I'm novice- so go easy on this: I want to build something custom. I was thinking of the following drivers to make up each channel:

1 slot (2 total)
1 smith with a 2435 compression driver (2 total)
1 (or 2) 2122H drivers (2 or 4 total)
1 2245H 18" sub (2 total)

Each driver will get a seperate enclosure (slots will be bracket mounted). The smith either on top- or (can I squeeze it in any other way- vertical???)

Here are my questions:
1. I've pretty much got a 4345 here with a substitution in the horn. Will this combination work well together?
2. Besides the 3107- Is there an existing crossover network that would do well enough for this group (until I get a better one)?
4. I plan on bi-amping (initially) and tri-amping or even quad-amping eventually. I'm confused about crossover topology- If anyone is willing to help me put together a nice crossover configuration for this project -I'll pay (send me PM)..

Thanks!!
