Description
Weight matters when you’re loading a cab in and out of a van at 11pm, and this Celestion BN12-300S proves you don’t have to sacrifice low-end authority to save your back. The neodymium magnet keeps the whole unit down at 4.4lb, yet it’s still rated to handle 300 watts through a 4 ohm load — plenty of headroom for gigging bassists who dig in hard.
The Kevlar-loaded paper cone with a polyimide former and cloth-sealed surround is built to take a beating night after night, tracking your attack from a tight low B up through the growl and grind in the mids without falling apart under pressure. With a frequency range of 50Hz to 4kHz and sensitivity of 99dB, this driver stays responsive and loud without needing a wall of power behind it — a real plus if you’re running a smaller head or splitting wattage across multiple speakers.
Whether you play with fingers, pick, or slap, the 2.5″ copper voice coil and 10.37Tm BI rating give you the control to shape tone rather than fight it. Drop it into a custom cab build or use it as a replacement in an existing enclosure — the mounting geometry is straightforward with a 283mm cut-out and four mounting slots on a 297mm PCD.
