Speakers least affected by room acoustics

I would suggest something a little different: Larsen speakers are designed to work with virtually any room and sound great.  Larsens are an updated version of the Stig Carlsson designs.  These come in three models, at different price points starting at under $2K.

They are designed to be placed on a long wall in your room, right up against the wall, compared to OB and/or dipoles that require placement several feet out into your room.  I used to sell these (no affiliation now) and I never found a room where the Larsens didn't work.

I sold a pair of Larsen 8s to a gent who had the worst room I ever experienced: 35' wide, 12' deep, 12' high, the front wall was rock and the rear wall (behind the seating position) was all glass.  Think of an enclosed porch.  On top of that, the preferred seating position was offset 2/3 to the right side of the room.  Long story short, after some careful positioning the Larsens sounded great, even in this room.
 

I have speakers in various rooms, including a similar room to yours with similar high ceiling and acoustic challenges and no ability to treat (WAF).

I’d propose fighting the acoustics in a room like that, especially if not able to do extensive treatments, is an exercise in futility.   That has been my experience in my similar room especially in comparison to other more amenable rooms in my home.

In cases like, that, I would propose not fighting the acoustics rather just let the music flow with more omnidirectional speakers that will fill the room with sound rather than attempt and fail at projecting it solely towards you. This will at least give the impression of what a live performance would sound like in that room rather than some artificially echoey mess.

I use OHM Walsh speakers in my room like that. I’ve also tried various more conventional monitor speakers in there as well largely to no great avail but these particular omnis work pretty well.

You may have the best success using digital room correction. Lyngdorf TDIA 2170 looks really nice. I’m thinking about pulling the trigger on one.  

mofojo, good point!

If you are determined to fight the room acoustics, digital room correction is the ticket!

Or just go omni for a "playing live in your room" kinda sound, learn to love your room (its your own unique concert venue after all), and be done with it.   

I own the Lyngdorf 2170 and have been a vocal advocate of this gem. Yes it is the ideal system for your situation. It is amazing amp, preamp, dac, and SOTA room correction system all in one attractive case. It will assure your speakers sound as intended in your room.

I have owned separates of both SS and tube design that cost $20,000 or so combined and the 2170 is better. The room correction is part of the reason. Give it a good power cord, conditioner, leave it on and you will be amazed at the beautiful music you hear.

The key to getting the most out of it is using the internal dac. The synergy and simplicity of the one unit will have you selling that expensive dac you may have. Sell those other power cords and ICs as they are also no longer needed. USB input sounds the best and can do DSD. It only pulls some 20-30 watts while in use and never gets hot. It runs cool. This piece is a no fuss centerpiece of an audio system that is not fussy to use or to make sound right. Set it and forget it while you enjoy music with beautiful tonality and richness.

It flies under the radar here in the states, but it truly is a rare find. The sound quality difference pre and post room correction will be shocking in your room.
