The Two Speakers In Full
KEF Q Concerto Meta: $1,399.99 per pair Amazon Crutchfield eBay
Pros: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Directivity holds remarkably steady from lower treble into upper treble, where many similarly-priced speakers narrow sharply as frequency rises: one of the reviewer’s top 10 picks under $1,500. Measured bass extension of 53Hz (-3dB), with a measured sensitivity of 84.2dB.
Cons: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment. Needs to be pointed closer to on-axis rather than heavily toed out: combined with its rolled-off, shelved-down top end, too much toe-out makes it sound noticeably dark.

StarkSound Beta 5: $499.00 per pair Amazon eBay
Pros: Impressive bass extension for the price: F3 at 52Hz, F10 at 37Hz, reaching down to 40-50Hz in-room with solid kick-drum impact. Good harmonic distortion control at both moderate and loud listening levels. Solid build with a thick polycarbonate baffle meant to reduce cabinet resonance. Measured bass extension of 52Hz (-3dB), with a measured sensitivity of 83dB.
Cons: Sensitivity undershoots its own spec: rated 86dB, measured closer to 83dB. A resonance artifact shows up independently in the on-axis response, burst decay, and impedance measurements, hurting directivity. Multitone distortion spikes to about 10% in the 800Hz-1kHz range, tied to woofer excursion: a subwoofer crossover helps. Needs to sit close to the wall (about 10 inches) or be EQ’d if placed further out, since the midrange sounds thin and the treble boosted otherwise.
