    Appreciate the efforts with WinISD, but I'm not looking to re-design a cabinet, just plan to use the existing dimensions for the larger C51/61 that JBL already used for this system when they were...

    Well, I've been playing with WinISD without much gain. AFAICT the C56 speakers I have now should have ridiculously long ports or crazy response curves. I don't think it's going to be much help at...

    You reminded me that I already have WinISD on this computer. It's an old version though, beta it says. I'll try putting the C56 and C61 dimentions in and see what it says.

    'Re-cabineting' C56 Dorians w/S1 system

    Got this pair of C56 Dorians a few years ago. They have the S1 system - LE14/LE175/LX10. Replaced the surrounds and the paper caps in the crossover. They sound wonderful!

    The cabinets, however,...

    Well, they're done! Right now I'm just waiting for the second dust cap to dry before testing. I was shooting for getting at least one done and re-installed last week before we left for the weekend. ...

    Well, I don't see any reason to change them out then.

    I still wonder why they made the change... or if there are earlier drawings that spec 4 ohm resistors?

    :dont-know:



    Maybe I didn't explain clearly. It's the drawing of the schematic that specifies it as 5.1. Both of the xovers currently have the same 4ohm resistor installed, so they are...

    LX10 resistor question

    I just finished replacing the 12uf caps in a pair of LX10 crossovers. In the process I noticed that the value of R1 as installed is 4 ohms. Looking at the schematic of the LX10, the indicated...

    The frame is 12 1/8" and the cone is 11", which matches up with Rick's surrounds and the surround dimension in another post. I don't think there's any need to cut them, although the thought did...

    Yes, those are the same dimensions. I checked a third supplier who doesn't think his would be any different from Rick's. I doubt that there's anything wrong with the one's Rick sold me. That they...

    That was my original plan and I think I should have just gone with it now as it would have looked better. After playing with these things for over a week I find myself in agreement with all that...

    Got a reply from Rick Cobb... he's never had or heard of a problem like this. He'll take them back, but then what do I do? Re-coning is out of the question for me, cost-wise. I've got to figure a...

    I managed to get most of the old stuff off. One speaker seemed to be much more sensitive to MEK loosening the Aquaplas, so on that one I ended up "fileting" it off without the MEK. They both came...

    So the goal is to get the old foam to release from the glue, leaving the glue on the cone? I tried a little MEK on pieces of the old surround roll... it does seem to make it much more pliable,...

    Yes, that was one of the threads I'd looked at. They look like new.

    My surrounds are slightly over size in OD for the frame and I don't think the ID will cover the area where the old glue was on...

    With a normal cone and surround, I'd agree with you. But these are a whole different animal. The old surround doesn't fall apart, it gets hard, and the glue is brown on a white cone. The white...

    LE14a refoam question

    I've read through quite a few threads here about refoaming these LE14a's. Didn't seem to find anything definitive as to whether the surround should go on the front or back of the cone. Seems like...
