F12

The demands on modern high-performance systems regarding 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 comparably 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 conventional 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 amplifier. Only employing a 160 Hz Lo-Cut filter is recommended 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 RS426A), Even when employed as stand-alone cabinet, the

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

F9

The F9CWH is an extremely powerful and yet compact Mid/Hicabinet that has been designed for medium and long-throw applications. The Constant Directivity horn HT94 is coaxially aligned in a conical mid-frequency horn and offers a nominal radiation angle of 90° x 40°, which provides extremely smooth transmission without distressing interference in the x-over frequency range between the mid and high-frequency horns.

The mid-frequency range is reproduced by an Electro-Voice DL 12ST speaker system, while high frequency reproduction is taken care of by an Electro-Voice DH2T driver with titanium diaphragm, which is renowned for his excellent vocal definition and crystal-clear treble sound. The SPL of 105dB/1W/1m allows almost doubling the throw-capability of conventional direct-radiating loudspeaker cabinets.

Employing at least two Lo-cabinets per side – e.g. two F5 or two F118 – for bass sound reproduction is recommended to match bassSPL to the exceptionally high efficiency of the F9CWH.

(also refer to “Xa5-System” in the Application Guide on page 54).

F120

By designing its 2-way speaker system F120, DYNACORD set a new standard for professional 12" 2-way cabinets. A sound pressure level of 100 dB, wide coverage and its excellent sound quality make the F120 equally suitable to be used as full-range cabinet or as Mid-Hi component in active 2-way applications. When comparing the F120 to conventional 12" 2-way speaker systems, it provides nearly double the throw and power as well as a convincingly natural reproduction of vocals. An Electro-Voice DL12 ST 12" speaker serves a s woofer system while an Electro-Voice DH2T driver with titanium diaphragm and HT94 Constant Directivity horn provides exceptionally powerful mid-range sound and crystal-clear trebles. The newly designed frequency x-over is furnished with halogen lamps and thermal-breakers, which provide reliable protection against overload. The system-switch on the connection board allows easily configuring the F120 for full-range operation or connection to DYNACORD system power amps like the PM 2600 or Xa2600. The carrying handles are prepared for retrofitting a TÜV-approved rigging-kit to allow trouble-free “flying” applications.

F150

A professional 15" 2-way cabinet offering optimal sound, low weight and an outstanding price-performance ratio – that was the challenge for our engeneering. A sound pressure level of 102 dB, wide coverage and its excellent sound quality make the F150 equally suitable to be employed as full-range cabinet or as Mid-Hi component in active 2-way applications offering an convincingly natural reproduction of vocals. An Electro-Voice DL15Y 15" speaker serves a s woofer system.

An Electro-Voice DL12 ST 12" speaker serves as woofer system while an Electro-Voice DH2T driver with titanium diaphragm and HT94 Constant Directivity horn provides exceptionally powerful mid-range sound and crystal-clear trebles. The newly designed frequency x-over is equipped with halogen lamps and thermal-breakers, which provide reliable protection against overload. The system-switch on the connection board allows easily configuring the F150 for full-range operation or connection to DYNACORD system power amps like the PM 2600 or Xa2600. Frontal protection is provided through a robust steel grille that is covered with acoustic foam. The carrying handles are prepared for retrofitting a TÜV-approved riggingkit to allow trouble-free “flying” applications.

F5

The F5 is a compact, but yet high-efficiency subwoofer system. An EV DL15Y woofer works in the optimally vented cabinet, ensuring highest power handling, efficiency and low distortion. The integrated passive PowerMax x-over (x-over frequency 160Hz) features a parallel output and an additional crossover output offering trouble-free parallel or x-over operation when combined with professional full-range or Mid-Hi cabinets. Reliably protecting the woofer against critical peak levels and thermal overload are a thermal breaker and professional halogen lamps. The 4-pole SPEAKON-type connectors wired-through, allowing active system installations that employ DYNACORD system power amps PM2600 or Xa2600 for instance can be set up using 4-pole SPEAKON-type cables, without the risk of inadvertent mismatching. Four extremely robust castors are located on the cabinet’s rear and four ergonomically optimised recessed handles facilitate handling and transportation. Frontal protection is provided through a robust steel grille that is covered with acoustic foam.
