The Keiron InWall Series: An "Installation" Approach Designed for Integration
The FBT Install Keiron IW 5C B belongs to the Keiron InWall series, designed to meet the constraints of fixed projects: visual integration, clean recessed installation, and performance adapted to installed sound systems. Made in Italy, it fits into a logic of durable equipment for spaces where effective sound reinforcement is expected without cluttering the architecture.
Intended Uses and Environments
This speaker is particularly suitable for fixed audio installations where discretion and clarity are paramount: restaurants, hotels, shops, meeting rooms, cultural venues, reception areas, corridors, and traffic zones. Its recessed format allows maintaining a clean aesthetic while ensuring controlled sound presence.
Thanks to its 93 dB sensitivity and compact size, the Keiron IW 5C B is also suitable for systems requiring multiple moderate-level distribution points, for example to achieve even coverage without having to increase volume excessively. It can also be integrated into more elaborate configurations with external processing when optimizing equalization, protection, and filtering is desired.
Coaxial Design, Controlled Directivity, and Easy Integration
2-Way Coaxial Architecture: Precision and Coherence
The 2-way coaxial configuration combines a woofer-midrange driver and a tweeter on a common axis. This design choice promotes coherent reproduction, with a stable sound image and good intelligibility, a key point for voice applications (announcements, conferences, mediation) as well as background music.
The specified driver is a 2-inch (voice coil 1.5 inch ) complemented by a 1-inch tweeter (voice coil 1 inch ). The entire system is designed to offer precise rendering in a discreet wall format while maintaining usable performance in an installation context.
90deg x 90deg Coverage: Homogeneity in Near Field
With a 90deg H x 90deg V dispersion, the speaker targets balanced coverage, useful when distributing multiple speakers in a space to achieve more uniform diffusion. This directivity facilitates the design of a diffusion grid, especially in areas where level differences from point to point need to be minimized.
Low Frequency Management: Recommended Filtering and System Optimization
The stated frequency response ranges from 80 Hz to 20 kHz. To secure operation and improve power handling in the low spectrum, a recommended high-pass filter at 70 Hz with a slope of 24 dB per octave is advised. The internal crossover frequency is specified at 3 kHz.
For further optimization, a recommended external filter such as an FBT DSP Processor is mentioned. In an installation, a DSP can help adapt reproduction to the room, protect transducers, and homogenize multiple zones, especially when multiple diffusion points are used.
Amplification and Wiring: Designed for "Install"
The Keiron IW 5C B is a passive speaker with input connectors on a terminal block, a standard appreciated in integration for reliable connections. The 60 W RMS power and 240 W Peak power are accompanied by a recommended amplifier of 120 W, allowing for dynamic headroom depending on use and desired level. The nominal impedance of 16 ohms also simplifies some multi-speaker deployments, provided wiring rules and the amplifier's minimum load are respected.
