Woofer: W18E001 (SEAS modified, no phase plug, shielded)
Tweeter: None (103.8mm cutout)
Crossover: None
Cabinet: MDF with 1.5” thick front baffle. No parallel sides. 15” tall x 13” wide x 10” deep
Connector: Dual banana jacks, suitable for bi-wire or bi-amp
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.
If you want more details, send me an email. I’ll get back to you as soon as I can.
