To operate in bi-amplification with the JBL XPL-200,Can I use a crossover JBL 5234A or 5235 or M-552 ,what brand do you recommend.
For the DX-1 is found.
The frequency is 300Hz or 400hz to use?

I believe it's 290 Hz.
Possibly 250...I don't have mine bi-amped anymore due to the home theater bug.

I just used a Crown VFX-2A.
