GB Series Sculptured Spherical 8" Omnidirectional

GB20T
Penton Audio GB20T is a refined spherical omnidirectional loudspeaker system finished in white. Having a diameter of just 10" this decorative system has a 30-watt, 8" treated, twincone loudspeaker protected with an opaque dust screen. Omnidirectional in design, it exhibits a true 360-degree angle of coverage in the horizontal plain.

The attached pendant mounting has a 116" long, 5-conductor, braided cable capable of holding at least 10 times the unit's weight. Its entire length is covered by a white jacket that perfectly matches the cabinet.

Well suited for distributed audio, it has a 20-watt, 70.7-volt transformer. Tap selection is made at the pendant cable's ends (see specifications).

To keep the GB20T looking new, the white ABS enclosure has molded-in UV inhibitors.
