Maine is know for occasionally hostile weather, so it should come as no surprise that a company based in Maine should develop an all-weather speaker designed to handle even the most extreme conditions. Terra speakers "All Climate" models use a molded one-piece enclosure, cast aluminum mid/bass driver baskets, titanium dome tweeters, and a spiderless magnetic fluid centering system for their bass drivers. Available in a variety of colors, they have a sound that is both well grounded and liquid. Priced around $330 each, the Terra AV series will make any ground squirrel stop and take notice.
