A new name in bass

Audiofrog is a new company founded by seasoned veterans of the car audio world, all of whom have extensive experience as custom installers. They know the ups and downs of installing subwoofers in cars and trucks, and they know what's needed to create great bass.

Performance is the goal

Audiofrog engineered and built their GB12D4 12" subwoofer with performance in mind. It starts with a 3", four-layer voice coil made to withstand the heat generated when a sub's working hard. The cast aluminum basket uses special venting to help dissipate this heat, enabling this sub to handle up to 500 watts RMS. Its extended low-frequency response means it can reproduce truly low notes without compromise.

A sub for small enclosures

The GB12D4 is optimized to work in compact enclosures — as small as 0.75 cubic feet for a sealed enclosure — so you can bring powerful bass into a tight space. Its high sensitivity means that your amp won't have to work so hard to bring you those thumping lows. Another nice touch from Audiofrog — an external switch lets you switch the sub's impedance from 2 to 8 ohms without rewiring.

Serious testing

Audiofrog subjects its speakers to rigorous testing, pulling random subs from the production line to check their ability to withstand abuses of heat, vibration, and power. A unique copper ring shields the mammoth 3" voice coil, minimizing the distortion found in traditional designs. It's this attention to real-world detail that makes Audiofrog subs unique, as they're designed by people who really know car audio.
