The Supro 1791 1 x 15 Black Magick Extension cabinet is an ideal companion to the award-winning 1695T Black Magick amplifier.Sized to fit perfectly underneath the Black Magick combo amplifier, the 1791 is a partially open-back, vintage-style 1 x 15 extension cabinet loaded with a custom-made, Supro BD15 speaker, developed especially for this cabinet. This all-new high-power 15” driver combines the speaker cone found in our Supro Thunderbolt combo amplifier with the top-of-the-line suspension and huge magnet from the Black Magick speaker to achieve serious low- end punch and phenomenal mid-range projection.With the 1 x 15” extension cabinet connected along with the combo’s 12” internal speaker, the Supro Black Magick amplifier runs down at 4-ohms, developing maximum power from its Class-A output section. The Supro 1791 Black Magick extension cabinet adds considerable versatility for larger stages and pedal-based rigs where maximum headroom is required from a compact, vintage flavored combo.Specifications:• Supro BD15 Speaker• 75 Watts power handling• 8-Ohm Mono• Thunderbolt Cone• 2” Voice coil• 56oz Magnet• Pairs with: 1695T Black Magick• 20 1/2? x 18 3/4? x 8 3/4?• 52 x 47.6 x 22.2 cm
