Ah the berauty of having your own business and ABN

lol, not really that beautiful, Uni student + Business just means, I make no money. But I occasionally save on things when I need them, but then I lose that saving when I pay for all the stupid returns on broken stock and all the other rubbish that happens. I dunno why I bother.

Learning process

Just went and picked up some new Barry Adamson to test the new speakers when they're done. Yay!

Just working out what I need to order for the crossover... but all the values are between values that I need and stuff...

With these selections, can I add the following two values after each, to make the desired... or is it just a 'close enough' kinda thing?

This should be all I need I think, for a 2nd order Butterworth highpass, at 2700, and 2nd order Butterworth lowpass at 2700. And a zobel and -3dB L-Pad. I think.

About to order some premade PCB's some sticky felt, and some bitumen felt.

Zobel Network.
Capacitor 16.349 uF = 15 + 1
Resistor 7.25 Ohms = 6.8 + .47

Highpass Crossover.
Capacitor 7 uF = 6.8
Inductor 0.5 mH = 0.47 + 0.03

Lowpass Crossover.
Capacitor 5.2 uF = 4.7 + 0.5
Inductor 0.66 mH = 0.68 + 0.03

Attenuation Network.
Resistor1 1.75 Ohms = 1.5 + .22
Resistor2 14.5 Ohms = 12 + 2.2

You don't need the 0.03 inductors. The drivers will have + / - 10-20% variance, as long as the crossovers are within 5% of the specified value, and the "channels" match you will be good with just the 0.47 mH.

Damnit! I was making the crossover and somehow snapped the wire off the Capacitor with nothing to spare at all, cut about 2 mm into the capacitor to make a hole to solder a pole to, that worked for two days, fell off.
