Well now that I have a pair of MAOP 11 on order from Madisound. Are there any bookshelf designs around for these or anything loosely compatible, maybe the Nostromo reflex cabinets that were posted for the 11ms?

I had a look at the tuning in WinISD, and it looks like either the small or medium Nostromo box will work fine for the MAOP 11. This is based on the standard QB3 alignment. The medium box will give you a bit deeper mid-bass, especially at around 1.0 ohm series resistance.
What amp would you be using?

Okay thanks. The large Nostromo isn’t compatible? I have two SEP amps and a Nakamichi TA3A that has been upgraded and modified.
I would generally recommend avoiding QB3 alignments in practice unless you have the speakers positioned well out from room boundaries, or are willing to add some acoustic resistance to the vents. That said, this is DIY. 😉
Change of plans. Modified my order so instead of the 11MAOP I'll be getting 2 pair of the 11MS so I can build myself and my father matching sets of speakers. Will document the build and take photos when I get everything started.

Just using it for illustrative purposes.😉

Nice.

MAOP 11 fits into the Plu-Ken for the Pluvia 11, with an increas eof the vent spacer by 3mm to 84mm.

Got my 11ms order in. They’re marked Gen 2. I want aware there as a gem 2 and can’t find anything online about them even on the MarkAudio site. Can someone tell me what the difference is between them?
I replied to this question where you asked it on the other thread; link: https://www.diyaudio.com/forums/full-range/324962-markaudio-drivers-63.html#post6806262
I did see FHXL recommended for the 11 MOAP, but am wondering if 11 MOAP would also work reasonably well in a JOAN Horn?
E.J. Jordan and Mark Fenlon
I remember reading on the E.J. Jordan site, long ago and prior to Ted's work with EAD, an explanation from Ted about ending both his professional and personal relationship with Mark Fenlon. Mark Audio was offering a new driver and called it a "Jordan" driver (I don't remember the model number, but it looked interesting to me), but according to Ted, it was a "cheap driver" designed for an "OE application," and that Mark Fenlon had not contacted Ted about the driver or its design, and Ted said he did not authorize the use of his name on the driver. Ted's statement came across as quite angry; I acknowledge that my American English and culture is different than British English, of course, but I don't think I misread Ted's anger. That direct comment and some other reports I read about Ted, suggested to me the was meticulous, deliberate, and sometimes difficult to work with; if true that would not be an unusual characteristic for a bright, perhaps brilliant, and particular sort of mind. ***I should note that in my limited email correspondence with Ted, when I suggested he has made a couple of errors in converting the US feet to meters in an article, and when I asked for clarification about a claim, he was warm, courteous, and thankful for the correction.
I have also read Mark Fenlon's comments in interviews about his relationship with Ted Jordan, and I found them to be professional, measured, and appeared to be a sincere effort to be fair. Mark essentially said that he appreciated their work together and that he learned a great deal from Ted. Mark added words to the effect that while their relationship wasn't without it's challenges, the main issue was simply that his design philosophy had evolved over time (such as his interest in developing paper cones), but Ted wasn't interested in those changes in either design philosophy or materials. Fair enough, reasonable minds can disagree.
There is a different version of this story from Ted's side. MarkAudio was a contractor and my understanding is that at no point did Ted intend to hand over the business, so the gentleman's understanding may have been miscommunication or misunderstanding. It is, in any case, water long under the bridge.
