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


I currently have Soundlabs M545 electrostatic speakers in my 9 x 11ft room. They are great speakers particularly for this small room because they are more directional than box speakers and therefore decrease sidewall reflections. However, like other electrostatics, they are hard to drive and require big amps (>200W), which tend to generate a lot of heat. Class Ds don't go well with ES speakers. Are there great easy to drive speakers that would work well in this room without compromising SQ?

I was thinking if the room is really small open baffle may not work since you need to bring them away from the back wall. Take a look at the Larson speakers. The are very natural and they go right up against the wall. Some heritage klipsch speakers are also designed to go against the wall and are very efficient.
The Digital Amplifier Company 2Cherry or Meagaschino amplifiers would be a perfect match for your Sound Labs. Tommy does extensive listening and measuring with different types of speakers, one is a large Magnapan. I have had a number of his amps and Dac’s over the years and currently using a 2 Cherry on my Charney Audio Companion Horns. DAC offers a 30 day return policy.

If you are considering a different speaker for your room look into the Charney Audio Maestro Horn with the "Voxativ AC 2.6. They are designed for smaller rooms like yours and deliver on all counts.

Hope you find what your looking for.

For a small room and near field listening, nothing beats the Audio Physics Step. No longer available but worth seeking out.
