Try a few designs with this and see what you guys come up with? Hes open to trying many things in the name of science🤓👍🏼
(try and get it to stay flat)

It’s actually 21 mm but these SPL drivers with tight suspensions drive me crazy with how they just go nuts at resonances and are lack luster in between??
much like super high Qts drivers, the super small Vas ?
i suppose this is why the skar ddx12 💩 the bed so bad in paraflex and then does so much better in a roar ? Long skinny pipe in the roar damps the thing?
i can’t tell? It’s like the worse possible combo of TS parameters to try and design a descent subwoofer with. Car audio ‘SPL‘ drivers are rediculous

No, just designed for very specific apps; I mean many (most?) of my neighbor's vehicle's (mostly some 'flavor' of truck chassis based) subs are literally 'one note' sealed boom boxes, so judging by the fact that their amps are as big or bigger than their subs, peak power handling is apparently all they care about.
Well hopefully you get to have fun advising/experimenting with these noise makers even if they don’t make actual good speakers….
I think its still fun to exploit resonance and cancelation using subwoofers and horn response like a puzzle to solve/arrange

A default 45 Hz TP 2:1 CR will be flatter than predicted, is only 18+ L net, yet nearly 130 dB/1 kW/~40-150 Hz in a corner from an 8", so somewhat more in a well sealed/constructed vehicle is well above any performance I ever expected to see in my lifetime!
Actually, no, only a few of the same (big) family as all the others prefer to buy the latest 'fad' sub design as a part of 'oneupmanship', so guess because they're mostly construction workers they don't want to spend any quality time (family, parties, mass quantities of food/alcoholic beverages, etc.) doing woodworking other than building/adding on to a deck and/or another 'wing' to their homes for the next party/kid(s).
For sure they work hard and play hard! But most of their music I don't care for and worse! even my well insulated house to keep my 14 Hz in isn't good enough to keep their droning one-note mid bass completely out when cranked up a bit, though if I go out and give them a Caesar's 'thumbs down' they drop it enough without complaint/whatever, so could be worse.
Anyway, the forums are pretty much it, 'bench racing'/'Meets' (DIY) audio has never been very big in metro Hotlanta and even then it was mostly folks from the PE forum where I was quickly, ~politely banned, so stood out like a 'sore thumb' at the few Meets we had way back when now. Early on though, did have a lot fun with the Altec, etc., vintage folks and even some AR1 folks with the 8" Altec 755 wide range 'tweeter'.
