DYNACORD´s COBRA-SUB is a vented direct radiating cabinet, equipped with the high-power Electro-Voice EVX 180B 18" transducer.
Frequency response is 38Hz - 170Hz (-10dB), so the crossover frequency to Mid-Hi cabinets, e.g. DYNACORD´s COBRA-TOP can be chosen strictly application-oriented between 80Hz and 160Hz. 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-SUB 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-SUB against damage during transport and bad environmental conditions. The connector panel uses two 4-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 two Speakon connectors.
When using DYNACORD power amp racks, the whole system can be wired with 4-pole Speakon cables without any danger of accidental wiring mistakes. Four recessed rigging tracks and two webbing-strap points can be used for easy “flying” of the COBRA-SUBs. The cabinet is equipped with four large ABS feet that allow easy stacking and a “snap-on flying” even in angled positions. Two handles and four heavy-duty castors on the rear side guarantee easy and safe transport.
