The Control 30 utilizes high power components, computer optimized horn and coaxial component design, patent-pending cabinet manufacturing techniques, anda complex network to achieve smooth high fidelity performance, extended bandwidth and well-controlled, defined coverage from a compact loudspeaker.A symmetrical mid-high frequency horn allows use of the speaker in either vertical or horizontal orientation. Smooth frequency response and cone-midrangeperformance ensures excellent sound character throughout the frequency band, over the entire listening area.The top-quality line distribution transformer, designed for minimal insertion loss and reduced saturation, allows use of either 70V or 100V distributed speakerlines. In bypass position, the 4 ohm 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 upto 41° off-axis and vertical rotation of up to 36° (horn end inward) or 23° (woofer end inward). Attachment points for the optional MTC-30UB (-WH) U-bracketallows for compact installation and is particularly useful for low profile under-balcony applications. Color: Black.
