The story behind the speaker:
About 8 years ago this was designed as an active Pro monitor system, the M60. The electronics contained DSP hardware from DEQX, Australia. The woofer is essentially a SEAS W17E-002 however we found that when used in a sealed box, you can hear air chuffing out around the phase plug so we had SEAS remove the phase plug and install a dust cap. The magnet also has a shielding bucket. The cabinets are thick MDF with an internal brace and finished in matte black. We sold all the active electronics, and somehow we ran out of tweeters before we ran out of woofers and cabinets.

So here’s the deal: we have 10 pair of these NOS speakers wired up but without tweeters. All they need is a tweeter and a crossover. Total cost is only $275 per pair, shipping included. One woofer alone costs $233.10 at Madisound. FYI, the original tweeter was a SEAS 27xxx aluminum dome with a 103.8mm diameter faceplate. There are several SEAS tweeters that will fit.

Or we have 20 woofers for $100 each, shipping included

As an example I made a passive crossover using the original tweeter. Here are the results:

The crossover has 7 parts total (or 6 if you can find a 0.2mH inductor with 1 ohm of DCR). It is possible you could use the woofer section and just modify the tweeter part to match a different tweeter, with minor changes.

Hi
Seas W18E001 comes with magnesium (different color) come, these look like has aluminium cone based on the color.
Are you sure these is Seas W18E001
The reason I ask because long time I`m interested on that driver..
Would be nice a picture where we would be able to read the stickers on the driver.

Greetings

The front of the excel drivers can actually be coloured any colour in the surface finishing. I've seen black before too. Besides on the magnet sticker you can see it says W18E.

Thanks
I just wanted to be sure these is SEAS Excel and not other Seas driver
The other think one must know the model to design a decent crossover (and enclosure) even if he likes the driver.:)

Thank you

The part number on the driver is: W 18E/TV-NHT, H 1387-08 ohm
But you can't look it up anywhere because it is a custom part# for NHT.
As I said it is essentially a W18E001 with the phase plug removed and a shielding can added. If you want I can measure the TS parameters and post them. They probably won't exactly match the W18E001 data sheet because TS parameters vary quite a bit depending on drive level, temperature, VAS calculation method, etc. I even have response curves, impedance plots and LspCAD(V5) design files for the crossover if anyone is interested.
