#146 ATC SCM19: $3750 per pair The Music Room eBay

Pros: Harmonic distortion at 96dB SPL/1m stays generally low across the range aside from the spike tied to the 700-800Hz resonance. Sealed (unported) cabinet avoids port noise and resonance, and the extremely dense, heavy-duty enclosure (17.8kg/39lb each) reflects ATC’s pro-audio build standards. Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 85dB.

Cons: Some stored energy resonance around 500-700Hz, 4dB bump around 700Hz. Not recommended for the price. CEA2034 spinorama and predicted in-room response both show a very uneven overall balance (a broad accentuation from midrange to treble paired with too little bass) along with directivity error. At 96dB SPL/1m, harmonic distortion tied to the 500-700Hz resonance rises to a level the reviewer says “should not be there.”

How it compares: Just above it: BIC America DV62si - $3585 cheaper. Just below it: Diapason Emera - $2700 cheaper.
