DYNACORD Sub 118 SUB 118 contains a passive fi lter that suppresses high frequencies.

DYNACORD´s SUB 118 is a vented direct radiating cabinet, equipped with the high-power DYNACORD LFS 18700 transducer. 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. 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. Extremely powerful amps 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 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. The pin assignment is 1+/1-. Pins 2+ and 2- are also connected between the two Speakon connectors. A recessed pole-mount fl ange allows easy speaker-on-a-stick applications. Please always take care that every speaker stack has been mechanically secured against accidental falling down. Please always consult a certifi ed structural engineer for correct and safe setup methods. The cabinet is equipped with eight large rubber feet. Four handles and four heavy-duty castors on the rear side guarantee easy and safe transport.
