12 Inch Home Audio Subwoofer

This 12 inch subwoofer delivers 120W RMS and 1200W peak power for home audio and DJ applications. Its 8 ohm impedance suits a wide range of amplifiers and PA systems. The unit uses a foam edge paper cone and a 1.5 inch CCAW voice coil for responsive bass reproduction.

Frequency Range and Sensitivity Limits

The driver operates from 40 Hz to 3.5 kHz with 89 dB sensitivity, covering deep bass through lower midrange. Output below 40 Hz rolls off naturally, so it does not replace a dedicated infrasonic enclosure. The 8 ohm load limits maximum amplifier power compared to 4 ohm designs.

Standard Installation and Common Issues

The speaker mounts using standard 12 inch cutout dimensions with an iron basket frame. The 30 Oz Y30 magnet adds weight, so secure all mounting bolts to prevent air leaks. Miswiring the 8 ohm terminals or underpowering the 120W RMS rating are the typical causes of distortion or coil overheating.

Questions about this item

Should I pick the 12 inch 8 ohm version or a different impedance?

This model is a 12 inch driver rated at 8 ohms with 120 W RMS and 1200 W peak, so choose it when your amplifier or speaker system requires an 8 ohm load.

What does 120 W RMS actually deliver in my cabinet?

120 W RMS means the woofer can handle continuous power of 120 watts without thermal damage, producing consistent bass down to 40 Hz at 89 dB sensitivity.

How does the 8 ohm impedance limit my amplifier pairing?

An 8 ohm nominal impedance presents a moderate load, allowing most home and PA amplifiers to deliver their rated output without current limiting or overheating.
