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