The Phonic IW810 is a high fidelity 8 inch (diameter) in-ceiling loudspeaker with built-in transformer. The 8" mid-range speaker offers an exceptional wide frequency response of 80 Hz to 12 kHz for superb low-to-mid-range audio reproduction in a low-weight package. Rated input is 10 Watts at 100V, while the 20 Watt maximum power handling available make it ideal for high ceiling installations such as those found in restaurants, shopping centers and gymnasiums. Perfect for background audio systems as well as talk-over systems - with crystal clear voice reproduction - the IW810 can be integrated into most ceilings and drywalls.
