Dynacord Cobra PWH 600w 18" Horn Loaded Cabinet Speaker
Dynacord COBRA-PWH 18" Horn Loaded Cabinet Subwoofer (COBRAPWH, COBRA PWH)
Dynacord COBRA-PWH 18" Horn Loaded Cabinet Subwoofer. 600W EVX 180B Transducer; 30Hz - 150Hz (-10dB); High-Efficiency Planar Waveguide Design; Voice Coil Tracking Protection.
DYNACORD´s COBRA-PWH is a Planar Waveguide Basshorn, equipped with the high-power Electro-Voice EVX 180B 18" transducer. Frequency response is 30Hz - 150Hz (- 10dB), so the crossover frequency to Mid-Hi cabinets, e.g. Dynacord's COBRA-4-TOP, COBRA-4-Far or COBRATOP can be chosen strictly application-oriented between 80Hz and 130Hz.
The cabinet is equipped with an electronic circuit called VOICE COIL TRACKING PROTECTION. This circuit senses the terminal voltage of the transducer and simulates the thermal behaviour of the woofer´s voice coil. In case of potential thermal overload the power applied to the speaker is reduced to a safe level. Power amps up to 1200W/8Ohms can be used in order to have maximum dynamic range without the danger of thermal overload in non-controlled situations. The VOICE COIL TRACKING PROTECTION exhibits “soft” switching characteristics, so no annoying clicks or pops are audible. The circuitry automatically resets after the voice coil temperature has reached a safe value.
The COBRA-PWH cabinet is made of 18mm birch plywood. All corner joints and braces are grooved and glued. The cabinet´s surface is coated with an extremely durable Polyurethane which exceeds the quality of a standard lacquer finish by an order of magnitude. A powder coated steel grille and a lockable cover protects the COBRA-PWH against damage during transport and bad environmental conditions.
The connector panel uses two 4-pole and two 8-pole Speakon connectors (IN/OUT) for a safe connection and easy daisy-chaining to other cabinets. The pin assignment is 1+/1-. Pins 2+ and 2- are also connected between the respective two Speakon connectors. When using DYNACORD power amp racks the whole system can be wired with 4-pole or 8-pole Speakon cables respectively, without any danger of accidental wiring mistakes.
Pins 1+/1- and 2+/2- of the 4-pole Speakon connectors and 8-pole Speakon connectors are wired in parallel, so COBRAPWH cabinets can also be connected with 4-pole Speakon cables in COBRA-4 systems. Four webbing-strap points allow an easy securing of the COBRA-PWH cabinets. The cabinet is equipped with eight large ABS feet that allow easy “snap-on”stacking in horizontal or vertical set-ups. Six handles and four heavy-duty castors on the rear side guarantee easy and safe transport.
