What kind of budget are you looking at? I own
SVS Ultra Books for my front 3 and they don't fall apart under pressure. Since I'm using subs low end is pretty much a non issue, but the Ultras do play flat down to 48-50hz with authority. I've never bottomed them out even at high spl, using them full range without the subs.
They're very good speakers and have no problem filling my large room with sound. I can hit almost concert levels at my seating position. I got all 3 of mine from
their outlet. 2 of them were $399 and the third one I picked up for $349. That's a steal for what they are. With a 45 day trial and free shipping both ways you can't lose.
