Short answer: the JTR Noesis 210HT, if you are buying new. The Selah Audio Purezza ranks higher than it (#30 vs #40 of 131 bookshelf speakers, 4.4/5 vs 4.3/5) but is discontinued, so only consider it used; the JTR Noesis 210HT is still sold new at $3,998.
What the Selah Audio Purezza does well: Premium two-way built around Purifi’s exceptionally linear 6.5-inch woofer and a tall RAAL ribbon. Watch for: The ribbon’s tall aperture creates deliberately narrow vertical radiation (roughly 20-30 degrees around 7kHz), so stand height and listening elevation are critical.
What the JTR Noesis 210HT does well: Exceptionally high-output sealed loudspeaker: Erin measured 92.5dB/2.83V/1m sensitivity, less than 3% distortion at both 86dB and 96dB test levels, and excellent compression behavior. Watch for: Erin measured F3 at 76Hz and F10 at 43Hz, so the 210HT is designed to hand bass duties to subwoofers rather than operate full-range.
Buy the JTR Noesis 210HT, since the Selah Audio Purezza is discontinued and only worth hunting down used.

Selah Audio Purezza: $2,950 per pair Discontinued Selah Audio eBay
Pros: Premium two-way built around Purifi’s exceptionally linear 6.5-inch woofer and a tall RAAL ribbon. Erin measured about 85dB/2.83V/1m sensitivity, a 4.7-ohm minimum and the lowest midrange nonlinear distortion he had measured at the time. It reached roughly 103dB at 1m with little audible strain; horizontal response is smooth and broad, and Erin’s 200Hz low shelf (+3.5dB, Q 0.7) flattened the lower-mid/bass balance effectively. Measured bass extension of 86.0Hz (-3dB), with a measured sensitivity of 85dB.
Cons: The ribbon’s tall aperture creates deliberately narrow vertical radiation (roughly 20-30 degrees around 7kHz), so stand height and listening elevation are critical. Erin found a directivity change around 1-2kHz, a feature near 4kHz, and insufficient baffle-step compensation below 200-300Hz in his sample. The 4.7-ohm minimum and modest sensitivity favor a separate amplifier. A subwoofer crossed near 80Hz is recommended for distance and output. Discontinued.

JTR Noesis 210HT: $3,998 per pair JTR Speakers eBay
Pros: Exceptionally high-output sealed loudspeaker: Erin measured 92.5dB/2.83V/1m sensitivity, less than 3% distortion at both 86dB and 96dB test levels, and excellent compression behavior. The coaxial compression driver and dual 10-inch woofers cross at roughly 850Hz into a nominal 60° x 60° pattern, keeping radiation controlled enough that broad response errors remain amenable to EQ. Its sealed 12dB/octave bass roll-off simplifies subwoofer integration, while Baltic-birch construction and professional-grade drivers suit reference-level cinema use. Measured bass extension of 76Hz (-3dB), with a measured sensitivity of 92.5dB.
Cons: Erin measured F3 at 76Hz and F10 at 43Hz, so the 210HT is designed to hand bass duties to subwoofers rather than operate full-range. The impedance falls to approximately 3 ohms through 100-200Hz (Erin), making a stable separate amplifier preferable. Midrange resonances and the horn-to-woofer directivity transition raise the predicted in-room treble balance; careful toe-in, room treatment and DSP are advisable. Each enclosure is unusually large and heavy for a stand-mount, and the narrow coverage is less forgiving across a wide seating area.
