Extended Low-End Response in a Lighter Chassis
The 1B15L brings the deepest cabinet voicing in the Bass Instinct Series Cabinets line — the 32 Hz frequency response of the 1B15 Ceramic — into a neodymium driver and Italian Light Plywood configuration. Designed and built in California, the 1B15L is engineered for upright bassists, range-extended electric players, and orchestral pit musicians who require the displacement of a 15-inch driver in a chassis built for regular touring.
What it does
A 15-inch neodymium-magnet woofer paired with a 1.4-inch compression driver, in a calibrated Italian Light Plywood cabinet. 600 watts RMS handling, 98 dB sensitivity, 32 Hz–18 kHz response. Standard 8-ohm configuration with 4-ohm available by special order.
“For the upright bassist, a 15-inch driver isn't a stylistic choice — it's an engineering requirement. The acoustic upright produces fundamental frequencies that benefit from the displacement a 15 provides. The 1B15L is engineered to deliver that performance in a cabinet light enough to carry to the orchestral pit night after night. The neodymium driver, the Italian Light Plywood construction — all of it serves the upright player who values the lightest cabinet that still does the work.” — Mike Lera, Head of Engineering & Design
