| There are some serious problems with the DIY servo control. It keeps the frequency response flat down to 20 Hz, but the THD is rocketing at the same time. There is also a strong peak at ~65 Hz. Group delay and spectral decay are affected by the multiple resonances over the whole pass-band. Spectral contamination test shows lots of distortion. + Good extension + Low group delay - Extremely high distortion - Max SPL capability - Lots of ringing in mid and upper bass range | ||||
