Dynacord A 118 Passive 18 inch Subwoofer

 The new patented High-Speed-Laminar-Vent system shows signifi cantly less distortion and lower air noise at low frequencies than common vented cabinets. The SUB 118 contains a passive fi lter that suppresses high frequencies. Appropriate fullrange cabinets, e.g. DYNACORD’s D15- 3, can therefore be directly connected in parallel to the SUB 118 if an extended bass reproduction is required. You just have to connect the SUB 118 and the fullrange cabinet with a regular Speakon cable. 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. Extremely powerful amps can be used in order to have maximum dynamic range without the danger of thermal overload in non-controlled situations.  The circuitry automatically resets after the voice coil temperature has reached a safe value. The SUB 118 cabinet is made of 18mm birch plywood. All corner joints and braces are grooved and glued. The cabinet´s surface is painted with a 2-K laquer fi nish . The acoustic foam front on a powder coated steel grille protects the SUB 118 against damage during transport and bad environmental conditions. The connector panel uses two 4-pole Speakon connectors (INPUT/THRU) for a safe connection and easy daisy-chaining to other cabinets.
