A "small" room has problems with "larger" speakers for a variety of reasons. Not just room gain causing boomy bass. You may be unable to place the speakers far enough from the walls, depending on their port configuration (which might be a contributor to boomy bass) or off-axis response. You may be sitting too close to the speaker to allow for the multiple drivers to converge correctly. So speaker characteristics have an impact. It also depends a bit on your room treatments. Treatments can effectively create a virtual larger room, since sound is prevented from bouncing around.

Lack of "detail" in your existing speakers may be due to bad room acoustics, resulting from the room itself, speaker placement, and listening position. Or just the speaker.

Lack of bass is likely better solved with a subwoofer than with main speakers that run lower. You'll have a lot more flexibility in placement with a subwoofer and also get a lot more bass for your dollar than just speakers. Plus, if you try to run "large" speakers as large, you're probably making them reproduce the non-bass frequencies more poorly.
