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

Link to the forum thread for this design

The following measurements were performed on my outdoor turntable, measurements taken at 2.83v / 2M just below the tweeter axis and scaled 6dB for approximate 2.83v/1M level.

Measurements gated at 10ms and blended to nearfield woofer response below 218hz. Smoothing applied is 1/48th octave.
