Just a quick question Nelson - what oscilloscope display settings do you use to show the 1 watt (or 5 watts) power level? Many thanks!
You mean at the output of amplifiers?
The 1 watt window is 1 volt/vertical division, shows +/-4 V peaks which is 2 W
peak, which is what a 1 watt amp can do...

You beat me to the question although you avoided asking it directly. Where's our crossover? Wait, I meant to say, when will you be sharing your crossover with us? 

My Apogee Divas are starting to whine like a puppy wanting to go outside
When do you think we can open the door ?

Can this crossover be setup for non-standard slopes, not only Butterworth or Linkwitz-Riley but more like Bessel? I understand that it will take some fiddling setting the slopes anyway as it may have potentiometers and not fixed resistors.
I assume that is simply a matter of changing to appropriate filter Rs & Cs. As i understand it, 1st order to 4th order and the nature of the rolloffs controlled by the passive parts. This should be a very versatile device.

I must send you one.
The crossover has a high-pass and low pass jumper selectable for 6, 12,
18 and 24 dB/octave. The frequency of each pole is independently
adjustable with on-board pots for 2 octaves - 1 octave on each side of a
center value set by the capacitor. In "ordinary" use, all caps are the
same values. The board accommodates pcb-mount connectors and level
pots, or wires can be run to external components.

I would love that.
I have everything else ready. Speakers, bass amp, SIT-3.

This sounds great!
Thanks Mr. Pass! We all try to imagine how busy you are. And then always

Of course, but it will need some fiddling to create non-standard curves/slopes. Many speakers do not use standard slopes like my Magnepan.

Yes. That's why the R values on each pole are variable 4:1 range. I think
most of what you might want will be doable without changing the caps
if you pick the appropriate center value for the cap/frequency.
