User manual ALTO ATTIX 360-2M SPARE PARTS

[. . . ] Attachment points for the optional MTC-29UB U-bracket allows for compact installation and is particularly useful for low profile underbalcony applications. The woofer's cone is made of kevlar, surround is pure butyl rubber, and the driver basket is rear loaded to minimize direct exposure. The compression driver's diaphragm is pure titanium. The grille is thermoset composite coated and comes with foam to minimize incursion of water. [. . . ] Nickel/zinc rust-resistant terminals ensure a secure input connection. An MTC-PC2 sealed-entrance cover is included to further protect the speaker's terminals. ALTO's exclusive SonicGuard overload protection is virtually inaudible to the listener, ensuring reliability while providing full fidelity sound. Available in black or white (-WH). The cabinet will accept a variety of paints to match any décor.

Serviceable internal fuse to protect during exceptional overload conditions. Environmental: IEC 529 IP-X4 splashproof rating. Exceeds MilSpec 810 for humidity, salt spray, temperature & UV. Termination: Screw-down terminal strip, zinc plated copper base, nickel plated metal screws/washers. Accepts up to 9 mm outside 4 mm inside open lug (#6, #8 or #10 lug), plus bare wire (up to 12 AWG/2. 5 mm2). The compression driver shall be horn-loaded to cover 110 degrees by 85 degrees with a high degree of accuracy and the horn shall be rotatable to achieve these coverages either in the horizontal or vertical planes, regardless of cabinet orientation. The cabinet and grille shall be paintable. The grille shall be secured via screws to keep it in place when facing downward. The low frequency transducer shall have woven kevlar cone and butyl rubber surround, with the frame protected from direct weather exposure. The compression driver shall be constructed with a titanium diaphragm for weather resistance. The system shall withstand Mil Spec 810 testing with specified durations with no effect on its acoustical performance or structural integrity: salt spray (method 509. 3), temperature (method 501. 3 and 502. 3), humidity (method 507. 3) and ultraviolet (method 505. 3). Further, it shall pass Mil-Std-202F (method 101D) for salt spray. The system shall have an IEC 529 splashproof rating of IP-X4. For theft-deterrence, the installation access area shall be hidden behind a snap-out cover on the front grille. [. . . ] For theft-deterrence, the installation access area shall be hidden behind a snap-out cover on the front grille. The included ball mechanism shall be internal to the cabinet. The cabinet shall have ten (10) 6 mm mounting points, including 2 on each side and 3 on top and bottom and an accessory U-bracket shall be available. The grille logo shall be rotatable for proper orientation with loudspeaker mounted horizontally or vertically. [. . . ]
