KEEP the RS1b's - you can make them into world-beaters with some modifications, if you are up to it.
Here is a thread from AudioKarma where I ("Maxamillion" over there) go step by step through the modifications I did to my RSIIb's which have turned them into the best speakers I have ever heard. I'm sure you can get some ideas for your RS1B's from there.

In short, I built new outboard crossovers for them, upgraded the equalizer components, braced the cabinets, and MOST IMPORTANTLY installed the new EMIM diaphragms from Apogee. Those new diaphragms are head and shoulders better then the stock ones, here are links to the Apogee EMIM page, followed by reviews of the new EMIM diaphragms from folks who have installed them:

You are welcome to stop by my house and hear the RSIIb's in their modded state if you are near New Jersey. Just send me an email.
