my question was whether or not a subwoofer between speakers would have a negative effect on imaging & sound staging; if I am reading your answer correctly, you are saying it is room dependent.
I have some comments on the video, but I spent another tough day in the garage & I am awfully tired right now. Briefly I would say that while it was interesting, I think that home theater systems & music only systems have different desired effects from their subs. However, with that typed, I realize that the principles (localization, standing waves, etc.) are probably the same. I found the discussion of the subject to be complex, reminding me that I am not doing a good job of integrating into the 21st century. (Good thing I probably won’t have to deal with it a whole lot longer.)
One thing I was able to grasp a rudimentary understanding of is WHY two subs are important. And NOT for the reasons I previously would have thought--music or HT. A couple of other things I learned, my near field listening room is not sub suitable, and, my sub is probably obsolete. (It is a M&K I bought in ’94 after I was introduced to the wonders of Dolby Pro Logic. It was actually my first venture into ’better’ audio equipment.) I just did a 180 in my near field listening room, and although I like some aspects of the rearrangement better than before, I lost a lot of what I had been getting out of my sub. There are three or four other things I want to try with the speakers & the sub, but I am starting to think I may wind up removing it from the system.
My near field listening room has a couple advantages from the previous living room location . . .I enjoy the isolation from distractions, and after my beloved Rat Terrier died last year I over compensated for the loss by adopting THREE dogs, and two of them were Staffordshire Terrier (aka Pit Bull) puppies, and although at a year old they are turning out to strike me as rather lovable, I could throw them further than I trust them (& I couldn’t throw either one of those Tasmanian Devils very far at all), so the near field room it is. Depending upon who outlives who, I may or may not ever be back in the living room, which was far from an ideal room, but even with the distractions and lack of autonomy, I do find that I miss the flexibility.
Oh well, Ramble On. Thank you for posting that video; I enjoyed it, and I may refer back to it.
