This pair of Dayton Audio® IO65XTB 6-1/2-In. Indoor/Outdoor Speakers brings unprecedented audio fidelity outdoors. It challenges the notion that outdoor speakers lack low-end response. While it has a small enclosure, the IO65XT can produce surprisingly deep, tight bass response by using a passive radiator design. Each speaker features an active 6-1/2-in. polypropylene woofer and passive radiator woofer to deliver extended low bass response uncharacteristic of outdoor speakers. Its lightweight, treated 1-in. silk dome tweeter produces crystal clear highs resulting in full-range high fidelity performance. With a 70V/100V transformer tap, this speaker can be used in commercial installations such as distributed background music and paging systems in bars, hotels, restaurants, and conference rooms. In addition, the IO65XTB includes an 8-ohm bypass option for use with consumer amplifiers in residential applications such as pools, patios, gardens, and porches. The elegant enclosures can be mounted vertically or horizontally on walls or ceilings. Dayton Audio® has once again delivered extreme versatility, outstanding value, and exceptionally great sonic performance at an affordable price.
