15-inch Neodymium Subwoofer for Car Audio

The B&C 15SW115-8 is a 15 inch car subwoofer built with a neodymium magnet structure. It presents an 8 ohm nominal impedance and a 4.5 inch voice coil. This driver suits enthusiasts adding deep bass to a vehicle system.

Thermal Behaviour and Power Handling

The large 4.5 inch voice coil dissipates heat efficiently during extended playback. Neodymium motor mass keeps the assembly light without sacrificing motor force. The 8 ohm load reduces current draw on the amplifier.

8 Ohm Impedance Defines Amplifier Match

The 8 ohm rating determines which amplifiers can drive this subwoofer cleanly. Builders needing a 4 ohm or dual voice coil option must choose a different model. This single-coil design suits specific wiring topologies only.

Questions about this item

How is the 4.5" coil installed in the 15" subwoofer, and what step is often missed?

The 4.5" voice coil fits into the motor gap of the 15" frame. The step often missed is centring the coil evenly before tightening the spider and surround screws, otherwise the coil rubs the gap under excursion.

What maintenance or replacement will the neo magnet assembly need later?

The neo magnet itself does not degrade, but the 4.5" voice coil and suspension can fatigue after heavy use. Plan to recone the driver when output drops or distortion rises.

What limit shows up first on the 8 ohm 15SW115-8 during sustained high output?

Thermal compression in the 4.5" voice coil appears first. As the coil heats, its resistance rises above 8 ohms, reducing power draw and output until it cools.
