Paradigm: Monitor 7 v.3 Better Than 11se Mk. II

Ok, this might seem like a stupid question, but I need to ask:

Right now I'm using Paradigm 11se Mark II speakers as my main/only speakers. As far as I can tell, these were made from 1989-1992.

I have an opportunity to buy a pair of barely used Paradigm Monitor 7 v.3 speakers for $225 locally. It's hard to tell exactly what years they made this model, but they started making the Monitor 7's in 1998 and are still making them today. I think they're on version 5 now, so a good guess would be early 2000's.

Should I expect a marked/significant improvement if I go for this? I really enjoy the 11se Mark II's, but the one complaint I have about them is they're a tad weak in the bass, especially since I listen to a lot of rock music. Do you think the Monitor 7's will improve this?

Ok, in a way this is a no-lose situation, as if I buy these speakers, I can likely sell the other ones for at least $225 and lose no money, but before tying up my money for awhile that I have reserved for other components, I'd still like to get people's POV's here. Do you have any experience with these speakers? Is the fact that it's a Paradigm model 10 years down the line enough to warrant this purchase?

Your help would be gratefully appreciated.
