The C4-TOP is a coaxial hornloaded mid / high frequency loudspeaker and its narrow dispersion characteristics of 35° x 35° above 700 Hz allow for clear and intelligible sound reproduction over long distances at very high SPLs. This focusing of sound into a narrow beam is of special benefit in acoustically critical situations. The C4-TOP cabinet is constructed from marine plywood and has an impact resistant paint finish, steel handles and MAN CF4 stud plate rigging points. The front of the loudspeaker cabinet is fitted with catches at the top and bottom for securing an optional wooden lid, and mounted on the rear panel are ratchet strap guide plates, two hinge plates and four heavy duty wheels.
The d&b audiotechnik loudspeaker range is designed exclusively for operation with d&b amplifiers. These provide power as well as comprehensive control and protection functions tailored to achieve the performance, reliability and longevity associated with the d&b System approach. The d&b D20 and 30D amplifiers are recommended to drive the C4-TOP. The d&b D80, 10D, D6 and D12 amplifiers can also be used with the appropriate loudspeaker configuration selected.
