    Gee, the only Mandingo I'm aware of is a big 12 inch.

    I recall Kevin Haskins working on his 21” prototype.... I don’t believe he got beyond that point. Business decisions. ROI VS just giggles and grins —-EGO. obviously, he was content with the anarchy drivers he had.

    If I had a big room I'd go stereo 21's. But I don't, so I won't. One 18 will just have to do. And very nicely too!

    Do you have an attic? A couple of those new Eminence 21's in a ceiling IB would rock your world.

    Here's a shot of Dayton's new 21-incher in 12 cu ft vented enclosure tuned to 24Hz. (Not my build, by the way.)

    My IB is two 15's from PE in a manifold through to my garage. Works very well.

    My last house had two aurasound 18” drivers as an IB. I’ve usually liked their drivers. I built the north speaker Leviathans, nice BIG sub. My present full range speakers have a single 10”Aurasound per/side. Anarchy had an 18” for a awhile. Wish I bought a few. I’ve used their 12 (shiva) and 15” tempest variations. Still have two tumult’s in sealed enclosures. With Dan Wiggins big boy plate amps.
    Giggles and grins it might be nice to experience a 21” driver. Back in the day wasn’t there a macCauley 21” driver. My mind is gone fuzzy.

    So, this new 21" (346.4" sq) has got more surface area than my 18" (254.5" sq) but the xmax is half of that of the 18". Also the 21" falls 15 dB from 100 Hz to 20 Hz while the 18" only falls 5 dB over the same range.
    So how does that boil down in terms of output for a "Sub-Woofer"?

    That's where enclosure design comes in. You'd have to model each in the intended enclosure to find out what the performance will be (or better yet build them and measure.)
