See these links:
The only other stuff you need is some short speaker wire and crimp terminal ends if you don't want to solder to the crossover. Also, you'll need some short screws to mount the crossover inside your speaker cab. The rest is pretty intuitive, pos/neg inputs to the crossover from your speaker jack and pos/neg outputs to the woofer and tweeter. Optionally, you can line your cabinet with eggcrate foam to help control internal resonances to help flatten out the response a bit, but you can play around with that later. This is more important if your cabinet is sealed or mostly sealed. Not really required for an open back.
Maybe try converting just one cabinet first to see if you like it. If you need any help, give me a holler.
Hi @Klappy,
I realize this is an old thread, but I happened to stumble upon it. I use a XiTone 1x12 Passive wedge, which features the Eminence BETA-12CX and ASD:1001, as well as the specific cross-over you listed. However, I noticed you linked to the bolt-on version of the HF driver, which is the ASD1001B. Was that a mistake? I assume you would want the standard, threaded 1-3/8" ASD1001(S) for direct screw on connection to the BETA-12CX.
Cheers,
John.
