A friend of mine (well, his wife is friends with my wife) bought a Bose cube system some time ago because back in our day Bose had a reputation for making some kickin' speakers (that should let you know how old we are). Now Jeff liked to play the "I got" game-you know, "I got this for XXX dollars" (implying that, for that much money it must be the best). I showed up on his doorstep one day when he was trying to figure out what went where, and since he knew I was *into* stereos and HT he asked me to set it up.
I spent the afternoon screwing around with speaker placement, (and furniture location, to a small extent), and finally concluded that the cube system he bought was so-so...at least to my ear. I thought that the speakers were a bit bright on top, a little muddy on the bottom (with the sub; non-existent w/out it), and that the mid-range wasn't very clear either; once or twice I thought I heard the fragile little plastic speaker cases vibrate. Jeff popped in a few DVDs and CDs, and while I thought that the Bose were tolerable for small room HT and rather awful for music, Jeff just bumped up the volume a little higher and proclaimed them perfect...to each his own.
Now if I were going to buy $1300 worth of HTiaB, I know of two I've personnaly heard I thought were better-Denon has a jammin' little HTiaB setup, and the DefTec monitor 80 series w/sub were both much cleaner and, well, *balanced* sounding, you know? Boston Acoustics makes (made?) speakers that were comparable in price but not as bright as the DefTecs, and then there is Polk, Infinity, KEF...the list goes on and on. Wanna drop more cash? Try the higher end stuff from these same manufactures but add in the low end stuff from B&W, JMLabs, Tannoy, Spendor, Quad, Totem, Energy, etc.
From your post it seems you've got a pretty good-sized room you'll be working with (about 30 feet by 25 feet, right?), so if you are inclined to assemble your surround system yourself I probably would lean towards a larger, more efficient speaker in front for two reasons: 1, larger *usually* allows lower freqs (bigger cone+cabinet volume); and 2, speakers w/ less than 87 or 88db efficency will need a lot of power if you want to put out some volume. And get a decent sub, if only for movies.
Don't worry if this seems confusing-I rarely ever manage to make sense on the first try, and there are some really knowledgeable people here who also write better than myself-I'm sure they'll be along shortly to correct and clarify what I wrote. In the meantime, go listen to as many different systems as you can; take one or two CDs and a DVD you know well to use for references; if possible, try to listen in direct modes, or at least avoid using a DSP; and lastly, if it turns out you like the Bose system best, then buy it-you only need to please yourself.
