The Control 29AV-1 provides improved voicing for extremely flat, high fidelity performance, extended bandwidth and well-controlled defined coverage from a compact loudspeaker. 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 9" (230 mm) 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-ohm impedance allows use of multiple speakers on a loudspeaker line. The 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).Weather resistance has been maximized in the Control 29AV-1 speaker. The woofer"s cone is made of kevlar, surround is pure butyl rubber, and the driver basket is rear loaded to minimize direct expo
