The IF2112/AS is multi-purpose high-power 2-way speaker systems. The IF2112/AS features a 12-inch woofer and an asymmetrical horn (hence the “AS” designation). 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. A single control allows you to easily switch the speaker between bi-amp mode, which provides greater sonic control and superior quality, than passive mode. The new installation series speakers address a number of important issues that give them unprecedented performance and handling characteristics for live sound applications, including permanent installations. In particular, phase characteristics have been kept smooth and consistent throughout the entire series, so you can mix and match speakers to suit any system and venue without ending up with hot and dead spots due to phase interference. And of course sonic quality is superb throughout the entire reproduction range so the full impact of the source material reaches the audience undiluted. This approach to design is evident in every Yamaha commercial audio product. The proof is in the enormous success of our groundbreaking PM1D and PM5D digital consoles, digital signal processing products and industry-standard analog live consoles and related gear. Yamaha is simply dedicated to delivering the best sonic performance available anywhere, at any price, from system input to output. Our new installation series breaks new ground once again with performance and convenience that can take the sound at any venue to a higher level.
