    I'm pretty sure the Fostex parts I got came from the Fostex Pro Monitor speakers -
    they even came with the upright mounts for time aligning the drivers.
    The Mid horn driver has a Lab Series D252 label. The round nose super tweeters I got
    don't have a label but looks identical to the T825 tweeter I've seen in their catalogs.

    Here is a clean copy of just the crossover drawing I got ...
    Again, this is a hybrid design for bridging a JBL 2214 woofer to the
    Fostex Pro Monitor tweeter and Fostex mid horn pair.

    Also (fwiw), the network in the pic that I posted above is purported to be 2/3's of the LS3 network ( > for the horn/driver & tweeter ).

    Here it is again;

    I am sorry for a very late reply. I have not been on this site for quite a while (I broke my back but have healed now! ).

    As someone else has pointed out, the dividing networks for our studio monitors are specific to our proprietary drivers and mounting. Your mileage may vary.

    But I get many such inquiries and have no difficulty posting the details here.

    The actual capacitors and inductors we used were all proprietary "Fostex" brand which will likely be hard to get now. I recommend using high-quality components such as SOLEN at this point in time.

    PS. You can get my attention much more quickly in the future by emailing me directly at [email protected] or leaving a message at 204.943.9000

    PPS. Pay close attention to the polarity of the driver connections!

    Hi Michael
    When I saw the ad, I was immediately thinking of you. This was your baby after all. And I see those iconic speaker systems as part of our collective audio history too. ;-)

    I checked the ad this morning. It has disappeared. Most likely already sold or reserved.
