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.
