The Keiron Series: FBT's "Installation" DNA in a Discreet Format
The FBT Install Keiron 8S B is part of the Keiron series, a range focused on integration, where priority is given to sound coherence, visual discretion, and ease of deployment in permanent installations. Its white finish and compact size address common constraints in public environments: refined aesthetics, reduced footprint, and streamlined implementation. In its passive version, it naturally fits into centralized audio architectures (rack amplification, external processing, zone distribution).
Who Is the Keiron 8S B For and What Are Its Applications?
This passive subwoofer is intended for integrators, service providers, and operators who want to add solid bass foundation to ambient or reinforcement sound systems without switching to an active subwoofer. It is particularly suitable for installations where the amplifier and processing are already defined (DSP, active crossover, matrix), and where precise adjustment of the cutoff frequency and bass level according to the room is desired. Thanks to its omnidirectional coverage, the bass spreads naturally, facilitating placement in constrained spaces (under benches, in corners, near walls), though validation according to the venue's acoustics is recommended.
