Features
Overview: The OSD Forza-850T is an in-ground, 2-way omni-directional speaker designed for distributed 70V and 8Ω audio systems in home and commercial outdoor applications. The in-ground omni speaker is an ideal choice for a variety of landscapes ranging from backyards to amusement parks, providing a full 360˚ of sound dispersion.
Construction: The Forza-850T 2-way in-ground speaker features an 8" polypropylene cone woofer and a 1" Mylar whizzer cone tweeter mounted in a high-impact, resin fiber enclosure. This combination provides deep bass and detailed highs in a wide 360˚ dispersion pattern for broad area coverage.
70V & 8Ω Operation: The OSD Forza-850T features a built-in 60 watt 70V transformer for commercial applications. An 8Ω bypass also allows it to be used in a "standard" speaker configuration with up to 200 watts RMS power handling. A tap-dial located beside the down-firing 2-way driver provides selections for the following:
- 70V: 20W, 40W, and 60W.
- 8Ω: Bypass
Wire Connection: Wiring connection to the Forza-850T speaker is made using the 30" section of jacketed 16-gauge speaker wire attached to the bottom of the enclosure. Direct burial wire is recommended for connecting the speaker and is sold separately.
Landscape Mounting: The Forza-850T is constructed with weatherproof components that are resistant to rain, snow, insects, and dirt, making it ideal for open outdoor spaces. The outdoor speaker should be partially buried, making sure the down-firing driver is exposed.
Note: The OSD Forza-850T is weatherproof, but is not designed to be fully submerged in water.
