Smaller speakers that can handle power can throw some insane stage properties. Even in difficult spaces - to a degree. I’m floored by how my Spendor 4/5 Classics can maintain composure, naturalness, pump dynamics and throw deep and wide with care in placement (got them used for $1300). But having a good amp and pre at about the same price really made this happen too. What kind of amplification have you got going?
Tech is getting crazy good with powerful class D and chip amps if you wanted to get something affordable that can get you in the ballpark.
No need to go crazy in your room, but you will at least need to get some diffusion/absorbtion on your walls with symmetrical placements. Many diagrams out there to get you started. Not the only solution, but GIK can help with suggestions. Just send them pics and they’ll give you some free advice.
A totally different direction would be to save up and get a pair of active speakers with room correction capabilities via house software. Buchardt Audio has a couple of amazing setups with their own dedicated stands. A local dealer has a pair of small Cabasse Rialto speakers that would just blow your mind. Crazy good sound stage, and surprisingly refined tonality. Has its own dacs, streaming capabilities. Something like 1,000 watts total amplification separates between a concentric tweeter/midbass, and a powerful rear-firing sub. It has built in mics to aid with a cloud based room correction to boot.
But they’re $3.9k.
Any way you slice it, placement and at least minor treatment within the room is pretty essential.
