Inside the B2031P
Here's a look at the Behringer monitor. I'll get some stuff to do modifications and see if it makes a measurable difference. I'm going to try and generate some plots using the new REW so we can get a better look at resonance issues. The crossover looks like a minimalist WGed 2-way with just a cap and resistor in the tweeter with a 2nd order low pass. The active version should do much better in this regard even though there's not a huge problem in the passive version. We see poly caps, an iron core inductor, and a wirewound resistor. The baffle is stout on the woofer half, but thinner on the tweeter. Enclosure damping is certainly less than I've ever used. That may be where we could best improve the design.
EDIT: The break up is benign on this cone! Response issues are caused by the enclosure/ports next to the tweeter.
