"Even Jim Smith (Get Better Sound) rarely mentions changing the sound coming out of the speakers, but focuses primarily on changing the room to fit the speakers. That thinking seems backwards to me, but I'm just a lowly mechanical engineer...or am I missing something important here?" Quote from t8kc-
Just to pick this thought up a bit, I think what happens quite often, and even I have been guilty of said thing, is that sometimes we try to "fix" what we think are sound issues with different gear. The thinking behind this is that it will somehow fix the problem, when in reality, the issue could very well be the room itself and poor acoustics-probably more times than not. While changing tone controls etc. in effect changing the sound coming out of the speakers, rarely will the changes given by ordinary tone controls really fix issues. It might make some things more pleasing to some degree, but room acoustics tend to go far deeper than what we can fix this way.
While I don't know if this is exactly what Jim's thinking is here, as I have not read any of his book, it makes sense to me. Get the room as acoustically "fixed" as possible, then work with the gear/speaker side of things. Of course this also brings up differing means of treating the room depending on the type of speaker to some degree-such as Magnepans, Omni's or front driven speakers. Even though the basics can apply to every one of these, each one also may have a slightly differing means of going the next step further.
The nice thing is that in my opinion, most Ohm speakers are a bit easier to work with room-wise. I always called them a more "friendly or real-world" speaker system. While certainly benefits can be had by taking the room acoustics and setup to the utmost degree, I find they just work fairly well with minimal fuss overall.
For what it is worth!
