Speakers for weird sized room.....

What equipment do you have now? What tastes in music and sound preferences? Head banging? Concertos?

Sonus Faber Olympica 3 used or new Nova Olympica 3. Outstanding for natural / musical sound with good dynamics and natural detail.

B&W for rock. DynAudio for more detailed mixed. Wilson hyper detailed and holographic.

Currently rocking with a Pass X1 pre, and Pass x250.5 amp,  Antipodes S30 streamer, and a Denafrips Venus 2 dac.  I listen to lots of live music.  Alice in Chains, Chris Cornell, Pearl Jam.  Stevie Ray Vaughan.    I was eyeing a pair of Wilsons.  The sophia 3, but not sure if my room is too narrow.

Long wall or short wall?

If it's the short wall, then dipoles come to mind.  Dipoles can be placed right smack up against the sidewalls because they naturally have a nulls to their sides, but they do like to have a fair amount of distance behind them, at least 3 feet and preferably 5 feet or even a bit more.  This distance from the wall behind them imposes a time delay on the arrival of the backwave energy, and ime this is highly desirable.

Your speakers are well regarded.  What specific improvements would you be looking for?  That’d be the key info here for making good recommendations here.

Short wall setup? Try magnepans or other speakers with narrow dispersion. Magnepans cancel a good bit of the lateral dispersion and work well in narrow rooms.
