    I thought about it for a while, and they are not for me. For the cost of one diaphragm I could buy a pretty good pair of speakers.

    TAD TD-4002 Throat Adaptors

    Are the throat adaptors on a TD-4002 specific to a TAD, or do they fit from other drivers? I can't even find the dimensions of the driver without the adaptors, I just found a low resolution picture.

    Yes, I made a pair of Hartsfields a few years ago. If you are thinking of doing it, I wouldn't recommend it, way too much work.

    Ive never heard a pair of 4345s with stock drivers, so I can't compare. I had a pair of homemade speakers that had the same drivers as these except the low end was 2 2226 15" woofers. These sound a...

    In this picture you can see the mounting holes and the top of the cabinet. It's difficult to start the screws on the frame when when the speaker is standing up, maybe that's why they use the MA15...

    I doubled up the clamps because that was the way JBL did it. I am using screws in the eight holes also, you probably can't see them because they are silver. This is an 18" 2245 and the enclosure is a...

    Since everyone else was building these, I figured I had to also. The cabinets are almost an exact copy except they are baltic birch, teak veneer and the port outlets are flared. I made a little...

    It fits a L250TI, so at least it for a popular speaker that I will never own. I probably will never own a 076 either, but there is a lot better chance that I will.

    I have $75.00 in to it, so I...

    I know I bought some on eBay from China a few years ago, the shipping was reasonable. I can only find USA sellers now that charge more for shipping than the clamps cost.
