The rotatable high-frequency horn allows use of the speaker in either vertical or horizontal orientation. Consistent coverage ensures excellent sound character throughout the listening area. Moderate magnetic shielding allows use of the speaker as close as 230 mm (9?) to video monitors. The top-quality line distribution transformer, designed for minimal insertion loss and reduced saturation, allows use of either 70V or 100V distributed speaker lines. In bypass position, the 8? impedance allows use of multiple speakers on a loudspeaker line. The included InvisiBall mounting method is simple to install, aims easily and provides a high degree of theft deterrence. InvisiBall allows horizontal rotation of up to 41 off-axis and vertical rotation of up to 36 (horn end inward) or 23 (woofer end inward). Attachment points for the optional MTC-29UB U-bracket allows for compact installation. Weather resistance has been maximized. 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. JBL's exclusive SonicGuard overload protection is virtually inaudible to the listener, ensuring reliability while providing full fi delity sound.
