Experience: none meaningful. I'm the only person I know or associate with that even seems to believe there's a meaningful difference between $50 and $1000 speakers. Until the last few months I've been too poor to move upward from typical consumer audio so didn't tempt myself with the awareness of what I was missing. I'm in a city that's just a bit too small to have much in the way of higher-end dealers, although there are a couple I'll check out now. And I feel bad deep down inside going to them and not buying anything. I'll get over it.
What I want: I can't say I have a target for bass frequency, although somewhere below 50 hz might be nice. I'm just trying to balance out looks, performance, and price and since I have no idea what's out there any suggestion is as good as the next. I'll admit that if there was the perfect speaker performance- and price-wise, but it was an ugly black box, I'd more than likely pass over it. Front ports are a plus, given the placement constraints. And I'll add a sub at some point. Actually I have one now but it's crap and if the speakers I get are good enough I'll make it go away sooner.
So yeah, I'm not making it easy on myself or everyone else, but at least you're all increasing my awareness of options. Which is exactly what I needed. Tips like suggesting the Axioms are better seen from a distance are wonderful, since I really have no way of knowing short of ordering them for a trial. I'll keep looking.
Here are my general household goals though. Home theater system will be mainly that. I'm planning on upgrading my current 105 w/channel Yamaha to the RV-2500, Polk RTi series speakers all around (10s front, pair of 4s center, 8s rear), plus existing Velodyne DPS-12. Availability and mid-range performance are all I need there. It will be good enough, and if I want to crank some music I'll have a place for it.
Most of the time though will be spent on my computer system, the one under consideration here. I've already got the HK 3480 receiver and crappy JBL POS-1998 sub with O.L.D. technology, Sennheiser 600s for late nights, and just need some proper speakers. Pseudo-audiophile quality, something that the untrained ear couldn't really find flaws in. And good looks too.
Sorry. I've got no clue. But I'm trying!
