#14 DIYSG HTM-12 v2: $920 per pair per kit Discontinued DIY Sound Group eBay
Older model: the DIYSG HTM-12 v1 (ranked lower, rated 3.8/5). See every DIYSG HTM-12 generation.
Pros: A high output home theater kit with a 12 inch woofer and horn tweeter, very low distortion, and an easy load for most receivers. 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. Measured bass extension of 67Hz (-3dB), with a measured sensitivity of 91dB.
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. Discontinued.
Is the DIYSG HTM-12 v2 right for you?
Buy it if
- you have a modest amplifier (91 dB sensitivity is easy to drive).
Skip it if
- you want to buy it new: it is discontinued.
