F12

The demands on modern high-performance systems re- garding their long-throw capability, low distortion, and intelligible sound are constantly growing. The introduction of DYNACORD’s patented Planar Waveguide technology marks a quantum leap in the field of high-efficiency, direct radiating subwoofer systems.

Typical long-throw systems offer extreme throw on the cost of a comparably small directivity angle, so that several cabinets need to be employed to provide coverage of the entire audience area.

The Conical Waveguide horn F 12 CWH is a very compact Mid/Hi-component offering an immense SPL and a com- parably wide radiation pattern. The speaker components are coaxially mounted, which provides a smooth extended frequency response within the entire radiation range.

In the Mid-Bass range works an ELECTRO-VOICE DL12 ST high-performance transducer mounted on a Conical Wave guide horn. The high-frequency range above 800 Hz is reproduced by an ELECTRO-VOICE DH6-8 driver, firing into a coaxially mounted 80°x55° wide coverage horn.

This coaxial design ensures extreme linear transmission, without the occurrence of Dead-Spots as they are usually found with conventional systems.

F 12 CWH offers excellent long-throw coverage, stable intelligible sound and superb performance.

The F 12 CWH represents a truly economic solution for a wide range of applications in festival tents, halls and at medium-size open-air events when compared to conven- tional long-throw systems (e.g. 35° x 35°) and because of its wide radiation angle of 80° x 55° and its superior medium and long-throw capability. Despite its wide coverage, the Conical Waveguide design awards the F 12 CWH with an on-axis sound pressure level that is identical to that of a typical long-throw component.

FREQUENCY RESPONSE USAGE

The sound of the F 12 CWH provides is marked through its noticeably high dynamic range with comparably low distortion. The linear frequency response between 100 Hz

–19 kHz (-10 dB) is as excellent as its SPL of 106 dB 1W/1m and the cabinet’s off-axis sound is still impressively neutral and uncoloured.

Integrated in the cabinet is a passive horn-EQ, which allows using the F 12 CWH for vocal reproduction when directly connecting it to any common linear power ampli- fier. Only employing a 160 Hz Lo-Cut filter is recommen- ded to protect the 12” horn system against low-frequency overload.

THROW CAPABILITY PROTECTION

Because of its exceptional level of efficiency and outstanding power handling capacity of 350 W (EIA RS- 426A), Even when employed as stand-alone cabinet, the

Multi-stage protection circuitry guards the F12CWH driver systems from being damaged by thermal overload.
