RCFSUB 15-AX W Professional Active 15" Subwoofer White
1/6
Independent shopping perspective
The Korena take
The white SUB 15-AX W concentrates on active low-frequency reinforcement from 35Hz to 120Hz. Its 15-inch woofer, 2,200W peak amplifier, and 133dB maximum SPL suit live-performance and recording setups needing dedicated lows. A touchscreen and encoder give direct access to crossover presets, 8-band EQ, delay, routing, and cardioid-output configuration, letting you adjust the sub within a larger system. The stackable multi-ply hardwood cabinet has a polyurea coating, side handles, and a threaded pole mount for practical transport and deployment.
Strong match
Who this is for
- Live-performance or recording systems needing dedicated low-frequency reinforcement from an active 15-inch subwoofer.
- System setups requiring crossover, equalization, delay, routing, or cardioid-output adjustments.
- Touring and rental deployments that benefit from a stackable cabinet and side handles.
Consider the trade-offs
When to look elsewhere
- Applications requiring subwoofer response outside the specified 35Hz–120Hz range.
