Whats the best cabinet for these drivers? I have not been here for awhile and I have a pair looking for a new home. Just wondering if any new designs have come up. Anyone have a preference? I know this is subjective but I am looking for ideas..
Thanks

There is no best, it depends on what you want them to do. Have you looked thru the cabinet plans on the MA website? https://www.markaudio.com/online_shop/alpair/alpair-7-ms/

'Best' is a function of the needs of the app, so ideally need to know your performance goals, room layout/furnishings, in room driver, speaker/listening position details, available power, what, if any EQ available, any WAF considerations; otherwise I'd just give you a T/S max flat vented alignment and move on to the next 'customer' 😉.
I built the Fenlon 70MS box and it sounded pretty good to me! Not a huge size either, which was nice. Was able to get a decent low end out of it too.
I took a look at the Fonken designs and noticed that a few of the larger designs have multiple rectangular vents. Newbie question: what is the rationale behind having multiple vents in an enclosure?
My miniOnkens, the primary ones, were inspired by the side vents in an Onken i saw in a late 1970s in an Audax design booklet.
But they do not use the official Onke alignment.
The vents are purposely long and narrow contirbuting R to the vents and pushing the box from pure reflex towards a more aperiodic alignment.
This typically yields smaller than typical enclosures, they only go as low as they go, bass is elegant and articulate. Partly due to a greater tolerance for dynamic changes in T/S parameters.

If I can ask, Dave, those boxes are tuned to specific frequency. Since they are part of payed drawings, is there data of tuning in drawings?
I don’t really care about the tuning frequency, only the shape of the simulated curve.
Also, the sims do not acount for the extra vent resistance so there is an extrapolation i have to make to estimate extension.
Likely higher than you would guess.

Curious, since I don't know much about horn designs, but are there any compact boxes similar in dimension to the ones above, that use a front horn design?
I see that there are the frugal-horn that have backward facing horns and are quite tall.

Horns aren’t horns if they are too small. A front mouth next to the floor needs to be ≈4x as large as one firung into a corner to have the same LF cutout.
So a front firing horn needs to be larger,

It's really good with 7MS.
