Cerwin-Vega SUBA15-SLA83 15” Powered Subwoofer for SLA83 Line Array System

The Cerwin-Vega SUBA15-SLA83 15-inch Powered Subwoofer is engineered to be the versatile low-frequency engine behind the SLA83 line array system. Designed for professional sound reinforcement applications including live performance, touring productions, corporate events, houses of worship, and installed systems, this powered subwoofer delivers deep, controlled bass with the unmistakable authority that defines Cerwin-Vega performance.

At the heart of the SUBA15-SLA83 is a high-excursion 15-inch woofer featuring a robust 75mm high-temperature voice coil. Housed inside a precision-tuned bass reflex cabinet, this design maximizes efficiency while delivering tight, articulate low-frequency output. The result is impactful, musical bass response that provides a solid sonic foundation without sacrificing clarity at higher sound pressure levels. Whether deployed in compact venues or scalable array configurations, this 15-inch powered subwoofer delivers reliable, professional-grade performance.

The SUBA15-SLA83 does more than produce bass—it serves as the integrated power hub for the SLA83 system. Equipped with a built-in dual-channel digital amplifier delivering 400 watts at 8 ohms per channel, this unit provides clean, optimized power directly to compatible SLA83 passive modules. The amplifier is engineered exclusively for the SLA83 line array, allowing up to two SLA83 passive units to connect seamlessly. This integrated approach simplifies system design, reduces the need for external rack amplification, and ensures perfect crossover alignment.

Integrated DSP processing further enhances performance by delivering precise signal management and optimized frequency response. This intelligent control ensures cohesive blending between the subwoofer and the full-range array modules, creating a balanced, high-fidelity sound reinforcement system that is both powerful and refined.

Flexibility is built into its architecture. Fully compatible with the SLA83 three-point suspension system, the SUBA15-SLA83 supports both flown and ground-stacked configurations, allowing sound engineers to adapt quickly to venue requirements. Whether suspended in a compact array or deployed as a ground-supported system, integration remains fast, secure, and efficient.

Constructed from premium multi-layer plywood and finished with a rugged, wear-resistant polyurea coating, the enclosure is built to withstand transportation, demanding installations, and repeated touring use. This durable cabinet ensures long-term reliability while maintaining consistent acoustic performance.

For audio professionals seeking a compact yet powerful 15-inch powered subwoofer with integrated dual-channel amplification and SLA83 system compatibility, the Cerwin-Vega SUBA15-SLA83 delivers scalable performance and streamlined deployment.
