HT-12 v2b Measurements

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

These measurements are taken with the standard crossover.

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


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 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.


I also took a full additional set of measurements with the ports sealed, these can be found here.
