    Never heard of a 2243HPL. I guess it doesn't matter as "perfect condition other than the voice coil being open circuit" means it is a raw empty frame you are buying. I love these eBay descriptions!

    It looks like a 2242 frame to me. I was going to suggest you ask the seller to take some measurements of the basket depth etc. I see you bought it. When you get the frame measure it and post. I am sure someone with a handy 2242 can measure theirs to confirm.

    The 2242 recone kit is quite reasonable at $169.

    Looks like `42

    But in the pics, it does seem to say 43!

    Never saw this before. maybe they have a different designation for the UK?

    tis indeed 2243

    im in contact with jbl to find out the theile/small parameters

    this is their initial response (nb the parameters aren't in the link supplied).....

    "Dear Sir,

    The 2243 T/S information can be found on our website www.jblpro.com
    This link takes you directly to the page you need: http://www.jblpro.com/pub/technote/thiele.pdf

    The 2241 is a different driver design and the cones are not interchangeable. The recone you require is a C8R2243 and this should be available via one of the service outlets of Harman Pro UK. Max Lindsay-Johnson (head of division) or Tom Williams (acoustician/technical support) who are cc'd on this email will be able to help you here.

    Thankyou for your enquiry, Best Regards,
    Mark Bailey
    JBL Professional (Europe)"

    i'll post the details when i find out

    cheers

    C8R2243 is a foam edged cone.

    Sorta like a 2241 and a 2245 crashed into each other.

    Closer to a 2241 which means a 2242 kit will not fit.

    This speaker was used in the Synthesis in 1998.

    All above info was provided from our friends at JBL Pro

    Its a weirdo!

    hi oldmics

    do you have any info about the parameters of this driver?

    is the 2243 foam edge cone my only option to re-cone this driver?

    Sorry no other info.

    If I were in your shoes,I would take the frame to a service center and see if a 2241 kit fits into the motor assembly.

    Of course the correct way is to use the C8R2243 cone kit and restore it to original specs.
