Full-Range 2x12 Bass Power With Serious Portability
The Mark Bass MB58R 122 ENERGY is an 800W 4 ohm bass cabinet designed for players who want strong output, clear definition and manageable weight in a compact 2x12 format. Its two 12" Markbass neodymium custom speakers deliver punchy low-end response, while the 1" driver with custom horn adds definition through the mids and highs.
This cabinet is voiced for a full, flat-response sound, making it useful for bassists who want their playing, instrument and amplifier character to come through clearly rather than being heavily coloured by the cabinet. The 45Hz to 20kHz frequency response and 103dB sensitivity give the MB58R 122 ENERGY the range and efficiency needed for rehearsals, stages and demanding live setups.
At 17.5kg, the MB58R 122 ENERGY offers a strong power-to-weight ratio compared with many traditional high-powered bass cabinets. Its rear reflex design supports low-end movement, while the 800W RMS power handling gives players plenty of headroom for modern bass amps.
At Riffs & Licks Music, we think the MB58R 122 ENERGY is ideal for bassists who need the authority of a 2x12 cabinet with defined highs, punchy lows and a lighter build that makes regular gigging more practical.
