#2 Perlisten S4b: $8,000/pair Perlisten Dealer Locator
Pros: Reference-grade directivity and output from a compact sealed monitor. Erin called its radiation behavior the smoothest he had measured: Perlisten’s DPC array—beryllium tweeter between two midrange domes—shapes vertical output while transitioning cleanly to the 7-inch woofer. Harmonic distortion remains below 1% at 86dB and, above 100Hz, also below 1% at 96dB; compression is exceptionally low. The response is highly linear, the midrange was a listening highlight, and the sealed F10 of 40Hz provides a predictable slope for subwoofer integration.
Cons: Erin measured only 84.5dB sensitivity and an impedance minimum just under 4 ohms, a difficult efficiency/load combination that deserves substantial clean amplification. Its 78Hz F3 means a subwoofer is effectively mandatory for full-range listening despite the 40Hz F10. A roughly +3dB feature around 10kHz appears on-axis, though Erin did not find it objectionable. Price is extreme for a stand-mount and the tightly managed vertical radiation makes correct stand height important.
How it compares: Just above it: TAD Compact Reference One (CR1TX) - $79500 more, 1Hz higher bass extension (-3dB). Just below it: KEF Reference 1 Meta - $2000 more, 2Hz lower bass extension (-3dB).
