I tried four of these in a parallel qw resonator (240/80 cm lengths, like a folded bose wave cannon). it’s impressive, in a small space, what those 4 little drivers will do, but it’s not a very legit ‘subwoofer’.
I don’t know what else we could do with little drivers?

Good point. Seems excessive. When i did the Met for the FF85wk it was 18” long and an ML-Voigt needs to be longer than a non-tapered (narrow to wide) line.
BTW, i have a pair of those woofers. Not really impressed.

I bet the performance would be alot different in a vehicle, which is what Hexibase does with his enclosures.
Given the room gain in a vehicle very nmuch so.
But thisparticuaor woofer would not be my first choice unless space was extremely limited. The sonics are suspect.
The midTweeter in FH-Lite of Girrafe does better bass than the tiny TB in a reflex. FHL goes lower and sounds better.

try those drivers, they’re only $15 . I bought like 20 of them and put them in TL,’ Paraflex’, TH, br, etc.. easiest way to learn a little about ‘everything‘ (and then realize im even dumber than i thought 😝)
I used a pair of the 1876S in an opposed PR loaded bandpass. I ran them in series for an 8 ohm load. The little chip amp had a 150Hz LP xover, and i wanted it lower. I used an acoustic rolloff to get it. The drivers would not unload at the 15-30W intended, and would fill a room with bass. This is a sub the size of a loaf of bread, and was quite impressive. I call it Goosebump. Bottom end is likely 40-45Hz in room, but that would be at best.
I only build for purpose...new vehicle, blown driver, or paid request.
I have a bunch raw drivers in my stash...3.5", 4" (I think), 5.25", 8", 12", and 15".
These might be the 4".
