Dynacord COBRA-PWH 18″ – 600W. @ 8Ω, (RMS.) Planar Waveguide, Horn Loaded, Line Array Subwoofer.

The Dynacord COBRA-PWH Speaker 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.

FEATURES
