Here are a couple of pictures from a 2414H pair I got from ebay.

It is used in some new models like the AC16, and also replaces the 2408H in some models (for example in the PRX535, since 23/06/2008)

Is is quite, small, even when compared to a 2407H as you can see on the photo.

The 2414H-1 use in the new eon serie is said to be even smaller, and according to Zilch "has the tiniest neo magnet I have ever seen in a driver".

disasembled!

Unlike the 2407 and 2408 it is not a ring radiator but a mylar dome.
It has ferrofluid in its gap.

Now some measurements!

Measured with smaart live on a PT-D95HF-1 waveguide (AC16), mic ~1 ft away.
15uF protection cap, active butterworth HP filter at 674Hz, 24dB/oct.

Caveat: the drivers come from ebay, so they might be out of spec.
Both drivers measured similar (albeit not perfectly matched).

now the exact same measurement with a 2407H (also from ebay)

Clone the AC16 filter, post the result, and I'll post what I got doing that.... :yes:

I found a photo on ebay. Tiny indeed!
The other side is similar to the 2414H

Sorry to bump this old thread, but I came across it and eventually wanted to correct a misspell:
The horn used was the PT-B99HF-1 (6" square from the AC16, 90x90), not the PT-D95HF-1 (8" square from the AC18/95, 90x50) as written in the pictures above...

By the way, does anyone know if the PT-D126HF-1 (#365124-001) is still available trough parts?
I wonder if some cheap 6" or 8" M2-derived waveguide will appear in the compact installation speakers...
The PT-D126HF-1 looks nice in the AC18/26 specsheet (http://www.jblpro.com/BackOffice/ProductAttachments/JBL_AC18_26.v1.pdf), but I would prefer a larger vertical dispersion, and the horizontals also tend to beam a little above 8kHz...

It looks like there is a ferrite version of the 2414H, probably because of the price increase on Nd :

2414H-C, not so tiny now...
