4" installation speaker for background music, 20 W AES, 16 ohm The INTUCAB 4FW50T is a wideband background music speaker for indoor applications where a discreet appearance and mechanical ruggedness must be combined with an above-average sound pressure level and impeccable sound quality. With an impedance of 16 ohms, this model is perfect for low-impedance applications with up to four speakers in parallel. The optional transformer kit also facilitates integration into 100-V systems. To simplify cabling in fixed installations, an additional 5.0-mm terminal strip is included in the delivery. The mounting options include M6 and M10 mounting points that enable suspended mounting, truss mounting and bracket mounting. Available in black and white textured finish for even greater flexibility. For full-range applications, usage in combination with the INTUCAB 8SM300T subwoofer is recommended.
