The Defender 1x12 is a solidly constructed guitar speaker cabinet with a single Kustom® 12-inch speaker. It handles 30 watts RMS and is rated at 16 ohms. The speaker itself is designed to produce rich, articulate clean tones and yet responds well to overdriven signals. The cabinet utilizes a speaker baffle board made of plywood, which provides enhanced resonance.

The Defender 1x12 speaker cabinet is also a great sonic match for the Defender 5H all-tube, 5-watt guitar head.
