Overall, if you know your likely to be in smallish rooms in general, that are pretty rectangular and/or sealed off acoustically from the likes of hallway's, oppenings, other room connnections, etc, you should probably consider a sealed box speaker (as opposed to base reflex ported) with less bass extension! The smaller room is going to give you a bit of bass boost overall anyway, as opposed to likely possitioning in a larger room. Plus, what I've noticed from installing systems in small rooms over the years, is that it's much harder to get the speakers that play lower(usually ported) to have reasonably flat frequency response from any practical seating/speaker placement possition! The bass modes are just too steep and packed up in those rooms to get natural (non boomy/peaky/dippy) sound in small rooms usually(occasional exceptions from room to room of course).
Overall, you'll still have to play around with placement of things, and use careful consideration, if you want anything resembling good sound(especially in small rooms..especially).
May I consider something like, yes, the Spenders, or even better, the Merlin TSM-M's!!! AT around $2500 retail, they're impossible to beat! They're a sealed enclosure, and play down to about 50Hz +/-3 annechoically. In a small room, they do about 40hz realistically!(plenty low trust me) And you can augment with sub if you ever needed to.
They truely are world class, approaching (if not there) Solid Class A performance, and are an easy 87db to drive.(I think 8 ohms).
If you noticed, a lot of the high end rooms at CES show were using Merlins(TSM'm's or VSM'M's for their demo's!!!...and it's been this way for several years now!)
Anyway, it's a thought.
I used to use some very very very good Sonus Faber Electa Amator's and Minima Amator's($5k and $3k respectively), and these Merlins are better!!...and much better for small room acoustics in general, that's for darn sure.
Also, the Merlins can do tube gear or Solid state...My Electa's and Minima's only did SS well.
Good luck
