    I see....
    So upon further inspection of Saeman's pictures...they seem to have a 3/4" Birch baffle & 1" PB sides/back.
    In 2008/9...is MDF better than PB for this purpose or is there some other reason to use a particle board?
    Thanks for the info.

    JBL used to use particle board, but by the 80's like most everyone else they switched to MDF.

    It would seem that based on this secondhand account of a study comparing cabinet materials, it would make sense to use MDF for the main cabinet and use plywood for the dog house.

    My 4345 clones

    Here are some pictures of 4345 clones I just completed last weekend. It was a really awesome project and I want to truly thank everyone who posted plans, schematics, and advice on this forum!

    Is that a sheet of glass on top? Are you running one amp, or bi-amping them?

    Hi, I modified the design of the case a bit to include a recessed area on the top for a sheet of glass. Basically they are exactly the same as some L65 Jubals that I own. Figured there was about a 100% chance of my wife setting plants on the top of them so glass was the best option. Unlike the Jubals it is veneered underneath, not black so I used clear glass rather than smoked glass. I built the charge coupled crossover as detailed in plans listed on this forum. But I added the 6 pole switch like the factory original so they could be switched from bi-amp to single amp. Currently I am powering them with a single amp. Picture of crossover attached.
