Short answer: the Klipsch RP-600M II. It ranks #123 of 222 bookshelf speakers by sound quality, rated 3.7/5, at $449.99; the DIYSG HT-10 ranks #168, rated 3.3/5, and costs $496, which makes this an easy call rather than a real tradeoff.
The Klipsch RP-600M II is the more accurate option. Bookshelf speakers with a large horn tweeter, wide soundstage, high efficiency and bi-amp ready terminals. Its measured preference score, a predictor of how neutral it sounds, is 5.64 against 4.26 for the DIYSG HT-10. The tradeoff: On-axis, the treble runs notably hot (even hotter than the original Klipsch RP-600M in some respects) and needs about 20° of toe-out or the grille installed to sound balanced.
What the DIYSG HT-10 does well: A budget DIY flat pack kit with a 10 inch woofer and compression tweeter, built for home theater front or surround duty. The tradeoff: 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 Klipsch RP-600M II. It is rated higher for sound quality than the DIYSG HT-10 and costs less, which makes it the one to get unless you need something the other one does better.
