IMO, even if the EL166 was workable in the 800-2400 range, it wouldn't have the "magic" of the 3" Fostex
yup to the first - as to the second, based on listening to 3 of the new WK's (only full range so far), I'd say possibly a few Hz. Not the least of the advantages of the new series is smaller minimum enclosure volume for same LF performance (for example, I've got a pair of boxes underway for the 125WK that come in at 9 liters, vs approx 13 for the same style enclosure for FE127E)
I am going to move forward with the single woofer version. This is my first build and I am very excited.
I am going to change the cross-section so that inside dimensions are about 11.5" x 5.2" and use a single fold to make a large bookshelf out of these. Should I need any bafflestep correction with a 12" wide by 18" tall baffle and a 1st order XO between 300-400Hz?
More or less... I got all the white ones (+ a pair of black), and Toppsy got all the rest.
I have a few spare to my needs, i'd like to sell them treated but might let some out stock.
Talk is that interest has grown sufficient as it neared running out that Mark is working towards another batch... fingers crossed, it is one hell of a mid-woofer even discounting the cheap price.

Ah, okay. I had been eyeing it with some future plans in mind. I was really impressed with the ML-TL I heard last summer. I have been obsessed with the idea of building some round tractrix horns for a pair of inexpensive compression drivers and it might have made a suitable lower end. Utterly pie-in-the-sky though. Unclear on WAF, utterly beyond my current skill set (horn design), too large for any room in my house. In other words: perfect! ;-)

I just about managed to get a pair of black ones before Colin cleaned 'em up.
Still lagging behind on my EL166-MLTL build...
Dave, if woofers are push-push, does the cabinet need holey braces?

I designed a pair of speakers (Edingdales) using 4 x Woofer#6 (EL166) in a line array type arrangement coupled with a ribbon tweeter. The woofers are wired series/parrallel to maintain a nominal 8-ohm load and so are a in essence a simple 2-way speakers Xing over to the ribbon at 3.5kHz. The idea being to make them an easy load with sufficient efficiency to marry to a pair of 300b Monobloc amps.
These have proved to be a real winner such that I started a search for as many the remaining available stock left that I could buy up. These speakers have been pitted against a £3000 pair of commercial Yamaha speakers and a a pair of £7000 Living Voice speakers. Both owners of the commercial speakers have placed orders for me to build them some Edingdales to replace their (previous) cherrished commercial speakers. The MA mid woofers are that good with a midrange that rivals my Quad63 electrostatic speakers.

KyleinCowichan,
I don't think there is consensus of opinion on this. I crossed over to my Ribbons at 3.5kHz as that was the lowest usable frequency of the ribbons which are 98dB efficiency and at that point on the woofer FR plots there is still no apparent sign of cone break up. Looking at the woofer FR plot I wouldn't want to XO any higher than 4kHz.

Hmmm...looks like others also realized this at the fag end of the driver's run in retail.
Colin, any luck with BPA? They had some white cones for their kits if I remember correctly.
Where other Mark Fenlon drivers like the Alpairs stand out in their appearance, the MA Woof #6 aka EL166 is pretty unassuming. Seriously need to get my ones in a cab.
Coiln, do you break in the Woof #6s or it's heavy duty from the start?

Hi Zia,
BPA have only stock to sell with their speaker kits. They won't sell the drivers on there own. Or that was my experience last I tried to just buy drivers.
I don't break in the W#6 (EL166) drivers, they sound good from the off. Unlike the Alpairs these midwoofer cones are quite robust so just install them in your finished cabs and play music. The midrange richness will get better after around 50 hours use. I also suspect the break in of the XO components helps here also. Using the 4-drivers wired series/parrallel, each driver is doing a quarter the work of a single unit but combined give you the area of a 12" woofer! This has the effect of reducing the distortion by a good factor of 4 which manifests into the wonderful rich and detailed midrange. Also even played loud the cones hardly move but produce real deep and detailed bass.
