Are the tweeter circuit and the woofer circuit always interconnected?   Reason I ask is that I was watching the encore Bravo video and the drawing looked like the woofer circuit was seperate but when Danny put it together it all looks interconnected. 

Also do I need to screw the crossover board to the bottom of the speaker? 

Do you need standoffs due to the zip ties?

In a sense, as both circuits share the same input connection terminals.
To their input is shares as are their connections to the negative line.

The networks splits the positive input into treble and bass signals, then they converge back together on the ground line.

The only way to completely separate them would be to use a binding post with 4 connections and jumpers between the two positive terminals, then the negative terminals you would see in bi-wire/amp capable speakers.

Here's a visual of what Hobbs is mentioning.   While not Encore's, the concept is the same (single woofer and single tweeter - A/V-1RS aka X-on Wall).   Mine started out as two separate circuits, but were tied together at the cup (input):




And you can either screw them, or do what I did and use some 3M Duo-lock.  Those suckers will not budge even if you want them to.
