HT-12 v2a Measurements

Full measurements for the DIY Sound Group HT-12 v2 speaker kit.

This is the 2022 update to the HT-12 design where the woofer was change from Eminence to Celestion.

These measurements are taken with the advanced crossover which uses additional components to improve the frequency response linearity.

See here for measurements of the design using the standard crossover.

The following measurements were performed on my 10' tall outdoor turntable, measurements taken at 2.83v / 2M on the tweeter axis and scaled 6dB to approximate 2.83v/1M level. The measurements were gated at 14ms and blended to diffraction adjusted nearfield woofer response below ~250hz.

No smoothing applied to the frequency response measurements.
