4" Premium Low Profile Ceiling Speaker (Blind Mount)


    The IsoFlare™ FC-4T LP is a wide bandwidth, high sensitivity ceiling loudspeaker designed for the ultimate in fidelity, coverage, and aesthetics. With a greatly reduced back can depth, the FC-4T has been engineered specifically for critical applications where ceiling cavity dimensions are restricted.

    The IsoFlare™ FC (in-ceiling) range is the new benchmark in point source technology for prestigious commercial environments. Leveraging years of engineering experience and the very latest in design & engineering techniques, IsoFlare™ brings performance and premium commercial audio to any space. FC models are available in a variety of sizes and with different installation methods to provide versatility for architects, designers, and installers.

    Unlike most ‘coax’ offerings, the IsoFlare™ driver exhibits excellent harmonic alignment between HF and LF sources, the effect of which is to deliver accurate and natural reproduction with superb tonal balance.

    The FC4-T LP exhibits surprising low end for its diminutive size.

    Propagating a spherical wavefront, homogeneously aligned on all axes, the IsoFlare™ point source driver yields an even response throughout the listening area; a constant time delay over the entire frequency spectrum providing exceptional off-axis performance.

    The FC-4T LP is designed for applications requiring a combination of premium sonic quality for music and speech reinforcement with exceptional reliability, in an architect/designer/installer friendly solution.

    Low frequency enhancement can be augmented with the FC-8ST ceiling subwoofer

    The IsoFlare FC-4T LP is supplied with C-Ring and Tile Bridges.
