Two glued enclosures.
A crossover ready for installation. It's a very SET-friendly first order consiting of an inductor in series with the woofer and a capacitor is series with the tweeter. A resistor is placed across the tweeter leads to damp any resonance. I used a copper foil inductor because I had in in the parts bin, but the copper wire inductor supplied with the kit will work just as well.
