Dynacord Cobra-Pwh Subwoofer

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.
