What this page covers. The DIYSG models ranked here span passive speakers, including DIYSG HTM-12 v2 and DIYSG HT-10. Use each model’s category position to compare it with alternatives of the same size and use case.
This page lists all 2 DIYSG speakers ranked on this site across passive speakers. Each model is shown in the category where it competes, with its current rank and the size of that ranking.
Use the category position rather than the brand name alone: speakers from the same manufacturer can perform very differently by size, price and product family.

Ranked #14 of 131 in Large Size Bookshelf Speakers - DIYSG HTM-12 v2: Availability varies DIY Sound Group eBay
Pros: Purpose-built high-output cinema kit pairing a 12-inch woofer with a compression driver in a large SEOS waveguide. Erin measured 91dB/2.83V/1m sensitivity, extraordinarily low distortion (still below 1% to about 60Hz at 102dB) and only about 0.5dB tweeter compression at the same level. Horizontal directivity is consistent and crossover integration is unusually good, so response corrections remain EQ-friendly. The benign impedance curve can be driven by many capable AVRs.
Cons: Erin measured F3 at approximately 67Hz, the normal efficiency/bass-extension tradeoff of a high-sensitivity 12-inch design, so a subwoofer is mandatory. A few narrow resonances appear in the response, impedance and decay plots; Erin suggested crossover/component investigation could improve them. Vertical radiation narrows around the crossover, the unfinished kit requires cabinet assembly and finishing, and its broad baffle is visually and physically substantial.

Ranked #98 of 131 in Large Size Bookshelf Speakers - DIYSG HT-10: $248/each DIY Sound Group eBay
Pros: 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. Sound-power smoothness of 0.197 is solid for a budget DIY kit.
Cons: 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. It ships as a flat-pack cabinet kit requiring assembly, sold in a minimum order of two units.
