Our take on the Boston Acoustics G312-44

The G3 Series subwoofers from Boston Acoustics incorporate innovative technologies with advanced materials for low-frequency firepower that'll enhance any type of music. The patented RadialVent® cooling system shunts heat away from the voice coil, and the ultra-rigid chassis provides a rugged platform for high-powered bass.

The G3 Series subwoofers from Boston Acoustics incorporate innovative technologies with advanced materials for low-frequency firepower that'll enhance any type of music. The patented RadialVent® cooling system shunts heat away from the voice coil, and the ultra-rigid chassis provides a rugged platform for high-powered bass.

The 12" G312-44 dual voice coil subwoofer features a rigid copolymer woofer cone and a large compressed foam surround. Extended cone excursion lets these subs pound out ultra-low notes, while the 2-1/2" voice coils handle 375 total watts RMS for bass that hits hard. Boston's unique SureSet™ fuse configuration makes it easy to switch the total impedance between 2 and 8 ohms, and it protects the voice coils from overload when the music is cranked.

This multi-purpose sub works well in all sizes and types of enclosures. You can install this sub with Boston's GTR Tunable Radiator for a big boost in bass level without a large enclosure. The gasket allows for standard and inverted mounting so you can get creative with your installation.

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most 2-channel car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation. Most mono amps are stable down to 2 ohms.

Priced per speaker

Have had one of these for a year now, absolutely awesome, been pushing 2000W to on sub and it takes it allll! Just bought another one so I cant wait to hear them both, loudest clean hitting sub I've ever heard for a single 4 ohm

Features

Chassis: The Boston Acoustics G3 series high-performance subwoofers are built upon a rigid chassis. It features the patented RadialVent cooling technology which directs airflow around the 2-1/2-inch 4-layer voice coil for increased power handling.

Materials: The G312-44 woofer has a co-polymer woofer cone with a raised dustcap and a large compressed foam surround. The wrap-around gasket gives you a good seal whether you top-mount or bottom-mount the woofer.

SureSet: The speaker terminals are equipped with two 7.5-amp ATC fuses for selecting between series or parallel voice-coil operation. When both fuses are used, the woofer is configured for parallel operation, and the woofer's impedance is 2 ohms. When one fuse is used in the center slots, the woofer is configured for series operation, and the woofer's impedance is 8 ohms. There is no need to change the position of the speaker wire in order to switch between parallel and series wiring. The fuses also provide voice coil protection under transient conditions such as accidental momentary overdrive. Use of the standard automotive style fuses allows you to quickly service the woofer in case a fuse is blown during usage. Note: The fuses do not protect against voice-coil failure resulting from long term high power abuse.

Terminals: The woofer has rugged spring post terminals that accept up to 8-gauge bare wire or pin connectors.

Long Excursion: The woofer has a 2-3/4 inch peak-to-peak excursion for accurate deep bass output from a small sealed enclosure.

GTR Tunable Radiators: The G312-44 is compatible with the Boston Acoustic GTR Tunable Radiator (item number 065GTR12, sold separately). These passive radiators, when mounted in an enclosure with the G3 woofer, can produce increased bass output without added enclosure volume.

Enclosure Recommendations

Sealed Enclosure: The ideal sealed enclosure for the G312-44 woofer is 1.0 cubic feet.

Ported Enclosure: The woofer can also be used in a 2.0 cubic foot ported enclosure with a 4" diameter x 13" long port (tuned to 34 Hz).
