HT-8 Measurements

Full measurements for the DIY Sound Group HT-8 speaker kit.

Link to the forum thread for this design

The following measurements were performed on my 10' tall outdoor turntable, measurements taken at 2.83v / 2M just below the tweeter axis (bottom screws on the waveguide) 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.

Smoothing applied is 1/48th octave.

Other Notes:

Updated graphs for the 2022 crossover revision which was a minor adjustment to correct for a small level disparity noticed on the newer batches of woofers.
