In Reply to: Nagging question about op amps in active crossovers posted by kurt s on January 24, 2007 at 10:07:20:
...then they must be really amazing speakers!So they must sound even better - perhaps far better - without the opamps.
Most times in C/O's, opamps are simply used as either +1 or -1 gain buffers and this can be done far better sonically by a single discrete part, i.e. a jfet or a tube. But if you want to have it sound really good - then that part needs a CCS load and also bootstrapped if a CF or SF, which makes it more complex - but so what? His speakers are not exactly simple (or cheap) to build either.
But a good word for him - I am using a DIY version of his dipole subs with my ESLs and they are GREAT with a (lucky chance) passive crossover!
I will not use an opamp anywhere in a signal path, not even in an AM radio!
