I am owner of the Fritz Carbon 7 SE MK2s. I have no doubt that they can be driven to loud levels with the OP's 20wpc amplifier in a room larger than 10x12'.
My only concern is that they would likely sound best at least 2' from the wall behind.
Seeking speakers under $3K for 10x12 ft room and driven by 20wpc tube amp
I currently have a pair of Apogee Acoustics Centaur Minors driven by a new Black Ice integrated tube amp. The small but dedicated listening room means I’m doing near-field listening with me and the speakers forming a 6’ triangle. As you might expect, these speakers have terrific midrange but at 85dB sensitivity they are a bit difficult to drive and feel limited in dynamics. The room is acoustically treated.
I almost exclusively listen to small combo acoustic jazz and vocals and I’m seeking recommendations for something easier to drive and more dynamic that provides a more “palpable presence” of the musicians when played at louder levels. Prefer small floorstanders for aesthetics but not essential and preferably a brand where I might have a chance to audition them (I’m in SoCal). Also open to used (e.g. something like Wilson Cubs). TIA!
p.s. thanks for the Sonus faber suggestion.
