Array 1400 Using Stock SAM1HF, LE14H-3, and passive 2-way Crossover?
I have started an Array 1400 clone project. I have a pair of SAM1HFs and LE14H-3s, and I would consider making something like the SAM12x passive crossover but for use with LE14H-3. That may be good enough (for me) along with the stock SAM1HF crossovers. And less expensive and quicker to get up and running.
Has anybody tried using the SAM1HF with its stock passive crossover with a modified SAM12X or home made SAM12X-type crossover for use with LE14H-3's for the woofers?
I have collected a lot of info about the array 1400 clone projects here. I have found the schematics for the array 1400 crossovers. I was thinking of making the array 1400 low frequency crossover and adding a high-pass to feed the SAM1HF. Would this be worthwhile?
Anyone have schematics for the SAM12X crossover?
Another quick and dirty approach would be to use an active crossover and bi-amp. Any suggestions would be appreciated.
The goal is to make a high quality speaker for 2-channel audio.
Air core inductors worth it?
I guess there are really no shortcuts, and I don't want to compromise the performance.
I think this is the correct schematic for the stock Array 1400 crossovers.

I've been putting together a parts list and finding the components.
I saw a picture of the Array 1400 LF crossover which uses air-core inductors. In pictures of your (Robh3606) crossover I noticed some ferrite core inductors. How important is the core type for the large inductors in these crossovers? Is low DCR more important? The 14 gauge air core inductors available have a DCR of about 0.52 ohms, and the schematic shows a DCR of 0.45 ohms, is the difference significant enough to go to 13 gauge wire inductors or switch to ferrite core inductors with lower DCR?

Just build stock 1400 networks or charge couple them for the 435 and 045. To bi-amp you need custom voltage drives that Greg Timbers has already been kind enough to provide. I built my 1400 Array's from scratch using Be components. Best thing to do is use the stock network with that component set. Rob:)
