G1 MKII represents a study in contrast. Familiar yet different—visibly unchanged better in every way than the original G1 Rels best-selling reference sub. Retained is the classic curvilinear cabinet with its shape carefully engineered to cancel standing waves as they travel rearward through the cabinet. The laminated hardwood bracing reminiscent of musical instruments still finds a home—though re-configured for even greater rigidity. The amplifier is the powerful yet highly controlled and ultra-reliable 600w Class A/B with new limiters that allow almost 40% more power being delivered without compression.The driver—the heart and soul of any REL– has been dramatically upgraded with greater fore-and-aft stroke a more supple suspension and the ability to handle greater dynamics. This new version is now capable of 112 dB output. expands the performance horizons of the original in every way whilst retaining its core strengths of dignified beauty coupled to even more savage output.
