High-headroom Extension Cab The Supro 1732 Royale 1 x 12-inch Extension Cab is the perfect way to kick up your amplifier head's volume and headroom! Similar to the cabinet setup on Supro's Royale combo amps, this cabinet's increased projection and powerful volume are ideal for guitarists playing medium- to large-sized stages. A single Supro BD12 high-power driver is the core of this cab, sporting top-of-the-line suspension, a massive ceramic magnet, and a specialty British cone design to produce a chest-thumping midrange punch and pristine clarity. Moreover, GearNuts's pedal aficionados find that this cab's extended headroom and natural articulation make it the perfect platform for even the most convoluted of stompbox setups. Every great amp head needs a top-tier cab to match, and whether you're completing your Royale collection or simply looking for a fresh new tone for your head, the 1732 Royale 1 x 12-inch Extension cab does it all
