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 RELs engineers.

Power is of little use unless properly directed. The filter circuit used in G-1 is the fastest REL 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, REL 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 REL 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.

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.
