Design and build

The passive subwoofer PRX418S is a representative of the well-known American company JBL. Simplicity of design, increased reliability and the use of advanced high-tech solutions is a hallmark of the entire acoustics of this company. The housing of the PRX418S is made of birch plywood and coated with a special protective coating DuraFlex, which will provide high wear resistance and additional protection against scratches. On the back of the case there is a patch panel slightly recessed inward, consisting of two Neutrik Speakon NL-4 connectors (IN / THRU). When using a separate crossover or low-pass filter, the THRU connector allows you to transfer the filtered signal to high-frequency speakers, which will save amplifier channels and cable products for switching. The entire front panel of the case is closed with a removable perforated metal grill, transportation handles are provided on the side faces, and a glass for an acoustic stand is provided on top of a 35 mm glass. The body of the subwoofer is made of poplar or birch wood, as well as multi-laminate (hardwood). Additional driver protection is provided by transparent foam covering the grilles from the inside.
