#66 ELAC BS U5: $856 per pair Discontinued eBay
Pros: This slim three-way coaxial design (an Andrew Jones creation) shows a fairly even on-axis response up to 3kHz, with off-axis behavior notably smoother than the on-axis curve. Predicted in-room response looks like it should give good tonality. Vertical directivity is better than average, a benefit of the coaxial layout. Measured bass extension of 63Hz (-3dB), with a measured sensitivity of 83dB.
Cons: Distortion is very high right at both crossover points (around 270Hz (mid-range) and 2700Hz (tweeter)) at both 86dB and 96dB SPL/1m, exceeding 3% at the mid-range crossover. Minimum impedance dips to 3.4 ohms with a possible resonance around 500Hz visible in the impedance/phase curve. Discontinued.
How it compares: Just above it: Dynaudio Emit M10 - $56 cheaper, 0.5Hz higher bass extension (-3dB). Just below it: Acoustic Energy AE100 Mk2 - $457 cheaper, 1Hz higher bass extension (-3dB).
