Full-Power 4×10 Performance in a Touring-Optimized Chassis
The 4B10L is the highest-output cabinet in the Bass Instinct Series Neo/Lite line — four 10-inch neodymium-magnet woofers paired with a 1.4-inch compression driver, housed in a calibrated Italian Lightweight Plywood enclosure. Designed and built in California, the 4B10L delivers 1200 watts of RMS handling at 101 dB sensitivity, in a chassis weight optimized for international touring schedules.
Trusted by touring professionals whose itineraries are defined by fly dates, festival crossings, and intercontinental schedules, the 4B10L brings full-power 4×10 performance into a configuration designed for the realities of regular travel.
What it does
Four 10-inch neodymium woofers and a 1.4-inch compression driver in a calibrated Italian Lightweight Plywood cabinet. 1200 watts of RMS handling at 101 dB sensitivity. 45 Hz–18 kHz frequency response. Selectable 4-ohm or 8-ohm operation. Gig Armor™ Textured Black finish completes the visual continuity with the rest of the line.
“The 4B10L is engineered for the touring schedule that involves regular flights, multiple international dates, and intensive load-in/load-out cycles. Italian Lightweight Plywood and neodymium drivers together reduce the chassis weight without compromising the cabinet voicing or the power handling. For the bassist whose work includes regular fly dates, the 4B10L is engineered for that life specifically.” — Mike Lera, Head of Engineering & Design
