Bass driven floorstanders?

Perhaps a speaker with built in powered 12" drivers . 

Take a look at the Golden Ear Triton series.  Good bang for the buck and the model 3 (at the top end of your price range) has a built-in subwoofer.

chrisr, I have something for you to consider. Personally I beleive there is no way you're going to beat (price and quality aka value wise) this. And to maplegrovemusic point, they are powered with a 200 watt amp. They are rated to go to 32Hz. I have one used and one BRAND NEW (as in unopened manufacturers carton) pair of JBL S412P speakers. I'm selling them for $400 used, $700 new, $1000 both pairs. And to djohnson54 point, he/she is correct. I have a pair of T1s. The issue there is simply a matter of price. For what I have at the price I'm selling them for they are a better value than the T3s. You can contact me off board at [email protected] if interested. Thanks. Hal

thanks all for suggestions.. I have been considering the triton line; I know they have been received very well by the press, but a dealer carrying the full line and also selling mostly magnepan and b&ws, pretty much told me that they were not so impressed.  The store was busy that day so I could not sit for a demo.  I looked at the JBLs, but if I bring them home, my wife won't talk to me for a very long time....  I have tried to stay away from subs, because I read you really need two to obtain even bass throughout a room, and I am not sure they would blend well with my rega rs5 (thinking of velodyne impact 10, or rel or sunfire around $400).  My marantz integrated has no bass management capabilities, just preamp stereo output, and a second set of speaker outputs.
The thing about the regas is that midrange/trebles are the best I have ever had; they are just the last word when it comes to bass below 60/50hz.   

chrisr, please don’t take this the wrong way, but given your response I recommend (a) look for another audio dealer because if they poo poo the Triton’s, well, you get the point and (b) not sure if it’s because your wife doesn’t understand audio or doesn’t appreciate the JBL S412Ps size/look, but I suspect the former.
