What is the best audiophile speaker for a tiny square room?

Beware of vendors who tell you that other people’s products don’t work. There is a huge conflict of interest there.

If heat is the big issue, are thermionic valves really the answer? Not all SS amps run hot. The Pass Labs ones do, but the newest ("cubed") Brystons run quite cool. Maybe you could audition a 14B3 or pair of 7B3s and see what you think.


If you do want to change speakers, the Janszens (I own a pair) are easy to place and easy to drive and will give you a good measure of electrostatic low distortion and transparency. They will not give you the rear wave of large panels and the sonic presentation may seem smaller than Magnepans or SoundLabs.

Someone already mentioned the Ls50 but in your size room rhe smaller LSx versions may do just as well. This and room treatment should give a precise enjoyable sound. 

I have them in my bedroom as a 3rd/4th system and they sound great once level up a bit. (not a whisper system)

I also think Kii Three or Boenicke W5 would work great.

I would research Ohm Speakers.  They are designed to go up against a wall and come in three different sizes.  They have been well reviewed.
