Recommendations for speakers in a much smaller listening room.

Another vote for the Harbeth P3esr. Had the M30.2 and loved it but they are around 5k$. The Harbeth P3esr is the best value for the price IMHO . And you need to leave room for good stands. The Ton Trager are second to none to match Harbeth if you can find them second hand. Another option to explore is the Dynaudio special 40. An excellent well balanced speaker. Good luck and keep us posted.

Another thought on smaller room speakers. Let’s set the high bar. Cost no object smaller room speakers. Id offer these two: The Steheim Two.Five at $23,500 per pair and the Josep Audio Perspective 2 Graphene at $16,999 per pair.  Oth are specifi6designed for smaller rooms, both are compact floor standers whose foot print is no bigger than a mini-monitor on a stand, and most interesting, both are 2.5 way designs - 2 smaller woofers run in parallel, rolling off the lower woofer early, at around the baffle step frequency. The smaller drivers also can be crossed over higher before off -axis beaming is an issue, and tweeters don't have to cross over so low as to compromise their power handling.l The advantages are extended bass and greater woofer area (for bass ’slam’) in a small cabinet, without compromising the midrange coherency, a simpler overall design and simpler crossover compared to a 3-way, which means less crossover insertion loss, fewer phase anomalies and greater ’livliness’ than can be achieved in a compact 3-way. 

Both the example speakers given are way above your (and most peoples!) price range, but using those design characteristics might give you some good clues of what to be looking for. For any given system, the first 90% of possible performance is achievable for 10% of the cost of the last 10% of performance. 

Hello @backwash 

your room is something close to mine (13x23). If you are willing to listen near Field, then i highly recommend the Falcon Gold Badge. LS3/5a and supplement it with sub. This is my reference setup, powered by Pass Labs Xa-25 OR my Audio Note Clone 845 Tube Power amps. I just need to say that this speakers "disappear" into space and music just flows from the front of the room. This speakers makes the rear wall disappear with the correct recordings. Its only disadvantage is that it does NOT play LOUD.  the loudest i played it was about 90 to 95 DB. This speakers generate the correct tone and timbre.  I can go one and on, but seek out Herb Reichert (Stereophile) for his comments

I suggest that you give it a try

@backwash .... I’ll try some lane-splitting from by mcycle daze (legal in CA, not so much elsewhere) and advise within your budget.... ;)

Try the existing Tyler’s in the new space and let your ears get used to it.
Didn’t notice a mention of which wall is ’stage’ v behind, so start with the basic layouts.  No mention of the floor type or surface; if ’vanilla’ (hard, no carpet) get some sliders to nudge the towers about.
Since you’ve existing traps and such, give ’em a go and mess about with the spl meter and ears.  The price so far is just labor and listening....👍

@mapman suggested DSP, of which I’ve applied in ghastly spaces to decent results with the less than stellar sort of gear.  You’ve a leg up if you’ve a ’puter in the closet that can be uploaded with some of the freeware DSP or the Parts Express ware and mic.  A calibrated mic with a tripod beats having the spouse tolerating standing about getting tortured  with test tones... ;)
The above will help in dialing your subs, which a pair could easily load the room beyond rationality.....
Buy a nice carpet and a backing for it.  Assuming you’ve already have some suitable seating; perhaps the carpet as well.

If up for surround, match the tall Tylers with a smaller pair later when the muse moves you there....

Any new space should be an adventure and an opportunity to dig out the ’faves’ for a revisit to what sounded  great before.  Y’all are going to stay put for awhile, so rushing into the process can dissolve into a unnecessary PIA.

Enjoy yourselves....pour some wine or whatever floats the boat for the 2 of you.
It’s supposed to be fun, so have some. 👍😎 

Happy trials, J
( PS: I’ve got similar in my future and that’s my approach in the nutshell... ;) )

Here are some other options to consider, I would recommend at least a small subwoofer with any of them.

Harbeth Compact 7ES-3

KEF Reference 1 (you should be able to find non-meta used within your budget)

PS Audio Aspen

I have the Compact 7s and P3ESR.  The P3ESR are incredible, but they have limits.  If you don't ever listen loud, that's a great option.  The Compact 7s are great and can take some power and keep their composure.
