The Martin Audio C4.8T (pair) are designed to be in-ceiling mounted and offer a two-way vented solution, ideal for discreet audio installations whilst maintaining optimum sound performance.
They incorporate a 4-inch UL94V-0 polypropylene low-frequency driver and a 0.8-inch dome tweeter, ensuring wide sound coverage with a 180° conical dispersion, making them particularly suitable for environments with low ceilings or requiring even sound distribution.

With a power of 40W RMS and a sensitivity of 86dB, the Martin Audio C4.8T ensure excellent sound clarity even at high volumes. They are also compatible with high and low impedance systems, thanks to an included line transformer, allowing use in 70V or 100V installations as required.

The passive crossover fixed at 5 kHz allows a smooth transition between low and high frequencies, optimizing audio quality.

The galvanized steel back box and perforated steel protective grille ensure resistance to harsh conditions, while the UV-resistant white frame can be repainted to match the aesthetics of the installation.
