British speaker icon KEF today announced a major expansion of its subwoofer lineup that brings a powerful new 11-Hz-capable dual-driver model into play and introduces a series of sealed subwoofers. The new Kube MIE series includes single-driver 8-, 10-, 12-, and 15-inch subwoofers at prices ranging from $600 to $1,400 but the star of the show is the $2,000 KC92, a larger and more powerful step-up to the KC62 subwoofer that received a Sound & Vision Top Pick in 2021.
