, only place a treatment on the back wall if it provides a measurable difference in the reflections. With that window directly behind you, you may not have any reflections to correct.
Third, with respect to moving the couch forward, we are not asking you to commit to anything permanent. We are asking you to simply take several measurement with the mic placed in front of the MLP, more towards the front of the room, without moving the couch. If those measurements show a significant reduction in the 50Hz issue, then you can decide if the improvement warrants moving the couch.
Fourth, you have heard from several people now that an additional sub (placed properly) is likely to produce the most improvement. Consider this purchase before upgrading your AVR to XT32. Both are significant expenses, and you want the most bang for the buck (if improved bass is your objective).
And finally, if you decide on getting an inexpensive DSB unit, I strongly recommend the MiniDSP, which is less than $150, simply because there is a large community here on AVS that can help you configure it properly.
