Some DSP fun with a acoustic suspension speaker and the dspNexus 2x8.

Have a pair of 2-way speakers for some trials.  Lets just call them the M1 speakers. 

First thing was looking at the nearfield woofer response and it has two areas that need work.  One is the dip at 650Hz and the other is the low frequency bump at 80Hz in the green curve.  The orange curve is after the corrections are applied.

Next is farfield on-axis measurement of the speaker to see how the woofer and tweeter integration.

Next was to make an on axis 1m farfield measurement to see how the woofer and tweeter integrate.

The crossover is at 2200Hz with a Linkwitz-Reilly 8th order crossover.  The woofer EQ is still running as well.

After some level matching, here is the result.  Still need a longer free space measurement to eliminate some reflections, so just looking from 800Hz up.

Here is the next stage of the project for these speakers:
