I'm putting together a 'speaker kit' as a graduation gift to a nephew. Kit in the sense that I'll cut out the pieces and do the holes, etc. as well as provide all the parts. He can glue it together. Looking at an 11MS, and the Nostromo and MarKen configurations are both attractive. Is there a specific MarKen configuration for this driver. I would prefer to use 18mm baltic burch, but can upscale from 12mm using internal dimensions. I'm happy to pay for plans or donate whichever way I go.
Yes, A11ms Mar-Kens include trapezoid and retangular full-on miniOnkens and a CGR.
Note: the full-on miniOnkens flat-paks are tricky. Given the dry fitting need almost as easy to just do an assembled one, but that would remove one step of fun for your neph (non-sexist term for offspring of your siblings).

Exactly what I'm looking for! Where do I access the purchase interface? ThanksA CGR might suit your needs.

Is it PVC or PVA? I'll look for "This stuff is a PVA compound very similar to white wood glue" but I would be very tentative about applying it to expensive drivers like the MAOP7.
For the record since I would have to design a 2-way crossover for the SEAS woofer and MAOP7, where would one find FRD and ZMA curves for these drivers?
Thanks, Scott. I would be using 4 woofers in about 42-43 litres. At least that's the plan.
The next challenge is to find the FRD and ZMA data for the Mark Audio and SEAS drivers.
Well, you get those by measuring the in-box impedance and frequency responses with relevant equipment (I generally use Omnimic and DATS, though I also have Holmimpulse and ARTA available as-needed). REW is popular (and free), and you can make suitable jigs for impedance measurements quickly & inexpensively; if I'm going down the USB route though, the aforementioned, while requiring more outlay, I find work better for me. Personal taste.
They aren't available online? I was hoping they would be. The data to some (I presume) older drivers is available here: https://www.rjbaudio.com/Audiofiles/Driver FRD files.html
No idea on that one, I can't know everything everybody else does or is up to. 
You can trace manufacturer responses & post-process them in relevant software for baffle effects etc. However, the accuracy of this is at the mercy both of the manufacturer data and how much of that there is, and also how well you do the post-processing job. To give one example, in this case, you've got drivers that will be 90 degrees off-axis (unless something has changed). Seas don't have that data, so even with a relatively low XO you're in the realms of guesswork to a relatively significant degree when modifying the available information -rarely a good plan unless you're prepared to do a fair amount of experimenting, preferably with measurements, as they will allow you to identify issues & get the balance right a whole lot faster.

You are right! With my woofers being 90 deg off-axis of the MAOP7, I doubt anyone will post data of the SEAS woofer's 90-degree off-axis response.No idea on that one, I can't know everything everybody else does or is up to.
For on-axis response, the method used here might be useful.

Sorry, typo. PVA.
You do not want to use it on the MAOP. It was suggestted to helpout the wild ringing in the Al woofers. Even if you have electriclly suppressed the resonance, i still think som edirect fix so it does not need to be as harsh.
