On Point Audio’s OPA-181SP is a high output, high performance 18-inch subwoofer that delivers the perfect combination of deep bass response, high output capability and installation flexibility. The OPA-181SP is equipped with a high performance 18-inch woofer built by On Point Audio that’s equipped with a large-format 4-inch (101 mm) voice coil. This woofer provides 800 watts continuous, 3,200 watts peak power handling while delivering 127 dB continuous, 133 dB peak output capabilities. The subwoofer’s enclosure is precisely tuned to provide usable low-end response to 30 Hz for bass you can feel as well as hear. OPA-181SP’s enclosure is built of industrial-grade 13-ply birch plywood, finished in On Point Audio’s rugged PowerCoat finish. The OPA-181SP is equipped with heavily reinforced M10 suspension points that enable it to be safely suspended. The OPA-181SP’s enclosure is more compact than typical 18-inch subwoofers, enabling it to be less conspicuous when it’s installed, whether ground-stacked or flown.
