Phase response
The phase response obtained is shown below. At this stage, optimisation was stopped but further
corrections could provide minimum phase up to the 20kHz with just a few extra zeros.

Subjective evaluation
Comparative listening tests on the test system show exactly the strengths and weaknesses that
were expected based on the acoustic set-up. Mixes are picked apart with great ease (too much so,
perhaps, for home use), and the subtlest of EQ changes become very obvious. Stereo imaging is un-
characteristically good, in all 3 dimensions, for the low-cost drivers used. Good floor covering would
be advisable on account of the symmetric dual woofer arrangement of the loudspeaker. Taking full
advantage of the added flexibility of DSP correction should permit a greatly optimised compromise
between on and off axis responses by gearing cabinet design towards an improved radiation pattern,
and having the DSP correct consistent response errors.
