Thanks - I do not have a high end mic and measurement tools (outside of the Audyssey MultEQ app, if that is acceptable), but may have access through a friend who is a sound tech. I will check in and see if I can post that in the next week or so.
I'm an accountant in my day job, and I know enough knowledge in the realm of frequencies to be dangerous, but I'll try to describe the sound I am hearing and trying to improve:
1) As mentioned above, in home theater usage I find that dialogue can often be muddy or muffled, or gets overpowered by the left/right and surround speakers. It's not terrible, but it is often enough that it is distracting.
2) Music seems "heavy" on the lower frequencies and flat. The best I can describe this is that when I first began this quest for sound (mid-90s) I inherited some used Klipsch (Cornwall?) speakers that I connected to an even older Yamaha amp and receiver I bought used. To my untrained ear that sounded "clean" and I swear the full spectrum of instruments filled the room much more distinctly when listening to music like Pink Floyd, Steely Dan, or various Celtic music I listen to. I know technically the B&W's have a a much wider frequency band than the old Klipsch, and my current setup powers them fine, so this is totally subjective and is likely biased. It just sounds now like the instruments are not as distinct, and while loudness is not an issue, I cannot hear the higher ranges as cleanly as I did before and the music tilts toward bass and low-midrange, and the upper frequencies seem really subdued.
That's the best I can describe it - writing this I wonder if my hearing has changed over 25 years and it is me, and not the speakers, and I also see the benefit of doing a more rigorous technical analysis.
I will come back in a week or two once I get the spectrum frequency analysis of the room, and also post pictures of the room.
Thanks for the help!
