Maggies, schmaggies! (LOL, but only partially not serious)
Look at the Maggie killer: Eminent Technology LFT-8C. Beats every Maggie up to and through the 3.7i - better, more articulate and deeper actual base. Coherence cross the bass to midrange transition. Far purer and lower distortion mids, and same for highs (until you get to the 3.7i with actual real ribbon tweeter). Also more dynamic, being push-pull instead of single-ended.
OP’s room is similar in size to mine, which is 25.5 x 15.5.
I agree with everyone else, stand-mounted would get sonically LOST in that room
In that $5K +/- range, you won’t do better than BMR Towers, ET LFT-8’s, or Ascend’s top offering WITH the Raal tweeter.
Really boils down to to “are you a planar guy, or not”? I’ve been a planar guy ever since moved on from Vandersteen’s to (at first) Maggies, and then (rapidly) to Apogee Duetta Signatures.
Disclosure: I have a listening salon where folks can listen to things like the ET’s as well as the full Schiit range. So, yeah, stake in the game (potentially).
