Altec N809-8A Crossover

[THD+N]

Roccus asked me for assistance with a crossover, so I thought I would share my opinion so everyone could see;

I would suggest making a clone of the Altec crossover that was designed for your driver and horn. You'll need three parts for each cross-over (left and right):
Supplier: Parts Express
8 ohm L-Pad, part number: 260-255, $10.90 each
Dayton Audio 18uF/250V cap, part number: 027-434, $6.47 each
Jantzen 5280 2.2mH inductor, part number: 255-130, $7.71 each

With this crossover those drivers and horns will sound awesome.

Thanks again Nick... this looks like it is all coming together and at a very nice price....

In the future, if you want to upgrade the crossover, you can experiment with higher slope crossover points to increase power handling and better sound quality.

So this is what I will build, correct?

Bulb or Fuse?

I know my schematic looks like a fuse but I plan to use a protection bulb when I drew it up I was toying with fuse or bulb but think I will go with a bulb, also as Nick pointed out there is a 3rd terminal on the Lpad that will go to ground...
