Nashville, TN (March 9, 2015)—The OPA-181SP is a new, high output, low frequency subwoofer from One Systems, Inc. as part of its On Point Audio brand.
Intended for use in professional bi-amp applications, the new subwoofer features an 18-inch low frequency transducer; it is optimized for use between 35Hz and 80Hz. Peak system output of 127 dB SPL is achieved when 4th order filters are implemented.
One Systems states that the subwoofer sports a rectangular enclosure geometry with a larger internal volume than conventional trapezoidal enclosures, reportedly resulting in increased low-frequency response.
The input section consists of a single four-position barrier strip. The system impedance is 8 ohms. Multiple M10 rigging points allow for either vertical or horizontal eyebolt suspension. The enclosure is built with high strength, void free plywood and finished in On Point Audio’s Power Coat polyurea resin coating.
