Not too many 21's floating around nowadays so I figured I'd make a thread, especially since nobody to the best of my knowledge has used this subwoofer in a car before.. It's a B&C21sw152-4. Very strong neo motor, 6" split wound coil, 15mm of xmax (1way), 30mmxmech (1-way) and aluminum demodulating rings. Plays up to 500hz very cleanly so it could be used as a midbass/lower midrange if you chose to do so (96db/1w/1m). Should be a great SQL woofer in the truest sense of the word. Anyway here are some pics, the pole vent is silly huge.. I can set a coke can in the hole and it fits perfectly.. Plan on using it in a 6th order series tuned bandpass, just need to find a good builder for the design.
8 pro audio midbass on left, AV15h middle, B&C21 right
B&C dustcap same size as 8 (literally)
15 and 21 upside down.
