    I'd buy a couple of these networks myself if they were in stock but they aren't. MSRP on them is around $135 each. The 1400 Array networks (HF/UHF) are roughly half that price and out of stock as well.

    The coil values and their DCR's have to be measured out of the circuit. Too bad JBL doesn't leave the stickers with that information on them. Those 5W 1ohm8 resistors might be 1.8 ohm instead of 1.0 ohm.

    As soon as I can get a pair set up I will send you my networks to dis-assemble and re-assemble as you see fit.

    I have just upgraded my S&L speakertester to the woofer tester pro, so I am awaiting my license file. I should be up and running no later than Monday or Tuesday

    I just finished hooking up a DBX 223 X-over to a Rotel RB1080 to run the SAM's and my MC602 on the LE14H-1's in Citation 7.4 cabs.

    WOW!! pretty much plug and play!! X-over set at about 750-800hz 24 db per, everything set a 0db.

    These are really smooth and blend with the 14's REALLY well.

    Now lets remember that I have only had Ewaves with the Selenium drivers and LE14's for the bottom so that was my first horn system. They did do the intended purpose , which was to get people interested.

    These are wonderfully smooth and detailed. And now I will give you a pic and then back to listening!!

    It appears that you nailed it.

    Here is what I got by taking one apart:

    R1 20 ohm 10 watt
    R2 20 ohm 10 watt
    R3 12 ohm 25 watt
    R4 13 ohm 25 watt
    R5 1.5 ohm 5 watt
    R6 1.8 ohm 5 watt
    R7 2.4 ohm 5 watt
    R8 0.75 ohm 5 watt
    R9 39 ohm 10 watt
    R10 39 ohm 10 watt
    R11 1.8 ohm 5 watt

    C1 47 uF 100V NPE
    C2 0.01uF 100V MPT
    C3 100 uF 100V NPE
    C4 0.01uF 100V MPT
    C5 6 uF 100V MPT
    C6 12 uF 100V MPT
    C7 5 uF 100V MPT
    C8 2.5 uF 100V PMT
    C9 2.2 uF 100V MPT
    C10 1 uF 100V MPT

    L1 0.5 mH 0.7 ohm DCR AC
    L2 0.1 mH 0.4 ohm DCR AC
    L3 1.9 mH 1.3 ohm DCR AC
    L4 1.2 mH 0.8 ohm DCR AC

    Here is the schematic in LEAP. It has some similarities to the 1400 Array network.

    I don't have any data files for the 435AL or 045TI.

    Those look like Citation 7.4 subs in the photo. If they are you might want to check and see if there is an inductor in line with the LE14H-1's inside the enclosures.

    I just ran a wire through the port at that time, but the inductor is bypassed now!

    Thanks for the work on the XO 4313B!!

    BTW they are also 14-3's now.
