What are your thoughts on room eq? I've got Audyssey XT32, and I find very little difference with it on or off. With it on, vocals seems a little more centered than without, and the bass is noticeably more defined and smooth. Other than a preferred improvement in the bass tho, the overall tone doesn't change. I believe my speakers are fairly neutral to begin with tho.
Folks who sell room treatments talk as though good sound is impossible without it, sometimes a lot of it. If you start with an empty room, as in a dedicated home theater, there is no doubt that treatment is necessary to bring the room acoustics to a desirable level. If the room is carpeted, furnished with chairs, sofas, paraphernalia of life, including some drapes, nothing further may be necessary. So, it depends . . . I discuss some of this in the companion website to my book, which is open access: www.routledge.com/cw/toole
My book is full of commentary on room EQ, much of it negative, except for the bass, where it I almost essential. Full bandwidth EQ, as frequently practised, is capable of degrading the sound from well designed loudspeakers. When I was teaching acoustics to CEDIA classes of installers I would ask the question about room acoustics. In those days, up to 2 years ago, the answer was predominantly "off". I still claim that EQ is useful at low frequencies, especially when combined with the proper use of multiple subs - no bass traps necessary, although they do no harm, except to the visual environment. See Chapter 8 in my book for full details. This paper has most of the "technical" arguments: Toole, F. E. (2015). “The Measurement and Calibration of Sound Reproducing Systems”, J. Audio Eng. Soc., vol. 63, pp.512-541. This is an open-access paper available to non-members at www.aes.org
