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

I’m listening to Fritz Carrera 7 BE’s with a Pimaluna Evo300 amp and it’s a great match. Highly recommended for your situation. Can usually find these used for under $3k. 

Monitor Audio Silver 300 7G Loudspeakers. $2600/pr.They work incredibly well in smaller rooms. The dual rear ports allow fine tuning for your room. The rear driver mounting setup bolts also allows tuning the cabinet to your taste. But don’t take my word for it. Take theirs:

- The Absolute Sound Editors Choice 2025

- The Absolute Sound Editors Choice 2024

- The Absolute Sound Editors Choice 2022

- Audio Test Magazin and Like HiFi Editors Choice and Product of the Year 2024 award (In a 5.1.2 Dolby Atmos setup}

- Sound Stage Reviewers Choice 2022

- StereoNet Applause Award 2022

Stereophile also rated the Silver 500 7G (same speaker w/ 2X8" woofers and larger cabinet) as one of the very few Class A speakers under 10,000 per pair. They cost $3500.The reviewer thought that was per speaker, not per pair.

The S500 7Gs work better in larger rooms farther from the walls. The 300s which are intended for smaller rooms and positioning closer to the rear walls - a reality in your room. While not as efficient as some, in your room and your amp 100dB peaks are realistic. The tradeoff is they will deliver an honest 41Hz bass guitar low-E the others simply cannot. That’s Hoffman’s Iron Law - You can have low bass, high efficiency, or a reasonable cabinet size - pick any two. Everything else, tonal balance, soundstage and imaging, dynamics, PRAT, you name it, are all anyone could ask of a speaker in this range. FWIW, I also own KEF LS-50s and Magnepan .7s. My MA S300 7Gs would be the last to go.

Early 80’s in New Orleans, the audio dealer that recommended C-J MV75 amp & Pv2ar pre for my new-used ‘78 vintage Klipschorns stopped by to hear my system and asked if I wanted to hear a couple of bookshelf speakers he was fond of selling.

The Spendor speakers he placed on top of the Khorns were so comparatively small I was prepared to be underwhelmed.

Shockingly, the sound emanating from those “pipsqueak” speakers nearly duplicated the soundstage of the horns….falling short in the low end only (marginally). 
In short, if I ever shop for speakers again Spendors will be on my list.

Audio Note ANK works best in a room that size. I know, that’s my exact room size as well. They are made for it. Of course they play well with tubes. 

Unfortunately they are out of price range new. You can find them close to your budget occasionally.
