Best speakers for a small room

The Charney Audio Maestro is designed for smallish rooms. An 8” full range single driver designed from the tractrix theory. Can be placed against or near the front wall and corners. Depending on driver and finish they run from $2800-$6500.

Any of the Sonus Faber Guarneri models will work well.

Vandersteen VLR CT is perfect for a small room. They are designed to be placed close to wall and will not eat up much space. 

Several great options... these are some of the better ones:

1. Harbeth 3PSR

2. Triangle Comete EZ

3. Wave Touch Audio Antero

All of these sound superb.

I have the Harbeth 30.1’s, which I got because they have such captivating sound with the right amplifier. But, they’re more expensive. And require a properly matched amplifier (SS amp like Hegel).

I do not have the Triangle Comete EZ - but, they get some very good reviews by a lot of reviewers, who have reviewed them highly with some good tube amps.

I also have the Wavetouch Audio Antero’s - which also sound amazing - perhaps as good as these others, have a room filling sound, with great transparency and resolution. These are efficient enough to be driven by a good tube integrated amp - such as a Line Magnetic.

Hard to choose one set over the others... Though, the Harbeths have a big brand name, and are easy to resell... and... tend to sound a lot like the venerable Quad ESL-57’s with the right amp. But, they are much more expensive.

So... you have quite a choice...

First priority is room correction.  Second is actively driven. Then look for sonically neutral / flat speakers.  I use Dirac, Linn to achieve all three, Kii has some interesting looking kit…
