Misc. Information
- Cabinet requirements are pretty basic keep it about .4 to .5 cf. and you should be fine, ported if you want or sealed either will work.
- Wiring, the crossover to the speakers is very straight forward, we will be putting the woofers in series. The red leads from the crossover are for the woofers, the solid red lead is positive. We take it and connect to the positive terminal on woofer #1. Next you will need a length of wire to run from the negative terminal on woofer #1 to the positive terminal on woofer #2. This leaves you with a red lead with a stripe, it connects to the negative terminal on woofer #2, you have wired the woofer in series.
- Hooking up the tweeter is easier, you use the blue leads from the crossover for this, the solid lead goes to the positive terminal on the tweeter, the blue lead with the stripe connects to the negative terminal on the tweeter.
- For best response use a tweeter centered design ( Horizontal Layout ), see picture below.
