I'm new to cabinet building, but not to woodoworking. I'm planning on building a 1x12" cabinet, and already have an Eminence Deltalite 2512 II coming from ebay. I'm tempted to model this cab after the successful Genz-Benz Neox 112T, which is simply a version of the Onken speaker design, and shouldn't be too difficult to construct. My question is about the tweeter and crossover in such a cab. The Neox has a 100 watt compression bullet tweeter, and a Butterworth 4 kHz crossover. If my amp is supplying 300 watts, what is protecting the tweeter? Is it simply a series resistor making a voltage divider? Seems like a waste of power. Unlike a piezo, the compression tweeter has a resistive load (8 ohms). How is this wired with the woofer, and how does this load appear to the amplifier? What influence does the crossover have on the load the amplifier sees? The other option is to use a piezo tweeter array ala BFM, since they are cheap and don't require a crossover. Do I need the same number of piezo tweeters to equal my expected power handling requirements. For instance, I want it to handle 300 watts: is that 6 50-watt piezos? Do I need to include any additional protection elements? Sorry for the long post, but I'm trying to be specific so as not to waste anyone's time.
