Oslo Weatherproof 18" Subwoofer

$2,046.50 each
- +

The Oslo delivers accurate, extended bass in a single 18" driver design, and offers excellent efficiency in a ported design without the excessive port resonance and one-note bass sounds that plague many subwoofers.  Ports are flared to minimize port noise and enhance overall performance.

The Oslo's environment-impervious cabinet and stainless-steel grill, moisture shedding design, and Technomad's proprietary driver treatments combine to produce a subwoofer that can be installed in virtually ANY environment.  Whether extremely hot, extremely cold, high UV intensity, or permanently wet - such as ship-board uses - the Oslo shrugs off environments that destroy ordinary subwoofers in a matter of months.
