Misc. Information
If you buy two kits, you can use them to build a nice set of small towers, or a bookshelf speaker design. Then use the vertical layout for best performance.
-
- Cabinet requirements are pretty basic, you should be fine keeping it around .5 cf. Ported works well for these woofers.
- Wiring; the crossover to the speakers is very straight forward. We putting the woofers in series. Take the positive lead from the crossover and connect to the positive terminal of woofer #1. Then you will need a length of wire. This wire connects between the negative terminal on woofer #1 and goes to the positive terminal on woofer #2. Finally you run a lead from the Woofer Negative terminal of the crossover to the negative tab of Woofer #2.This completes wiring the woofers in series.
- Hooking up the tweeter is easy, you run a lead from the crossovers Tweeter positive terminal to the positive tab of the tweeter. Then from the crossovers negative Tweeter terminal to the negative tab of the tweeter.
- For best response use a tweeter centered design ( Horizontal Layout ), see picture below.
