15-Inch Subwoofer for Car and PA Audio

This 15-inch subwoofer delivers 220W RMS and 450W max power for deep, consistent bass. It is built for car audio systems and PA DJ speaker setups. The 4 Ohm impedance ensures compatibility with most car amplifiers. A 40 Oz Y30 ferrite magnet provides strong magnetic force for clear, distortion-free low frequencies.

Integration with Amplifiers and Enclosures

The 4 Ohm impedance allows straightforward wiring to a wide range of car amplifiers. A 2-inch CCAW voice coil handles high power while maintaining durability during extended play. The 91 dB sensitivity rating means the driver produces louder output with less amplifier strain. Builders must supply a suitable enclosure and amplifier matched to the 220W RMS rating.

Power Handling and Frequency Limits

The subwoofer operates from F0 up to 3 kHz, covering deep lows through mid-bass for rich reproduction. Continuous power handling sits at 220W RMS with peaks to 450W max. The 40 Oz Y30 magnet and steel frame keep the voice coil controlled at high excursion. Systems requiring output beyond 3 kHz or sustained power above 220W RMS will need additional drivers.

Questions about this item

How much continuous RMS power can the 15-inch WF 15 140 4OHM handle before thermal limits appear?

The subwoofer is rated for 220W RMS continuous power handling, which is the sustained level the voice coil and 40 Oz Y30 magnet structure are designed to dissipate.

What is the sensitivity and impedance of the WF 15 140 4OHM when driven all day in a sealed enclosure?

It presents a 4 Ohm load and produces 91 dB sensitivity, so the amplifier runs cooler and draws less current for a given output level during extended sessions.

Which amplifier specifications must I already own to match the 4 Ohm impedance and 220W RMS rating of this subwoofer?

You need an amplifier stable at 4 Ohms that can deliver roughly 220W RMS into that load, with speaker-level or line-level inputs to drive the 2-inch CCAW voice coil.
