FBT Install CLA 112S B

An "Install" version of the Vertus series, tailored for integration

With the Install CLA 112S Black, FBT offers a passive subwoofer that embodies the spirit of the Vertus series: professional performance in a format suited for integration. This "Install" version prioritizes operational reliability, mechanical stability, and resistance to field constraints, while maintaining a sound signature focused on impact and low-end control. Its solid aluminum design and protection-oriented construction (IP55) make it a relevant choice for venues where equipment must remain in place, operate for long periods, and stay discreet over time.

Intended uses and users

This passive subwoofer is primarily aimed at integrators, installers, and operators of public venues seeking a robust bass solution for a fixed installation. It naturally complements satellite systems in environments such as bars, restaurants, hotels, event spaces, cultural venues, or covered semi-outdoor areas. Thanks to its omnidirectional dispersion, it contributes to a homogeneous bass foundation, particularly useful when a consistent low-frequency presence is desired without noticeable "holes" depending on the listening position.

Design, protection, and performance: key points

Architecture designed for installation and durability

The Install CLA 112S Black relies on a robust construction with a solid aluminum body, an asset for rigidity, passive heat dissipation, and long-term mechanical endurance. Its IP55 rating provides additional protection against dust and water spray, reassuring in installations where the environment is not always perfectly controlled (frequent traffic, technical areas, moderate climatic constraints, cleaning).

Clean integration with secure connectors

In installations, connectors often make the difference. Here, the presence of Amphenol IP67 Euroblock connectors ensures a reliable, stable connection suited to the demands of fixed cabling. This is a real advantage to reduce false contacts, simplify maintenance, and secure operation over time, especially when the subwoofer is installed at height, inside an enclosure, or in a hard-to-access area.

Bass tailored with external filtering

The subwoofer is designed to operate with an external crossover (recommended filtering at 90 Hz with a slope of 24 dB per octave ). This approach gives the integrator the freedom to optimize the crossover with the main speakers according to the venue configuration, placement, and desired impact level. The recommended amplification of 600 W rms allows full exploitation of the 12-inch driver's potential while maintaining useful headroom for peaks and dynamic passages.

Impact, control, and clarity in the low end

Equipped with a 12-inch driver (305 mm) featuring a 4-inch voice coil (76 mm), the Install CLA 112S Black targets a low spectrum that is both present and controlled. Its 96 dB sensitivity facilitates achieving a substantial level, while the maximum level reaches 127 dB SPL continuous and 130 dB SPL peak. The frequency response extends down to 28 Hz, a value to consider depending on the external crossover settings, highlighting the importance of proper filtering and processing (DSP, equalization) in an installation.
