wonder how this would do as a noisemaker ?

double PA310 "XKi" in a Karlsonator 12 sized box

dunno how close a BP sim comes

almost bet there's some high velocity wind from the upper area of the slot

box volumes in sketch are for Kappa12a

sim is 2pi 33V

Looks like it will work as a kick bin. It'll DEFINITELY do sub duty in a vehicle tho'!

Yep, looks like plenty of "kick". Not sure about subwoofer duties, though - unloading below Fc will be a problem, no matter the environment.

Transfer function is amazing in vehicles.

I actually used a PA310-based box in a car a few times (my POC3 build). That's a 40 Hz design though. Yeah, it does well, considering I paid around $60 for the driver. Big box for a 12" driver though.

Yeah, for mobile audio, a Pi Align is probably a good trade-off between size/extended bass gain BW.

Too bad you didn't take an in car measurement to show transfer function. Still a CLASSIC build tho'!
