Know before you buy
Yes, this is a passive subwoofer, meaning it does not have a built-in amplifier. You will need to connect it to an external power amplifier capable of driving a 3 Ohm load.
Yes, the unit comes with dedicated wall and ceiling mounting brackets. It also features 8x M8 rigging points, providing secure options for permanent installations in various venue layouts.
The subwoofer is equipped with both a Speaker Twist connector and a screw jack input, offering flexibility for different professional audio wiring setups.
The Curv 500 ISUB is designed for fixed installations and smaller to medium-sized venues where 200 W RMS of low-frequency reinforcement is sufficient. For very large spaces, you may need to integrate multiple units to achieve the desired bass coverage.
Because the subwoofer has a 3 Ohm impedance, you must ensure your amplifier is stable and rated to handle loads lower than the standard 4 or 8 Ohms. Always check your amplifier's specifications to confirm it can safely drive a 3 Ohm load.
