Performance is the goal

Audiofrog GB10D4 rear view

The GB10's massive vents help keep things cool.

Audiofrog engineered and built their GB10D4 10" 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 1000 watts RMS. Its extended low-frequency response means it can reproduce truly low notes without compromise.

A sub for small enclosures

The GB10D4 is optimized to work in compact enclosures — as small as 0.5 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.

To drive this single subwoofer, we recommend a mono amplifier rated between 750 and 1500 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Features

Dual Voice Coils: This woofer features two 4Ω voice coils, with a switch on the terminal, allowing you to easily change from parallel (the woofer presents a 2Ω load) to series (the woofer presents an 8Ω load) wiring.

Screw Terminal: The set screw terminals offer easy connection of bare wire up to 8 gauge. A 3mm Allen wrench (not included) is needed to tighten the terminals.

Sealed Box Volume: The recommended sealed box volume range is from 0.5 ft³ to 0.75 ft³, with 0.6 ft³ being the ideal size. A sealed enclosure design gives the smoothest response with increased energy at the lowest frequencies.

Ported Box Volume: The recommended ported box volume range is from 0.85 ft³ to 1.75 ft³. The ideal size is 1.0 ft³, for which both slot and tube style port measurements are given; both result in a tuning frequency of 33 Hz:

  • Slot: 11" x 1" opening, 17.5" long
  • Tube: 3" diameter x 13" long

Power Handling: Audiofrog lists two RMS power figures in the manual; 500 watts RMS in the technical specifications section and 100-1,000 watts RMS in the recommendations section. We've listed the recommended range in the specs table.

Crutchfield asked: Why did you buy this?

Designed for small enclosures even when vented [ Chris  Oct 28, 2016 ]
A
Andy Wehmeyer's (AudioFrog cofounder) reputation in the car audio industry [ Jesse  Jun 04, 2016 ]
A
Looked at all the options that were best suited for my setup and the adviser was great with explaining the product and if for any reason I was not satisfied I had 60 days to return the sub. I have been purchasing equipment from Crutchfield for a long time and they have always backed up there products as well as the support at any given time. Awesome and more to come on how the sub performs when I get it installed. [ LARRY  Mar 09, 2016 ]

Q
Since it is 4-ohm dual voice coil, I only see a single connection. How do you wire it into 2-ohm?
[ Stan M.  May 24, 2017 ]
1 answer
A
There's a switch so you can configure 2 or 8 ohm with one connection
