I have a fairly large selection of AR tweeters and midranges that I've decided to sell. Below is a list of what I have with links to photos below the description. Many of these are AR reference drivers. This means they were the actual original driver that AR used to design the speaker product around. I have tested all of these drivers. They all function correctly, unless noted. If you are interested in any of the drivers, please contact me at jhidley at comcast dot net.

2-11-005-1, 1.5" midrange used in AR 338 and 338T speakers. Excellent condition. One of these drivers is the original reference driver. Three drivers are available.

10pi 1.5" beebut style reference midrange. Made is USA. I believe that it is the same as the LST and 3A also, if the cabinets are converted to rear mount leads. At some point in this drivers life, the screen was crushed. I've pulled it out of the dome, but the impedance curve is still rough around 500-1,000Hz indicating that the dome is touching the fiberglass underneath. If someone cuts off the screen, pulls the fiberglass off and reglues it, I'm sure the driver will work perfectly. One driver is available.

2-11-002-1, 1.5" beebut style midrange from the 302, 302T, 303, 303A. Two drivers are available. One of them is the reference driver. Can you guess which one?

1210010-1, 1.5" beebut style midrange, made by Foster. I believe that this fits the 10pi, LST, 3A, etc. One driver is available.

200048-0, dual dome midrange/tweeter module. Made in USA. This fits the MGC-1, 9Ls, 9Lsi, 98Lsi, 78Ls. These modules have lots of dust on them. I have made no attempt to clean them. Three of the four available are reference units.

1-210064-0, 1" soft domes, made by Foster. These were used in the MGC-1 as the side firing tweeters. I'm not sure what else they fit. One of them has an AR logoed faceplate. The other two have the generic Foster faceplate with exactly the same dimensions.

205VC 1" soft dome center channel reference tweeter. I can't remember what the part number for this is right now. One driver available.

2-11-008-1, 208V center channel reference tweeter. One driver available.

2-11-003-1, 338, 338T, 302, 302T, 303, 303A 3/4" soft dome tweeter. One of these is the reference driver. One has something spilled all over the faceplate. I'm sure I can clean this off. Three drivers are available.

2-11-007-1, 218V 3/4" soft dome tweeter, shielded. This is the reference driver. The dome has been crushed, but the driver measures fine. I'm sure that I can repair this with a little work.

I also have four reference woofers for the 302 and 302T. I believe that the part number is 2-11-010-1. Perfect condition.

jack,
have just posted for advice on AR7 restoration.. I've become a member so as to seek this advice all the way from Belgium.

The 7's were free from my dad, who got them from new. inside as new and sound lovely.

Q. the front cloth needs replacing. how? the back looks like a complete No No. and before I just hack off the fron cloth...advice would be great. don't want to be left with naked speakers and no idea on how to re-cloth them.

any advice greatly appreciated.
