The MASK4T loudspeaker has a unique innovative design and its transparent sound offers incredible intelligibility ideal for background music and paging purposes. MASK4T can be used in low impedance 16 ohms (up to 4 loudspeakers in parallel on a standard 4 ohms amplifier channel) or in 100 volt with several power tappings (20 – 10 – 5 – 2.5 watts).The cabinet is made of high quality enforced PPE ABS. The grille is made of aluminium and the woofer has been coated so MASK4T loudspeakers are suitable for both indoor and outdoor use. The cabinet is supplied with a rubber IP protection cover for the loudspeaker terminals. This way water ingress and corrosion of the terminals is avoided (IP64).MASK4T has a powerful 4.25” coated paper cone woofer. Together with the Vari-throat horn for the Ferro-fluid cooled 1” silk dome tweeter this results in a high SPL and ultra low distortion. Its phase alignment and wide frequency range makes sure every note, starting from the robust low-mid over the clean middle range to the crystal clear highs, reaches your ears with an astonishing clarity.The built-in Auto-Reset 3-step Protection Guard together with the quality components makes MASK4T a fail-safe loudspeaker, even at high power loads!Thanks to the Intelli-Mount bracket, the MASK4T is easy and fast to install. The Vari-throat horn for the tweeter and the 5° down tilt angle in which the woofer and tweeter are mounted in the cabinet, guarantee a perfect sound dispersion, without the need of a big tilt angle of the cabinet itself. The cabinet has a M8 thread mounting point tapped at the back of the cabinet. This way many other mounting systems can be used.The MASK4T loudspeakers can be painted in any colour.
