Gibraltar G-1 transforms the definition of deep bass for the home. Whether used singly in multiples, we know of no finer ambient space and deep bass reproducer. G-1 combines shocking speed and clarity with formidable power handling and depth. G-1 combines a cabinet of remarkable complexity, with a power amplifier capable of sufficient current production to develop even the lowest, sustained passages—whether in ultra high-end home theater or the finest audiophile music system. And it all starts with the fastest filter circuits ever fitted to a home subwoofer. The bass note is then shaped and toned through truly environmentally friendly recycled blue jean material used as damping, and explodes outward through an ultra light, stiff carbon fibre 12” bass engine unique to G-1.

The massively beautiful, finned, alloy heatsink is necessary when dissipating the sorts of power necessary for prodigious deep bass for hours on end. Capable of outputting a conservative 600W (120V) on occasion, the dedicated REL Class A/B amplifier used in G-1 is a true dreadnaught. Powerful, fast and capable of tremendous current delivery, it is the finest amplifier ever designed by our engineers.

Power is of little use unless properly directed. The filter circuit used in G-1 is the fastest we know of in existence. Measured at just 4 milliseconds of group delay, this design features a 2nd order Bessel function crossover that begins as low as 20 Hz, necessary because G-1 can extend lower than that in many rooms. Additionally, we employ a secondary filter set at approximately 220Hz to roll off any remnants of midrange that might otherwise be audible.

Finally, G-1 possesses a dedicated Dolby .1 LFE input with its own 4th order crossover set at the Dolby mandated 120Hz and we outfit this circuit with its own separate volume control allowing G-1 to simultaneously reproduce the deepest bass for main speakers as well as home theater signals, all without having to invest in separate subs for each purpose. Additionally, G-1 provides independent volume for High level as well as .1 for perfect flexibility.

The 12” bass engine fitted to every G-1 features ultra light, stiff carbon fibre—the same stuff used to craft racecar chassis – as weight goes down, speed goes up. power production is handled by a large 4-layer Kapton voice coil capable of dissipating 700 watts, while the superior travel of the long-throw high energy suspension produces awe inspiring volume levels in your home.

Whilst 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 dynamics for which G-1 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 handcraft. The resulting structure is far more than a beautiful form, it is the barrel from which G-1’s awesomely deep bass fires.

When the Best Is Not Enough

Live bass does not live at floor level alone. It emerges, sometimes gently, sometimes with violence, in sheets and clouds. Live bass strikes our bodies from head to foot and pressurizes in ways no single sub can effect. It is for this reason that we have made available special connectivity allowing the use of multiple units, typically stacked in towers and rails that provide stability and limit the likelihood of scratching the finish on lower course Gibraltar in a tower. For the finest systems, the appropriate stack of G-1 or G-2 is the memorable and deserving final touch that transports the listener on a journey they will never forget.

To make tuning and setting up G-1 just a little easier, we fitted it with a beautiful remote control hewn from solid billet aluminium that replicates the standard analog control functions normally hardwired to the REL rear panels. We even covered the bottom with red felt because when you are finished setting it up, you will wish to place it on top of your G-1 to admire its form and quality. As with all REL active subwoofers you won’t need to use the remote again because a primary benefit of REL’s unique filters is that it allows true set and forget use.

As with all modern REL designs, we are singularly conscious that G-1 customers demand designs as comfortable gracing the interiors of the finest homes as winning lavish praise from the most critical reviewer. G-1’s form is simple, lovely and elegant, while the solid aluminium feet, badge and thick solid back plane all speak to the quality and simplicity of truly timeless design.
