Seeking speakers under $3K for 10x12 ft room and driven by 20wpc tube amp

I am listening to a pair of refurbished Acoustic Research AR-2ax in my office, a similarly sized room to yours, essentially 6’ triangle. You could call them large bookcase, or compact 3 way.

They have level controls for both the tweeters and mids to balance their output in any space. I drive mine with a Luxman 10wpc tube amp. The 10" woofer produces full range without over-powering you when close. My prior Wharfedale 225’s 6.5" woofers needed a sub to avoid sounding small.

They sound so good, I restored a 2nd pair for my Garage/Shop system. I bought new level controls and new tweeters for that pair, and new grille cloth, everything is available for these.

A restored pair of AR-2ax, I would get the stands he shows them on also

I second the Reference 3A de Capos. i use mine with a 4 watt tube amp and the room is 12 x 22 and plenty loud and with great full sound even low volume.

I've hear soem Omegas and that is another great choice

Look at used Klipsch Forte IIIs, should fit your price range.  I also have a 6-7 foot listening triangle and a 20 wpc integrated tube amp w 300b driving 845 tubes. I usually listen 55-60 dB levels, not too loud but loud enough to feel bass punch and textures of detail. I’ve integrated a 12 inch Klipsch subwoofer at a level where you can hear/feel the bass, but can’t “see” the subwoofer. 
 

System synergy important, as are room acoustics and speaker placement along with good, but not necessarily expensive interconnects and cables. When the lights are down low, and the tubes aglow, the speakers disappear and you’d swear Grace Mahya is in the room with you. 

You are overthinking this with this, size room 20 watts will work with nearly any loudspeaker.

Even with a low efficiency monitor 20 watts will get you plenty loud enough

Look at a pair of Elac carinas 85db sensitivity will be loud at 85db the roon is very small and 85db is plenty loud for such a small room.

so you can look at nearly any loudspeaker.

I would be more concerned, with impedance and current deliver, however most 2 way compact, and affordable, monitors will be easy to drive.

I would strongly recommend one of the smaller Revel PerformaBE speakers. The performance-to-dollar value of the Revel PerformaBe speakers is off-the-charts!!! Beryllium tweeters, super tight, deep bass, 90 db, and beautifully constructed. The combination of the smooth Beryllium tweeters and your tubes, would be a match made in heaven. For your room, I would definitely go with one of Revel’s small PerformaBE floor standers. You’ll most definitely get your money’s worth with Revel speakers .
