Stereo Integrity TM65

From their Facebook page:

We will be coming out with a shallow 6.5" mid/woofer in the next couple months. Here are a few pictures of the design process and notes about the design and performance of the woofer.

In the picture with two woofers the first prototype is on the left and the new prototype that will be production is on the right. The first proto had a chrome finish to the motor but production will have a nickel finish due to better adhesion properties between the steel parts while still providing resistance to weather. The production motor has a larger ID yet is slightly shallower to result in a 2.3" mounting depth.

The second picture is of the assembled new prototype that will be production. The third picture is of the voice coil and spider. This woofer will utilize a six layer copper clad aluminum dual 4 Ohm voice coil. It uses a nomex spider with sewn-on flat leads and a shallow profile treated paper cone and dust cap with a compliant (soft) rubber surround. Our 6.5" woofer has an XBL^2 motor allowing for 9mm of Xmax.

This woofer can be mated up to a tweeter as its high frequency extension is up to 2,500 Hz and the woofer is 89 dB efficient.

Complete list of T/S's are:

Re: 6.8 Ohms

Fs: 57 Hz

Qes: 0.44

Qms: 3.70

Qts: 0.39

Le: 1.10 mH

Sd: 13966 mm^2 (21.64 in^2)

Vas: 11.57 L

Mms: 18.1 g

Cms: 417.6

SPL: 88.77 dB (1W/1M) - basically 89 dB as production units may use a little less glue than I did building this one.

SPL: 89.47 dB (2.83v/1M)

Xmax: 9mm

Xmech: 12mm

Price will be $125 each plus shipping.

Here's a link with a video of the old proto:

New video:

Look pretty solid. Seriously considering my spare set of Anarchy's for a pair. Just gonna wait until I see an FR graph, and that should seal the deal.

Are these the same guys responsible for obsidian subs?

sundown, obsidian, stereo integrity, all designed by jacob fuller if im not mistaken

[ZAPCO209]

Thats what i thought, should be a quality mid then.

[TheMonolith2001]

That mid looks awesome and all but after checking out the website I got completely distracted by that 24".

Looks like a great woofer, but I'd really like to see a nicer looking cone. That would look ugly as hell in my kicks.

Had a pair of Exodus Audio drivers like this back in the day. Very nice drivers.
