One has to be in the room to answer those types of questions as not being omniscient, it would be unreasonable for one to comment in the specific as opposed to the general on a room they haven't seen. I'm not playing word games. I haven't seen the room, so how can I comment other than in general terms?
I already said opening walls can make a difference . (In my case, they were negative differences).
Actually, you mentioned opening doors as opposed to the actual wall. If the reflective surface is not the cause of the standing wave, then opening door or wall won't make a difference but it will reduce the reinforcement of a sealed room; negative impact. And if the reflective surface has been removed that reinforces, then a null can be created by it's removal; negative impact. The point, yes, I understand there are complex interactions within a sealed environment.
All who live in Silicon Valley know about the interaction of the Mt View based Shoreline Amphitheater and how it's outdoor acoustics affect many households, miles away as the concert sound waves choose to gather in their bedroom using nighttime air vs warmer daytime air. This is an example of complex interactions. The same can be said for internal acoustics of homes in the path of the local airport runway. Even takeoffs can be an indoor problem for homes that are well over ten miles away; ya gotta love the bass. Unfortunately, due to the higher frequency of thunder, one has to be outside to fully appreciate the sonic range of thunder as it cascades across the sky versus what one hears inside; complex interaction. Currently, I'm in the home office on the other end of the home. I know the wife is awake when I here the whistle of the pipes; complex interactions. On school days, we have trouble having conversations on our front porch in the morning due to reinforcement issues of passing vehicles. Of course school buses are the worse. Again complex interactions and yes, simply removing the walls of the front porch will solve the problem as stepping down to the front yard, closer to the road, the problem goes away. Running calibration sweeps inside our home has it's foils. Although having double paned windows coupled with 2x6 construction and insulation, passing vehicles play havoc with calibrations sweeps due to reinforcement issues and there's nothing that can be done short of doing sweeps in the middle of the night when no traffic; again, complex interaction. The point of the above, we're surrounded by complex sonic interactions that don't just end at the nose of Home Theater.
And why would I want these questions on a PM? I'm sure there are many interested in what your specific recommendations are and why.
And I'm sure many here just want to argue for the sake of arguing and by taking the conversation to PM, the arguments end. I answered a question. Enough has been said. If one wishes to continue with off topic conversation, please PM me. Otherwise, how do you like your SubMersive subs and if you changed the phase so not in sync with each other, how did changing the phase improve or deteriorate the overall bass sound quality in your Home Theater?
(The world as we know it is not going end on the 21st.)
