The 1x15 Black Magick Extension cabinet was designed to match the Black Magick or Black Magick Reverb amplifier, in either head or combo format. The Black Magick Extension is a partially open-back, vintage-style 1x15 loaded with our custom BD15 high-power driver, offering the serious low-end punch and offering additional stage volume. It utilizes a specialty British cone, top-of-the-line suspension and an oversized ceramic magnet. With the 1x15” extension cabinet connected in addition to the combo’s 12” internal speaker, the Black Magick amplifier runs down at 4-ohms, developing maximum power from its Class A output section. The Black Magick Extension adds considerable versatility for larger stages and pedal-based rigs where maximum headroom is required.
