Bill's got an excellent point. Room acoustics are the 2nd most important factor in a system, just behind speakers IMO...The best part about room treatments is that you don't necessarily HAVE to spend much, if any money at all to address most of the problems above the lower bass frequencies.

While frequencies above 500Hz can usually be compensated for with plants, wall hangings, rearranging furniture slightly, and are really subject only to reflections, the lower frequencies, especially below 100Hz are highly subject to your room acoustics.

Granted, in any given room, it holds that a better speaker will still sound better than an inferior design, it will still very much suffer from whatever drawbacks your room has.

I can't imagine why anyone would spend a pile of money on cables, but leave their room less than optimized.

Perhaps you could draw us, or tell us about your room, and what exactly makes it "very bad for acoustics"...I'd almost recommend in a new thread so as to attract others to assist you...lots of knowledgeable people here at ar.com.
