LSA110 Statement as possible replacment for Silverline SR17.5?

I was wondering whether the LSA's sub bass radiator might offer deeper, tighter bass. However, I read one review that mentioned the SBR might require more space between it and the back wall than other monitors and. I've only got 24" -- not sure this would be enough. 

Another speaker I'm wondering about in this regard is the Salk BMR. 

room dimensions?

17 X 18 living room  with a 17 X 10 dining room behind it, separated by a half-wall (5 feet high) and an adjoining entry on one side.

soix: Since I really like my Silverlines (although the system could do with more bass) I was thinking the Supremes would give me the same sound, only "better". Perhaps this is a naive assumption. When I asked Alan Yun about the differences, he replied that the main improvements are power handling and resolution. Because I tend to fall into the "musicality" camp as opposed to the "detail" camp and cannot actually demo the Supremes in my room, I'm a bit nervous about buying them, even at a discount. Perhaps this anxiety is entirely unfounded? I've haven't bought anything in the past 15 years I couldn't demo first, having learned the hard way, early on, that it doesn't matter how good gear sounds in a store.  

I only recently read about the LSA's, which come with a 30 day trial, and thought they might be provide more bass, due to the sub bass radiator. Supposedly, they are patterned on a 10K monitor, so I thought I might not be giving up anything. Again, perhaps this is naive.
