Question for Pano: JB's 605 OB crossovers
I grabbed a copy of the schematic you posted on the crossovers
you used with John Busch's open baffle 605A speakers at LSAF
last May. I am using Jeff Markwart's design on my 605B OBs and
thought I'd try the fixed attenuation with HF compensation
you show in the LSAF design on the tweeter side. I'm curious why you
have the 10uf cap in parallel with the 4 ohm resistor on the ground
leg? It looks like it would have no effect as all frequencies that made
it though the 2nd order filter would be a good octave higher. Is this
intended to put a steeper, shelved cut from say 800 hz or so?
I've attached that schematic. Not sure how it will appear.
Thanks,
