G2 (Discontinued)


Visually stunning, leveraging the design aesthetic of its larger sibling, G-2 provides the power and agility Gibraltar has come to be known for, at a more modest scale than our other reference subwoofers.

Additionally, orders placed from November 25th to November 30th will be processed when our office reopens on December 1st after the Thanksgiving holiday.

Power & Grace

G-2 is possessed of a lovely combination of dimensions looking “just right” in every setting. At home in rooms of modest scale or when used in stacked multiples it is capable of fearsome output necessary for larger rooms. Power has been throttled back to a conservatively rated 450W which, when coupled with the superbly fast and tuneful 10” carbon fibre bass engine employed within, is a winning combination. Naturally, we retain the same world beating filter and crossover set as in G-1. Fast, phase-correct Bessel filters with completely separate inputs and filtering for .1/LFE are part of G-2’s magical presentation of music and home theater. And then there is that lovely cabinet with 13 coats of lacquer and ideal dimensional multiples that eliminate interior standing waves.


Refined Craftsmanship

While the outer form garners all the praise—its 1 ¼”curvilinear surfaces slathered in no fewer than 13 coats of hand polished lacquer has a way of inspiring attention—it is the inner construction that produces the balance of speed and power for which G-2 is revered. The marine grade laminated hardwoods employed in the musical instrument-grade internal bracing  require two days of production time to complete a single unit. Each cabinet requires three weeks to hand-craft. The resulting structure is far more than a beautiful form, it is the crucible from which great music and theater emerges.


A Carbon Fibre Soul

The 10” bass engine fitted to every G-2 features ultra-light, stiff carbon fibre — the same material used to craft race car chassis – light weight results in greater speed. Power is handled by a large 4-layer Kapton voice coil capable of dissipating 500 watts, while the superior travel of the long-throw high energy suspension produces awe inspiring volume levels in your home.


A Classic Masterpiece

The massively beautiful, finned, alloy heatsink is necessary when dissipating the sorts of power necessary for hours of prodigious deep bass. Capable of outputting a conservative 450W the REL Class A/B amplifier used in G-2 is a masterpiece in its own right and is, in fact the amplifier from the original G-1, only with fewer output devices. Powerful fast and incisive, it remains one of the finest amplifier topology ever designed by our engineers.
