There is, one is short & one is tall, but -- with appropriate change in cross-section and vents -- you can put one or two drivers in either one.

Well, then i prefer the taller one since it put the EL70 higher up than the shorter one.
Since there is two different ones, is it possible to make a third even taller without changing the sound?

I just came up with an idea. Wouldn't it be possible to tilt them back somewhat to become less off-axis?
Just place some spacers or something underneath the front of the cabinet to tilt them back a little.
I think i may go calculate how much i'd need to tilt them. But not today, been doing enough math for today 😛

Yeah, i bet they will go low enough for me. But i just want the EL70 to be quite on-axis since it sounds better that way than being very off-axis.
What would the sonic differences be between two EL166 and an ERT26 tweeter versus two EL166 and an EL70? Ofcourse crossover is different and the EL70 version is a little more expensive.
Thinking of this as my school project for next year and hoping to get some sort of sponsorship 🙂

A crossover too high for the spacing, drivers near the limits of their passband, XO right where ear/brain most sensitive
vrs
A crossover where driver spacing ~ 1/4 wl, drivers with lots of passband around XO, XO where ear/brain is less sensitive

that give you plenty of time to collect empties from the weekend parties, and wait for the mail
If you wanted to stick with MA drivers, the Alpair 6P would be another candidate - the 6M's can dig deep enough for HT rear/surrounds, and I've heard the 6P solo in a smallish box - I can't see either of them not working well as mid-tweeter. The big question would be choice and method of XO (i.e. frequency point and active/passive), and amplification (which could also be DIY'ed) .
A school project with thorough documentation of the decision making and design process, as well as the construction, could be very impressive to the teachers, and a great shared learning experience. You might even be able to sell a few.
Yeah, i hope it arrives before i leave to Turkey on the 6th of october.
I'll take a look at the alpairs. I guess they sound better than the EL70?

Made pretty and now off to a new home.
Just ordered a case of EL166 to do some more variations.

lucky strike on highly figured book matched Cherry - 2 4x10ft sheets was enough for both the MTMs, the dMarKen7.3T, and wall mounted woofers cabinets for a 5.1 system, with still a few scraps left over
my camera and skills doesn't quite do justice to life and depth of grain with 4 coats of catalyzed lacquer
as answered above - yes cherry but with an almost curly maple figuring on these sheets
Chrisb,
Handsome build (as always)!
Sorry if this has been already covered before - what frequency has the XO point been put? How would this design work with the new XBL tweeters from CSS?

Interesting. Wonder how EL166 tonal charactristics would be over the first 1k. FR chart shows pretty flat even higher.
BTW, the unit in the picture, that has the Fostex FF85 IIRC. New FF85WK can be XOed lower even, or similar?
