Short answer: the KEF Q Concerto Meta. It ranks #11 of 131 bookshelf speakers by sound quality, rated 4.6/5, at $1,399.99. The DIYSG HT-10 ranks #98, rated 3.3/5, at $496, $903.99 cheaper, which does not close the gap in sound quality.
The case for the KEF Q Concerto Meta: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Watch for: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
What the DIYSG HT-10 does well: A distinct kit design from DIY Sound Group’s HTM-12 v2, a 10” ported LCR/surround box built around a Celestion woofer and compression tweeter. The catch: On-axis deviation of 0.537dB is rough, with a pronounced -0.43dB per octave downward tilt giving it a notably dark tonal character, a somewhat resonant bass-alignment Q of 1.76, and the Harman in-room bass extension estimate is a modest 56Hz for a 10” woofer.
Buy the KEF Q Concerto Meta. It is rated higher for sound quality, and the $903.99 you would save on the DIYSG HT-10 does not close the gap.

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.
