JBL Performance Series

[Titanium Dome]

Here's a shot of the TM025, 904Ti, 906Ti, and 908Ti, appearing to glow with musical fire within their Ti diaphragms. I was trying to make a new avatar.

After some comprehensive searching, I managed to dig into the Archives Audax or LISTE DES DOCUMENTS AUDAX DISPONIBLES to find an entire family of TM025 dome tweeters. There are both textile versions and Ti versions. Applications and housings are varied and include complete units with flanges for mounting direct on the baffle, adapters for using in horns, autosound mountings, elongated adapters, round adapters, and "snap in" models. Both textile domes and Ti domes come in 8 Ohm and 4 Ohm versions.

After some comparisons to the very limited info supplied by JBL and an examination of one of the Performance Series tweeters, sans EOS Waveguide and black plastic adapter, it appears the Performance Series uses the TM025C3 "snap in" model, thought it's not really snapped in as much as molded or glued into the unique adapter that attaches it into the EOS Waveguide. There may be other differences since it was a custom application.

Here's the first snapshot of the technical data.

Here then is part two:

Lastly, here's part three:

Here's a shot of the rear of the unit, minus the EOS Waveguide and the black plastic adapter. Compare it to the drawing on the tech sheet (first part above). I turned so that it would have the same orientation as in the front/rear drawing. Of course, the upside down JBL parts sticker obscures any Audax markings underneath.

Here's a closer look at the tech sheet drawing for a closer comparison. The small notch at the bottom is not visible in my photo due to the shadow cast by the housing. When I applied a mask to extract the driver from the background, the shadow came with it.

I wonder why all the different curves previously posted have the JBL version dropping ~5 dB above 15K? Maybe the Audax info is from an updated version... :dont-know

If the JBL curves were done installed in the cabinet with the EOS Waveguide and the little "cap" over the driver, that might explain it. :dont-know

The Audax sheet says Nov '98.

I am moving and have decided to sell this whole system. It is still under manufacturer's warranty. I am asking $7000 OBO. I have significant feedback on both ebay and Audioogon, and would be willing to conduct the transaction through those websites if needed. The setup includes:

- 4 X PT800 performance series bookshelf speakers
- 2 X Matching subwoofers
- 1 X Center Channel
- 1 X JBL AV1B Surround Processor
- 1 X JBL AVA7 7 channel amplifier.

Everything works perfectly. Thank you.

Hey zakhaku, you should post this in the forum "Lansing Product Marketplace" for maximum exposure.

Are the subs the PS1400 or the HTPS400 models?

This setup doesn't look very good (yet), but it sounds fantastic. It's just set up this way for testing. I'm happy to be a new member of the inverted Ti Dome club.

Is that one of those Fosgate Audionics subs with an LE14H-1 in it?

If so, it probably mates up quite nicely.

[Don C]

Yes, that's exactly what it is.
