I have to agree with Doug on this, get either one, but not both. I have both
the 400Hz and 250Hz and I saw little difference between them. When I
installed my KRX3 I took the 400hz filter out of the main receiver and moved
it over to the 2nd receiver. I am happy the way it works now. So, that's
2.7Khz and 250Hz for the main receiver and 2.7Khz and 400Hz for the sub.
Diversity receive still works fine. YMMV.
