Blaze Audio BL218SSi-B – Dual 18" High-Output Sub-Bass Subwoofer, Black

Product Overview

The Blaze Audio BL218SSi-B is a high-output dual 18-inch sub-bass subwoofer designed as the primary low-frequency companion to the CCA10i line array system. Built for large-scale commercial sound reinforcement, it delivers the deep, sustained sub-bass output required for auditoriums, houses of worship, live performance venues, and large multi-purpose spaces. As a commercial subwoofer for sound reinforcement, the BL218SSi-B uses a front-loaded enclosure design to maximize output efficiency and transient response. It is part of the Blaze by Sonance CCA Series ecosystem, available from Creation Networks.

Product Description

The BL218SSi-B is the highest-output subwoofer in the Blaze by Sonance CCA Series system, housing dual 18-inch woofers in a front-loaded enclosure engineered for maximum low-frequency output and control. It is specifically designed to extend the low-frequency response of the CCA10i constant curvature array, providing the sub-bass foundation required for demanding commercial applications where intelligibility and impact must coexist. The front-loaded enclosure design ensures accurate low-frequency transient response and consistent performance across the operational bandwidth. Deployed in pairs or as standalone units, the BL218SSi-B scales to meet the LF demands of large auditoriums, worship spaces with significant seating capacity, and multi-purpose venues hosting live events. The black finish is appropriate for stage-deployed or floor-standing configurations in most commercial environments. Integration with the CCA10i line array is straightforward — the BL218SSi-B is engineered to match the acoustic output characteristics and deployment geometry of the CCA10i system. AV integrators specifying large-format commercial line array systems will find the BL218SSi-B an essential component for complete system performance. For installations requiring a single-woofer option, the BL118SSi-B offers the same design principles at a lower output tier. Both subwoofers are available at Creation Networks.

Frequently Asked Questions

What amplifier is required for the BL218SSi-B?
The BL218SSi-B requires a high-power commercial amplifier capable of driving dual 18-inch woofers. Consult the Blaze by Sonance datasheet for impedance and power handling specifications and use a DSP processor for proper crossover and system alignment.

Does the BL218SSi-B require DSP processing?
Yes. For correct integration with the CCA10i array system, DSP processing is required to manage crossover points, delay, and system alignment. This ensures optimal performance and protects the drivers from out-of-band excursion.

How many BL218SSi-B units are needed per CCA10i array?
The number of subwoofers required depends on venue size, SPL targets, and coverage requirements. Contact Creation Networks for system design assistance and recommendations based on your specific application.

Can the BL218SSi-B be used without the CCA10i array?
The BL218SSi-B is optimized for use with the CCA10i system but can function as a standalone subwoofer in commercial sound reinforcement systems. Consult Blaze by Sonance documentation for standalone deployment guidance.

What is the difference between the BL218SSi-B and BL118SSi-B?
The BL218SSi-B uses dual 18-inch woofers for maximum output, while the BL118SSi-B uses a single 18-inch woofer for installations with lower SPL requirements or tighter space constraints. Both are CCA10i companion subwoofers available at Creation Networks.
