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 GB12D2 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 1000 watts RMS. Its extended low-frequency response means it can reproduce truly low notes without compromise.

A sub for small enclosures

The GB12D2 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 set the sub's impedance from 1 to 4 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 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

The next level up

I upgraded from an SA12 to this but have also had JL Audio W3v3, Alpine SWS, and many more. All great subwoofers in their classes but these GB series are something special. I have this in a custom ported 1.8 cube box and it sounds insanely great. So glad I went with this. I originally wanted the GB12 D4 but it was backordered for months so I modeled this GB12 D2 in BassBox Pro and it actually modeled better with its higher sensitivity. I have this paired with the GB15/GB60 combo, full active, and man it sounds so good I want to just drive just so I can listen to it. It has insane output and no distortion.

Pros: Sound quality and SPL all in one. High quality components and doesn't weigh too much. Simple black cone doesn't draw attention to itself.

Cons: You need to tin the speaker wires or the set screws will cut the wire. Not a big deal though just not addressed in the manual.

The Perfect Subwoofers

Matthew from St Louis, MO on 4/6/2017

Have two of these in a custom 3 cubic foot ported box in the back up my Jeep Grand Cherokee. Upward facing, running off their own Arc Audio XDi 1100.1 at 1 ohm. I bought these subs because I wanted a good mix of SQ and SPL but more SQ. I have had them for a little over a month now and I am so blown away with the performance of these "SQ" subs. Absolutely amazing subs, definitely recommend for anyone wanting a SQ sub that will sound like a SPL sub. These things POUND!

Highs/Mids = Hertz Mille's Digital Processor = Audison Bit One Amp = Audison AV 5.1k Review: Currently I'm testing these speakers w/my installer before we build a fancy custom box, have to make sure you like before you commit to a box right? I have two of these woofers, the first box was built to Audiofrog spec with a single port as MDF for material...remember, just testing. Anything 37-40'ish Hz was terrible and caused the woofers to sound blown. My installer got a hold of some key players at Audiofrog and they spent about a week building boxes and testing but I'm finally glad to say the box can safely get to 35Hz using a dual port design and it absolutely slams. A frequency sweep revealed the subs start to disappear around the 32-33Hz with my AV 5.1K wired at 1-ohm. Dual 15" Hertz Energy/Dual 12" Hertz Hi-Energy subs were tested as well but couldn't outperform the Audiofrogs once properly configured. Value - Not the cheapest but they can outperform most bigger conventional subs. Sound Quality - This is one of the reasons I didn't give up on them after our issues and go straight to a JL W7. I'm a bass-head but I didn't want my Mille's to be over powered by SPL so when the bass is turned down they sound nice and responsive. Ease of Use - Switch to change the Ohm's is nice but box specs were an issue Coolness Factor - The front of the woofers have nothing on them to identify it (you can use the JL mesh grill covers btw) Build - UNK but

Pros: - Potential Build Quality - Good Responsiveness - Ability to perform louder than expected

Cons: - Box dimensions/performance outcome can be tricky - Won't win any SPL competitions but these are considered "Audiophile" - MSRP is $699 which I would have never have paid but I think this is a fair price

Product Research

Features

Dual Voice Coils: This woofer features two 2Ω voice coils, with a switch on the terminal, allowing you to easily change from parallel (the woofer presents a 1Ω load) to series (the woofer presents a 4Ω 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 0.75 ft³ to 1.25 ft³, with 1.02 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 1.35 ft³ to 2.5 ft³. The ideal size is 1.5 ft³, for which both slot and tube style port measurements are given; both result in a tuning frequency of 33 Hz:

  • Slot: 12-1/2" x 1-1/2" opening, 22" long
  • Tube: 4" diameter x 16" 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.
