Harbeth M30.3 XD2: $6,290 per pair House of Stereo eBay
Older model: the Harbeth Monitor 30 (rated 2.5/5).
Pros: The current version of Harbeth’s Monitor 30, with an 8” (200mm) RADIAL4 mid/bass driver made by Harbeth and a 1” ferrofluid cooled tweeter in a compact front ported cabinet. Harbeth rates it at 50Hz to 20kHz within 3dB in free space with the grille on, and a 6 ohm load that it describes as easy to drive, with amplifiers from 25W per channel suggested. Handmade in England and offered in five real wood veneer finishes.
Cons: No independent measurements have been published for this version, so its linearity, directivity and real bass extension are unknown. The older Monitor 30 measured with a deep on axis dip around the crossover region, and it isn’t known whether this revision changes that. Sensitivity is a modest 85dB at 2.83V, and the 50Hz lower limit means most rooms will want a subwoofer for deep bass. Harbeth tunes it for placement away from walls, and it costs far more than most 2 way standmounts.

Perlisten R5m: $6,590 per pair Audio Advice eBay
Pros: The standmount version of Perlisten’s DPC-Array platform (three silk-dome drivers plus dual 6.5” woofers), reaching a measured -6dB point of 50.5Hz. A directivity-index standard deviation of 3.01 is tight for a standmount this size. THX-adjacent R-series build quality at a lower price than Perlisten’s S-series. Measured bass extension of 61.7Hz (-3dB).
Cons: On-axis deviation of 0.264dB and sound-power smoothness of 0.511 are middling, with a fairly pronounced -0.29dB per octave downward tonal tilt and a bass-alignment Q of 2.40 pointing to a somewhat resonant low end. Like the rest of the R-series it’s sold only through specialty AV dealers with per-unit pricing.
