Parts Express has just come out with a new very low cost DSP option that can be used at home or in a car. I will be getting one soon for test. Later this year I will be testing the "eggs" with three scenarios. The first will be using the passive crossover and one amp. The second will be using the passive crossover and one amp but with DSP correction based on the frequency division to the drivers as determined by the passive crossover. The third will be a full tri-amped setup with maximum control of all functions by DSP. At the entry level I will be using the new DSP-408 from Parts Express. At the higher end I will be using my DEQX Express II and hopefully also a Wavelet processor from Legacy Audio. Should be interesting and when I get to the testing point I will need some volunteers. Here is a link to the DSP-408:
