Just give them the part number for the xover and the terminal plate detailed on the first page of this thread and they'll do the rest.
Also, the HPR-153i is active but uses the exact same drivers which is why I believe you can use the xover if you're going to either make a passive HPR-153i or convert one to passive. Of course, the xover will have an extra connection for a second woofer left over.
The HPR-153i looks like it uses an all-in-one design for the amp, xover, and dsp so there is no separate xover that can be ordered... only the amp section.
