drop me a note if you'd like to experiment - i have a marchand that didn't leave when i sold my subs.

The Marchand crossovers are very well regarded in the hardcore DIY community. The maker can supply the owner replaceable "cards" to insert in the x/o, providing just about any x/o frequency and slope one desires. And most are available with balanced XLR jacks, unlike the similarly-priced First Watt B4, another fine unit. The B4, unlike the Marchands, contains no Opamps, achieving filtering via all discrete parts. The B4 also needs no extra-cost filter cards, having internal dip-switches to set frequency and slope characteristics.
Thanks guys for the responses so far. bdp24, I believe you are talking about Marchand's active crossovers but I am not interested in putting another active component in the signal chain. Thank you for referencing the First Watt B4. Even though it is an active device, it was still interesting to read the manuals by Pass. It would be interesting ot me if he would offer a passive kit that the user could stuff with their favorite caps and resistors, and to provide some technical information on component compatibility and matching subs to the main speakers.
I have not yet read anything saying the Marchand passive high pass filter is exceptional, or does nothing unwanted to the signal. Instead, what I have mostly read is that some prefer the Marchand high pass to doing nothing because they believe reducing the demand for the main amplifier to drive low frequencies improves clarity in the upper frequency ranges. The flavor of most of the posts seems to be that one way or the other is a lesser of two evils.
I am really interested in hearing from folks with a high end and resolving system who are using monitor type main speakers mated with subs, and the method they have found to best cross over the subs to the mains.
One advantage I have is that my subs and main speakers come from the same manufacturer and are made to work together. There is an option to use a crossover within the subs to high pass the main signal so that is something else I can at least try, particularly if I position the subs near the main speakers so the second IC from the subs to the mains would be short.
Now that I have finally received the main speakers, second sub and stands for everything, I will contact the manufacturer to verify their recommendation for the best way to integrate the high and low frequencies. Would still appreciate hearing about success stories.
