It is most certainl easier to experiment with passive crossovers unless you use a digital active crossover, and that is not likely a future product. Passives can be build in minutes with clip leads.
The slopes/freq points aren't hard to adjust, but implementing different notch filters in an active XO is a nightmare.
Hopefully a hybrid approach can be done with active slopes only...
I've had a hard time with anything but first order. Active doesn't steal as much energy. No matter how much you think you know about crosssovers something else always rears its ugly head. Experts at crossovers also turn out not to be so that is also a problem. I like the simplicity of 1st order but like the steeper 4th order slopes. Active doesn't require an order from parts express to experiment. Perhaps I should just find a Marchand and go from there.
Crossovers make me grumpy am I the only one?

I get grumpy about them too. Lucky for you, you could change some parts in your Bottlehead amps and end up with your first order two way crossover. The low pass would involve adding a tiny bit more to the circuit, but you could do it. In the high pass section, you would only need to change the coupling cap, and optimize the parafeed cap to keep any 60hz out. If you are interested, let me know.
Yeah I do get grumpy when it comes to crossovers : ) I may inquire about this later. Didn't know you could do it this way. Very interesting.
