Supro 1799 Black Magick Extension Ca

Overview of the Supro 1799 Black Magick Extension Cabinet

The Supro 1799 Black Magick Extension Cabinet was introduced in April 2021 and functions as a dedicated speaker cabinet designed for guitar amplification. This model features a pair of twelve-inch custom-made Supro BD12 speakers, offering a maximum load capacity of 75 watts. The cabinet is open at the back, and users can select between four-ohm or sixteen-ohm operation, broadening its compatibility with a variety of amplifier heads. Its moderate weight and careful design serve players seeking a balance between portability and sound performance.

Speaker Configuration and Sound Projection

At the heart of this model, two twelve-inch Supro BD12 speakers operate in tandem. Both speakers are custom-designed, an important point since proprietary drivers frequently shape the cabinet's sonic footprint. It's a setup intended to give a broad and articulate midrange, with twelve-inch drivers known for delivering substantial low-frequency response and midrange presence. The open-back construction has a clear impact: it creates a projection that provides not just focused forward throw, but also disperses some of the sound to the sides and rear, contributing to a sense of spaciousness and room-filling presence. This layout is well-suited to players seeking enhanced stage spread and natural resonance, rather than the tightly focused projection of closed-back designs.

Impedance and Power Considerations

One of the notable technical features is the selectable impedance, users can choose between four-ohm or sixteen-ohm operation from a single output jack. This flexibility allows for matching with a wide range of tube and solid-state amplifier heads. The power handling tops out at 75 watts; that figure indicates it is tailored to medium-power stage and rehearsal settings. Players using modern high-output heads will want to verify output to prevent overdriving the cabinet. For most vintage reissue amps or lower-wattage modern amplifiers, the handling rating aligns well with common performance requirements, ensuring the speakers can manage transients and sustained loud passages without premature distortion.

Physical Characteristics and Build

The Supro 1799 Black Magick Extension Cabinet measures 71 centimeters wide, 47.6 centimeters high, and 22.2 centimeters deep. These proportions make it relatively slim for a dual twelve-inch cabinet. The weight clocks in at 19 kilograms, a figure that is moderate for this configuration. This allows for manageable transport by one person when necessary, though the rectangular footprint is designed more for stage stability rather than ultra-compact portability. The cabinet has an open-back configuration. This build choice supports its goal of natural acoustic dispersion and dynamic interaction with performance spaces.

Compatibility and Use Cases

The single unit sale means it's built for stand-alone use or in combination with a matched head from Supro's Black Magick range, though the impedance switch also makes it compatible with a selection of third-party amplifier heads. The inclusion of custom twelve-inch speakers means that users will not hear the same voicing as with stock drivers from generic brands. This model's power rating of 75 watts aligns with traditional tube amps in the twenty-to-fifty watt class or select solid-state heads. It is not intended for use as a bass cabinet or with any application exceeding its maximum load.

Key Technical Points

• Custom-made twelve-inch Supro BD12 speakers provide signature sound tuning in a dual-speaker, open-back enclosure
• Selectable impedance (four-ohm or sixteen-ohm operation) increases amplifier compatibility
• Maximum load capacity of 75 watts is geared to guitar amps rather than high-power heads, and requires users to check compatibility in advance
• Open-back design supports broader sound dispersion and interaction with the ambient space
• Dimensions balance stage presence with transportability, at 19 kilograms and a 71 x 47.6 x 22.2 centimeter build

Technical Assessment

The Supro 1799 Black Magick Extension Cabinet is focused on sound spread and tonal flexibility. Custom Supro speakers, paired with a relatively light weight for a double twelve-inch cabinet, make it practical for performing musicians who need both classic tone and reliable stage output. The open-back format means increased room interaction and a less directed, less bass-heavy response compared to closed-back units. The selectable output impedance directly benefits players who may need to pair this cabinet with multiple amplifier types over time. Compared to generic designs at a similar price point, build attention is evident in its custom speakers and thoughtful enclosure proportions. However, the model is less suited to anyone requiring the tight sonic focus or maximum power handling of sealed or higher-wattage cabinets.

Summary

Supro's 1799 Black Magick Extension Cabinet fulfills its technical promise with custom dual twelve-inch drivers, impedance flexibility and an open-back layout. The power rating addresses medium-output needs, while physical design makes transport possible for working guitarists. The omission of stereo operation and the strict sixty-watt power limit set its role within traditional guitar rig setups. For players interested in classic tones, room interaction and versatile amplifier pairing, this cabinet aligns with Supro's dedication to performance-oriented design.
