Historical Context and Positioning in the Range
Designed in the spirit of the MB58R series, this « 122 P » speaker stands as a versatile 2x12 cabinet, designed to combine the acoustic pressure of dual 12-inch speakers with optimized weight. The suffix « P » indicates the use of a piezo tweeter, a simple and reliable solution to extend the high frequencies without adding weight to the system. This model holds a prime position for bassists seeking a modern, powerful, and easy-to-transport 2x12.
Who This Amp Is For
Ideal from the
rehearsal room to the
stage, this cabinet suits intermediate and advanced bassists who want a single enclosure capable of covering rock, funk, pop, fusion, gospel, or melodic metal. In the
studio, its balanced response helps to place the bass in the mix without excessive boom. Live, its 4 Ohm impedance fully leverages an amp head to achieve a high SPL level with good dynamic headroom.
Features and Innovations
The MB58R 122 P combines two 12-inch ceramic speakers for body and projection, with a
piezo tweeter designed for attack definition, slap, and pick playing. The
bass reflex enclosure enhances low frequencies while preserving responsiveness in the low mids. The
3.5 kHz crossover ensures the transition between woofers and tweeter. With
600 W RMS at
4 Ohms, it handles current amp heads effortlessly and remains physically manageable thanks to its compact dimensions and 18.1 kg weight.
Sound
This speaker delivers a
deep and tight low end,
present mids that cut through the mix, and a precise treble without harshness thanks to the piezo. The 12-inch ceramic drivers provide an
organic grain with beautiful natural compression when the volume is pushed. The clean tone remains spacious and articulated, the crunch is punchy and musical, and the
headroom reserve facilitates dynamic lines as well as sustained grooves.
