LD Systems 10 inch SUB: Compact Installation Subwoofer

The LD Systems CURV 500 ISUB is a high-performance, low-profile installation subwoofer designed specifically to complement the CURV 500 array system. Engineered for discreet permanent installations, it provides a powerful low-frequency extension while maintaining a shallow cabinet depth, making it ideal for mounting on walls or ceilings in cafes, restaurants, and corporate spaces. The ISUB utilises a custom-designed long-throw transducer to deliver punchy, accurate bass from a compact enclosure.

Professional Low-Frequency Performance

The CURV 500 ISUB is equipped with a 10-inch high-excursion woofer with a 2.5-inch voice coil. It is designed to handle 200 Watts RMS (400 Watts Peak) and provides a frequency response down to 47 Hz. The shallow-depth cabinet design (only 135 mm deep) allows it to be installed in tight spaces where traditional bulky subwoofers would not fit. Despite its small footprint, it delivers a maximum sound pressure level of 120 dB, ensuring it can provide significant low-end support for background or foreground music systems.

The enclosure is constructed from 15 mm MDF and finished with a durable, textured paint. It features a professional Euroblock connector for secure wiring and multiple integrated M8 rigging points for various mounting options. The speaker is available in both black and white finishes, allowing it to blend into different architectural designs without drawing attention away from the room's aesthetics.

Integration and System Design

Designed as a passive subwoofer, the ISUB is perfectly matched with the CURV 500 I AMP or other professional amplifiers. Its 4-ohm impedance allows for efficient power transfer from modern installation amplifiers. The inclusion of a dedicated wall-mounting bracket ensures a secure installation, and its low profile makes it particularly effective for under-seating or surface-mount applications.

For larger installations, multiple ISUB units can be deployed to ensure even bass distribution throughout a venue. This modularity, combined with the compact array satellites of the CURV 500 series, provides a scalable and high-fidelity audio solution for premium commercial environments.

Includes low-profile wall and ceiling mounting bracket.
