Direct radiator subwoofer Dynacord SUB18

Dynacord SUB18 is a subwoofer equipped with a powerful Dynacord LFS 18700 driver, which is designed for use as a subwoofer in active multi-way systems. The classic design with a vented direct driver guarantees excellent transient response and allows the SUB 18 to be used in medium and large format bass arrays. The woofer uses a long excursion voice coil to ensure low distortion even at high speaker levels. The 100mm sandwich voice coil is highly durable and can withstand very high power peaks. The cabinet is equipped with an electronic Voice Coil Tracking Protection circuit, which detects the voltage at the transducer terminals and simulates the thermal behavior of the woofer's voice coil. In the event of possible thermal overload, the power supplied to the speaker is reduced to a safe level. To obtain maximum dynamic range without the risk of thermal overload, very powerful amplifiers can be used in uncontrolled situations. Voice Coil Tracking Protection has smooth shifting characteristics so there are no annoying clicks or other noises. The circuit automatically resets once the voice coil temperature reaches a safe value. The SUB 18 body is made from 18mm birch plywood. All corner joints and brackets are grooved and glued. The surface of the body is painted with 2-K varnish. A powder-coated steel grille with protective acoustic foam on the back protects the LFS18700 from damage and harsh environmental conditions. The connector panel uses two 4-pole Speakon connectors (INPUT/THRU) for reliable connectivity and easy daisy-chaining with other cabinets. Four handles ensure easy and safe transportation. For portable use, an optional four-caster wheel kit is available that can be screwed to the rear wall.
