Yamaha Installation Series Professional Speaker Package for Live Sound
in Theater Halls, Churches, Live Venues, Meeting Rooms and Schools

This Yamaha Installation Series professional loudspeaker package was custom designed by our expert audio engineers as an excellent addition or upgrade to any live sound system. This package includes two Yamaha IF2112/AS 2-way 12" loudspeakers, one IS1118 18" subwoofer, and two UB2112 speaker mounting U-brackets designed for wall mounting the IF2112/AS loudspeakers.

The Yamaha IF2112/AS multi-purpose high output 2-way loudspeakers feature a 12" woofer and an asymmetrical horn. The result is exceptionally clear and uniform high-frequency sound over a wide listening area. Dispersion can be controlled by rotating the horn in 90-degree increments, allowing the speaker to easily be installed even in cramped locations with either vertical or horizontal mounting. The Yamaha IS1118 high output subwoofer system is comprised of a single 18" woofer and is an ideal match for IF2112/AS full-range speakers for maximum power and full-spectrum reproduction. The IF2112/AS for left and right placement combined with the IS1118 subwoofer system is an excellent choice for small venues, not only for music systems but for spoken word applications as well.

• A wide selection of dispersion characteristics for long-range, short-range, and long/short-range use

• Suitable for an audience up to 400 people

• Recommended amplifiers/processors: (2) Yamaha XP7000 2-Channel Power Amplifiers and (1) Yamaha SP2060 Speaker Processor

This professional live sound loudspeaker package can be customized to fit the exact needs of your specific live sound application. Our audio engineers recommend using two Yamaha XP7000 power amplifiers with this speaker package. They also recommend adding West Penn 227 audio speaker wire to connect the speakers to the subwoofers.
