Any resources for Active crossover building?

Active Filter Cookbook (Don Lancaster):

IC Op Amp Cookbook (Walt Jung):

http://www.amazon.com/Op-Amp-Cookbook-3rd-Walter-Jung/dp/0138896011

Another aspect that might be useful, is possible power supply designs for running op-amps, since they need, usually, +12 and -12 volts or something similar. Here's a reference to DC-DC converters, which are the devices needed to do this:

http://en.wikipedia.org/wiki/DC_to_DC_converter

NOW... IF your amp has 'phantom power' output, like many old-school Orion and PPI amps, then you're "in like Flint'". Those amps have +15V and -15V available at the phantom power DIN plug. Many of us have built active crossovers, running off of these as a power source...
