Bring your music outside with the Boston Acoustics Voyager 4 Outdoor Loudspeakers. They feature 4.25" copolymer woofers and .75" Kortec soft dome tweeters that are specially voiced for excellent mid-bass and crystal-clear highs outdoors. All Voyager enclosures, grilles, hardware and speaker components are designed and treated to stand up to weather and temperature extremes. Heavy-duty aluminum C-brackets are included, and the wedge-shaped enclosures make corner mounting easy.
