Product Info
* Prices may vary. Check retailer for current pricing and availability.
The B21 is a serious subwoofer, no question. It’s built like a tank with that birch ply housing and that 21” neodymium driver really moves a lot of air. If you're running a large sound reinforcement system for concerts or events where deep, impactful bass is critical, this is a fantastic option, but be prepared for a workout moving it.
