Default Can You Identify This 18in Woofer? {Photos}

I desperately need your help with identifying this 18" woofer. I just picked it up extremely cheap ---{because the dustcap is pushed in}--- and would like to possibly use it to make a subwoofer. I purchased it because to me it looks like Focal/JM Labs Audiom woofer. Am I correct? If not what is it and are the TS specs available anywhere?

TIA

Oooh, I like the motor on that. Looks like a PA driver to me. Not meant for infrasonic but gives your chest a heck of a thump. Probably good down to about 30 Hz or so.

Looks like MCM's clone of some of the high end Focals.

Yes I thought the magnet structure looked like a Focal. I also like the accordian surround better than the rubber used by Focal "if" it is an MCM clone.

Because of their god awful site, I haven't checked out MCMs offerings for a number of years, but I seem to recall seeing those 4-5 years ago and I was intrigued by them.

Default 22 NOT 18 Inches ((See Photo))

When I brought these woofers home I measured them because my 18" Hartley subwoofers looked so much smaller in comparison. These woofers are actually 22 inches across! Check the photo of the 18" Hartley next to the 22" Focal Clone.

Wow!  Does anybody know anything about this driver?  Is it still available?  Are there params available for it?

I agree about the MCM site.  I make websites for people, and that is my example of an impenetrably byzantine site.  You ain't got the print catalog in your hand with part numbers, it can take you hours to find what you want.

I'm glad to see they're still in busines, mind.  They used to be a cool source of some of the most outa-de-way speakers and other parts this side of Fair Radio Sales.

Aloha,

Poinz

Default More Info!

Hello Poindexter!

Here's what I do know about them so far. They were made by MCM for a limited period of time. It was originally listed as part # 55-1835 in the MCM catalog. It was described as a 21" pro. low frequency woofer and had these specs; 8 ohms, 96 dB @ 1w/1m with a 25Hz resonance. It's rated @ 200 watts rms/800 watts peak and sold for a very reasonable price of only $395!

I'd greatly appreciate any help I could get in locating a second driver so I could build a copy of Nelson Pass' El-Pipo Subwoofer.

Might ask Mr.Pass nicely...as I recall he used four of these drivers in El-pipo
