I would like to apologize in advance for my newbie-ishness. I’m sure the most annoying and common post is “What is the best [component type] for [amount of money]??!!” I’m new to these forums and to home theater in general, but I’d like to think that I did at least some of my homework before asking my question. Anyway, here’s my situation: I’m a college student trying to get the best setup I can with less-than-optimal circumstances. Firstly, the room I’m looking to put my theater in is not rectangular (see diagram) by any means, and I'm not expecting a good and even sound image as a result. Further, I can’t really do any hardcore modifications because I’m renting this house and I'm not the only one living here. Lastly, and regrettably most importantly, I can’t spend TOO much on the system as I am making only $500 a week, and while my living expenses are covered for the time being (the whole living-with-parents-for-the-summer-because-you’re-poor thing sucks) I need to be saving for the coming school year as well. I currently own an Onkyo HT-S650 HTIB that I can cannibalize for components if need be, but I’m really looking to move up. It was a good system for $350, and it opened my eyes to home theater possibilities, but (un-?)fortunately I’m not tone deaf and can easily hear its limitations. My question is, what kind / range of products should I be looking at? A lot of the better systems have floor-standing front units with integrated woofers, but would their better quality be wasted on a far-from-optimal room? Should I even be concerned about the room shape/dimensions with the “budget” products that I am forced to limit myself to? I like my music and sound to be slightly warmer, more open sounding, and slightly more bass-heavy (but not to the point of boominess) than average. What kind/brand/model/quantity of speakers should I be looking at? I’ve heard good things about NHT, Ascend Acoustic, and Mirage, but nothing other than a few people think that they are good, more often than not neglecting to justify their statements. Would a 7.1 system help offset bad room acoustics, or would it be a wasted gesture? Also, if you could please throw in your two cents about a receiver to drive said system, I would greatly appreciate it. Of course I’d greatly appreciate any and all recommendations or advice.
