GoldenEar SuperSub X Subwoofer$1,499.99
Like the SuperSub XXL, the ultra-compact SuperSub X (just a little bigger than a 12-1/2′′ cube) utilizes the same dual-plane, patented* inertially-balanced driver array, but instead employs two horizontally-opposed 8 ̋ ultra-long-throw active drivers and two vertically-opposed 10-1/2 ̋ x 9-1/2 ̋ planar back-wave-driven radiators, driven by a 1400 watt Class D Digital amplifier.
