I hear you, Jerry. I agree with everything you've said, and I certainly didn't mean to come off like I was ignoring anyone's advice.
For example, when you placed the treatments on the side walls, did you determine their exact placement using a mirror?
Yes, I did use a mirror. I did hit two of the sidewall first reflection points with the panels, but due to the window on one side and the edge of the wall on the other, perhaps I didn't hit them as squarely as might be desirable.
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.
I understand this and I definitely intend to measure... This actually brings up something else I was wondering about. I was initially thinking that people would mention the placement of the two windows as being a major problem in my room (one is directly on a sidewall first reflection point, and the other is directly behind my head). So far no one has mentioned the windows. Thinking about this more, I wonder if the windows, especially covered by heavy drapes, are better than drywall. The data I've seen suggests that below 1 kHz windows absorb more than drywall, and then perhaps the drapes on top do a better job on the frequencies above that. Does this sound about right?
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.
Makes perfect sense. I will try this.
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).
Completely agree with this. As I wrote above, I'm definitely leaning towards eventually going with a second sub. Although I'd like XT32, spending $500+ on another receiver isn't something I'm considering.
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.
That is good to know you think a DSP might be useful. This may actually be the next place I put money. One thing about this, I know I asked this before, but just be clear, you don't see any complications on running the MiniDSP on the bass and then Audyssey on top of it? I seem to recall reading somewhere that this was not a good idea, but I suppose I can't think of any reason why it wouldn't be.
The only reason I brought up making the other bass traps was because I already have 4 sheets of Owens Corning 703 from a six pack I bought. I liked making the clouds, so I figure it couldn't hurt to put some panels in back or somewhere else that would hit a reflection point and perhaps make a small difference in the bass. I do understand that measuring everything carefully is sage advice.
Thank you again, Jerry. Both your advice here and your guide have been and continue to be very helpful to me.
