I recently lugged these beasts into the house after working out a trade with a fellow AK'er. They sound quite nice as-is, but they appear to be all original, so I'd like to rebuild or make new crossovers incorporating the Tobin mod.
Driver arrangement consists of B199A woofers, B200A mid, and B200Y tweeters. The crossovers appear to be original.
I have a few questions before I begin gathering parts:
Here are some pics inside the cabs and one of the Tobin 104T:

I have a few questions before I begin gathering parts:
- Is the Tobin 104T crossover plug and play for my application?
- It appears I'm missing the bowls that cover the back of the midranges. I've read to use a Tupperware container, or something similar, and line the interior with batting. Should I be looking for a container with a certain volume? And what type of batting is appropriate?
- How do I tell if my mids are wired in phase? Tracing the wires from the mid to the xo, the "1" terminal on the speaker is connected to the "1" terminal on the xo.
