#121 Harbeth Monitor 30: $3,200 per pair Discontinued eBay

Newer model: the Harbeth M30.3 XD2. It’s likely to perform similarly, though we can’t confirm that yet.

Pros: Sensitivity of 85dB and a 6-ohm nominal impedance (150W handling) make it reasonably easy to drive despite the impedance dropping to about 4.8 ohms at points. Wide bandwidth 2-way design with a 7.9” bass/midrange driver and 1” soft dome tweeter. Measured bass extension of 64.5Hz (-3dB), with a measured sensitivity of 87dB.

Cons: CEA2034 spinorama shows a significant on-axis dip starting around 3kHz at the crossover point, which the reviewer called “the classic engineering work of calling a defect a feature” rather than the intentional character it’s often described as. Predicted in-room response is uneven with an exaggerated tilt toward high frequencies. Step response shows the tweeter and woofer out of phase with each other. At $3200 per pair, the reviewer concluded the price doesn’t match the measured performance. Discontinued.

How it compares: Just above it: Cerwin Vega LA165 - $2934 cheaper, 0.8Hz lower bass extension (-3dB). Just below it: BIC America DV62si - $3035 cheaper, 2Hz lower bass extension (-3dB).
