Short answer: the Selah Audio Purezza. It ranks #25 of 84 bookshelf speakers by sound quality; the JTR Noesis 210HT ranks #39.
What the Selah Audio Purezza offers: 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 offers: 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 Selah Audio Purezza if sound quality matters more than the price. Buy the JTR Noesis 210HT if the price matters more than sound quality.

The Two Speakers In Full
Selah Audio Purezza: Contact manufacturer Selah Audio
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.
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.

JTR Noesis 210HT: $1,999 each JTR Speakers
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.
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.
