Diaphragm for Old Version 4"x10" Midrange Horn or Similar Heppner/Foster-type Drivers
Diaphragm for Old Version 4"x10" Midrange Horn or Similar Heppner/Foster-type Drivers is rated 4.5333 out of 5 by 15.
Rated 5 out of 5 by from It worked !Took a look at these and without even measuring the old one I knew this is what I needed. I bought a pair of Kenwood MV-9D (big brother of the MV-7) and both mid horns were blown. These are Military version for sale only in Germany speakers. Very rare almost unobtainium Speakers with almost unobtanium parts. Parts Express came thru. These must be Foster Mids that Kenwood used. If you buy have a small jewelers file ready if using in the same speaker that I have anyway. They will need a bit of trimming to fit.

Rated 5 out of 5 by from What a surpriseWhen I blew a horn in an old 80's Traynor PA cabinet, I fully expected to have to purchase a new driver, since the possibility of finding a replacement diaphragm seem so remote. Apparently these old Foster/Fostex drivers are all over and these babies drop right in and sound great!

Rated 5 out of 5 by from Inexpensive, sounds just fine, about 1/10th the cost of a shop.I picked up a pair of these to fix a blown diaphragm in (and have a back up for) a 25+ year old Harbinger 324 floor monitor.It's just a titch large for the alignment pins, but did snap in place by using a little more force than I'd like. The voice coil does align just fine, and it sounds right in the ballpark with the old driver.Took about 5-10 minutes to install, and much cheaper than the $50-75 it would have cost to bring the monitor into a shop.

Rated 5 out of 5 by from Versitile tweeter diaphramGreat little diaphram. I keep several around because they fit several different types, some need very little modification.

What is the difference between this diaphragm and the Selenium RPDT150?

Asked by: RW1683
While these look similar, the tolerances and overall dimensions will be slightly different since they are designed for two different drivers.

Is the "voice coil flange" measurement overall diameter or voice coil diameter?

I am looking to replace diaphragms with 1" voice coil diameter, and I have seen other replacements differentiate between "voice coil" and "diameter" measurements, e.g. 1" voice coil, 1 3/4" diameter. Just need a little clarification. Thanks!
Asked by: Joseph D.
The voice coil diameter on this diaphragm is 1", overall flange diameter is roughly 1-3/4".

Is this a replacement for the Foster/Fostex type diaphragm?

Asked by: Dutch
I have heard of customers using this diaphragm with Foster/Fostex drivers, but I have not verified this to be true.
