The Sub118 is an all purpose, 18 inch, vented subwoofer that is designed to provide extended low frequency support in a wide variety of installations. Its premium, high power transducer is physically engaging, yet is musically articulate enough to reproduce the subtlety and harmonic nuance of an upright bass or the low strings of a piano. The Sub118 requires digital signal processing, and many platforms are supported. The Sub118 is an excellent option any time a compact subwoofer with robust SPL capability is needed. This makes it the perfect choice for medium-sized houses of worship and theatres, and for distributed low frequency reinforcement in nightclubs, restaurants, and theme parks. It is also well suited for use in DJ booths and as a VLF channel in A/V screening rooms or for multimedia playback. The 18 inch woofer in the Sub118 has a high power, 4 inch voice coil, and is capable of impressively large excursion. The enclosure is optimally tuned to provide maximum low frequency output in a compact package.
