A lot of people are recommending the HSU HB-1s and matching center, but how many of you have actually heard these speakers? I ordered a pair of HB-1s and matching HC-1 center with a VTF2 MK4 sub. While the sub sounded great, I wasn't that impressed by the speakers. their greatest strength was going down low, up to 60 hz usable output that crossed over well with the sub, but as far as highs go, they were decidedly flat and almost neutered, to a point where it made all my music sound boring and flat. My Polks did a better jobs with handling the highs and I was really disappointed by the flat sound of the HSUs. Vocals did sound uniquely clean and some music sprang to life, but the HSUs just sounded kind of goofy.
With movies though, its a different story, they seem to handle dynamics pretty well and would probably satisfy most discerning listeners, they have a movie tone vibe, though the neutered highs do take away from the impact. My problem with these speakers is that they just don't seem to have much personality, it seems like they are more concerned with accuracy than with having fun like the Polks. There goes the colored vs accurate sound argument for speakers again, something you will have to decide about. The other thing that bothered me about the HSU speakers was that it took a lot to drive them, I had to crank my AVR to really get them loud, so they are not as efficient as they claim to be.
My suggestion, get a great sub, HSU or SVS, a decent receiver, then check out the Polk Monitor series of speakers on newegg. You'll get these crazy deals every once in awhile where you can get Monitor 70 floorstanders for 199 or less each. Get a pair of those plus a CS2 center and some surrounds and you'll have a budget system that has a lively fun sound and will crank loud.
Bottom line, stick with HSU for subs(thats what they do best), for speakers, look elsewhere.
