Markbass MB58R Energy 104 4X10 800W 8 Ohms

MB58R: Markbass's Approach to "Big Sound, Light Weight"

With the MB58R series, Markbass pursues a simple idea: to offer a "pro" cabinet sound and an impressive power reserve while drastically reducing weight and size. The MB58R 104 ENERGY fits this philosophy by combining custom neodymium speakers, a portability-oriented design, and Made in Italy manufacturing, all with special attention to materials and environmental impact.

For Which Bassists and Situations?

The MB58R 104 ENERGY clearly targets the bassist who wants a 4 x 10-inch cabinet capable of covering most contexts: intense rehearsals, club gigs, stages with powerful monitors, or studio sessions when seeking precise and articulate mic capture. Its high sensitivity helps achieve a lot of perceived volume without pushing the amp excessively.
Regarding styles, it excels in anything requiring attack and clarity : rock, funk, pop, fusion, modern metal, gospel, as well as pick playing. The tweeter and horn also make slap and harmonics more present while maintaining a solid low end for deep lines.

Design and Features: Efficiency, Focus, Stacking

This model is based on a proven architecture: 4 x 10 inches for quick response and punch, plus a 1-inch driver with horn to extend the high-frequency spectrum. The crossover set at 3.5 kHz ensures coherent distribution between the speakers and the tweeter, maintaining stable definition when increasing volume.
The choice of a rear bass-reflex port enhances the sense of depth in the lows, with better "settled" bass when the cabinet is placed at a reasonable distance from a wall. And if you play on larger stages, the advantage of an 8-ohm version is clear: you can add a second 8-ohm cabinet to increase dispersion, headroom, and stage presence while keeping a simple-to-manage setup.

Sound Character

The MB58R 104 ENERGY offers a decidedly modern signature: firm lows, controlled low-mids, and precise high frequencies. The 10-inch speakers provide a fast and percussive character that highlights right-hand attack and note clarity, particularly appreciated in dense mixes (guitars, keyboards, energetic drums).
The stated frequency response of 35 Hz to 20 kHz allows room for 5-string basses and lower tunings while leaving space for clean highs suited to modern techniques (slap, tapping, effects). Depending on the head used, you can go from a very "hi-fi" clean sound to a rougher grain: the cabinet then maintains good definition without compressing, thanks to its power handling and efficiency.
