12-inch car subwoofer with exposed copper voice coil and triple-roll surround

B&C

B&C 12CL76 12-inch car subwoofer

SKU CH-BC6F-209Z1

A 12-inch car subwoofer handling 700 W continuous power with an 8-ohm neodymium motor, 98.5 dB sensitivity and a 45-3000 Hz response, optimised for a 40-litre enclosure tuned to 60 Hz

  • High sensitivity of 98.5 dB delivers loud output with modest amplifier power
  • 700 W continuous power handling supports demanding bass passages without compression
  • 45 Hz low-frequency response reaches deep bass notes for full-range impact
  • 76 mm copper voice coil on glass-fibre former handles heat for sustained performance
  • Neodymium inside-slug magnet with 1.05 T flux density provides strong motor force in a compact motor

12-inch car subwoofer with 8-ohm impedance

The B&C 12CL76 is a 12-inch woofer built for car-audio systems that require an 8-ohm load. Its neodymium inside-slug magnet keeps the motor light while delivering 700 watts continuous power handling and 98.5 dB sensitivity. The copper voice coil rides on a glass-fibre former for thermal stability.

Upgrade from lower-sensitivity

This unit replaces drivers that cannot handle 700 watts continuous power or that present a 4-ohm load your amplifier cannot support. The jump is worth it when you need the 98.5 dB sensitivity to reach target output with less amplifier gain and when the 45–3000 Hz range covers your intended bandpass.

Fits sealed or vented enclosures around 40 litres

The woofer works in a recommended 40-litre enclosure tuned to 60 Hz, freeing you from oversized box designs. Its straight-pole motor with 1.05 T flux density and 11 mm gap depth allows a 17 mm winding depth for linear excursion. The triple-roll surround and exponential cone shape maintain control at high displacement.

Questions about this item

What enclosure volume and tuning frequency does the 12-inch B&C 12CL76 need?

The manufacturer recommends a 40.0 litre (1.41 cubic foot) enclosure tuned to 60 Hz for this 12-inch woofer.

How do I wire the 8-ohm voice coil and what clearance does the 76 mm diameter require?

Present an 8-ohm load to the amplifier; the 76 mm (3.0 in) voice coil needs a magnetic gap depth of 11.0 mm (0.43 in) so ensure the pole piece and front plate match that spacing.

When should I replace the spider or surround on this subwoofer?

Inspect the single spider and triple-roll surround for cracks or loss of compliance after heavy use; replace them if cone travel becomes non-linear or distortion rises.
