The MB58R 104 P brings four 10-inch classic ceramic speakers and a piezo tweeter into a bass cabinet rated for 600W RMS under the AES standard. At 47 lb, its enclosure material is designed to keep the cabinet easier to take to gigs than its speaker count might suggest. The listed 40Hz–18kHz response, 102dB SPL sensitivity, and 3.5kHz crossover provide the key figures for building a compatible bass setup.
