ELAC BS U5 - ranked #36 of 63 Medium Size Bookshelf Speakers · Editor's rating 2.9/5

#36 ELAC BS U5: $856 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.

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: JBL Stage 2 250B - $506 cheaper, 3Hz higher bass extension (-3dB).
