{"product_id":"fbt-install-keiron-8c-b-black-422574","title":"Keiron 8C B Black","description":"\u003ch3\u003eThe Keiron Series: An \"Install\" Approach by FBT\u003c\/h3\u003e\u003cp\u003eDesigned for fixed sound reinforcement needs, the \u003cstrong\u003eKeiron\u003c\/strong\u003e series focuses on consistent coverage, tonal coherence, and ease of integration. The \u003cstrong\u003eFBT Install Keiron 8C B\u003c\/strong\u003e fits this logic with a compact format, 2-way coaxial configuration, and installation-oriented connectivity. Its size allows it to be integrated into spaces where aesthetics and discretion matter as much as intelligibility, while maintaining true level capability for professional use.\u003c\/p\u003e\u003ch3\u003eWho Is the FBT Install Keiron 8C B For?\u003c\/h3\u003e\u003cp\u003eThis passive speaker is a relevant choice for \u003cstrong\u003einstallers\u003c\/strong\u003e, integrators, and venue operators seeking reliable sound distribution: meeting and conference rooms, retail stores, restaurants, cultural spaces, public venues, reception areas, or as nearfield reinforcement in larger installations. Thanks to its 80 deg x 80 deg coverage and sensitivity of \u003cstrong\u003e96 dB (1W\/1m)\u003c\/strong\u003e, it can deliver good efficiency with a suitable amplifier while maintaining controlled reproduction in reverberant environments.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003e2-way coaxial\u003c\/strong\u003e configuration is particularly interesting when aiming for a more coherent sound image (closely aligned acoustic sources) and more even dispersion over the listening area, especially at short to medium distances typical of wall-mounted installations.\u003c\/p\u003e\u003ch3\u003eDesign and Performance: What Makes the Difference\u003c\/h3\u003e\u003ch4\u003e2-Way Coaxial Architecture: Coherence and Precision\u003c\/h4\u003e\u003cp\u003eThe Keiron 8C B features an \u003cstrong\u003e8-inch (203 mm)\u003c\/strong\u003e driver with a \u003cstrong\u003e2-inch (51 mm)\u003c\/strong\u003e voice coil, paired with a \u003cstrong\u003e1-inch (25 mm)\u003c\/strong\u003e tweeter with a \u003cstrong\u003e1.4-inch (36 mm)\u003c\/strong\u003e voice coil. This coaxial architecture aims for better phase coherence and a single-source sensation, which helps maintain a natural and intelligible listening experience, particularly useful for speech, announcements, and ambient music content.\u003c\/p\u003e\u003ch4\u003e80 deg x 80 deg Coverage: Even Dispersion\u003c\/h4\u003e\u003cp\u003eWith an \u003cstrong\u003e80 deg H x 80 deg V\u003c\/strong\u003e dispersion, the speaker is designed to effectively cover a defined area while limiting unnecessary spill. This type of directivity facilitates installation work (orientation, multiple diffusion points, level management) and helps maintain good clarity in spaces where acoustics can be challenging.\u003c\/p\u003e\u003ch4\u003eLow-Frequency Management in Installation: Recommended Filtering\u003c\/h4\u003e\u003cp\u003eThe stated frequency response of \u003cstrong\u003e60 Hz to 20 kHz\u003c\/strong\u003e is well suited for ambient and reinforcement applications. To optimize power handling and limit unnecessary stress in the extreme low frequencies, a \u003cstrong\u003erecommended high-pass filter\u003c\/strong\u003e at \u003cstrong\u003e50 Hz - 24 dB\/oct\u003c\/strong\u003e is advised. The use of an \u003cstrong\u003eexternal filter\u003c\/strong\u003e is also recommended via \u003cstrong\u003edigital management\u003c\/strong\u003e (with presets depending on configuration) to adapt the curve and protection to the venue's constraints.\u003c\/p\u003e\u003ch4\u003ePlywood Enclosure and Wall Integration\u003c\/h4\u003e\u003cp\u003eThe \u003cstrong\u003eplywood\u003c\/strong\u003e cabinet provides a solid base for installation, with a rigidity that benefits precision. For mounting, an \u003cstrong\u003eadjustable bracket sold separately (WM-45)\u003c\/strong\u003e is available, convenient for adjusting the dispersion angle and accurately targeting the listening area.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cstyle\u003e@media(max-width:632px){table[data-wb-spec]{display:grid;grid-template-columns:minmax(0,1fr)
