The Nomad Three All-Weather & Surround Speaker is clean, compact, and sounds like it's ten times bigger than its size. Precisely what you'd expect from Parasound. The Nomad speaker system is designed to provide you with high-fidelity reproduction in a wide variety of home theater and outdoor applications. The polypropylene woofer and ferrofluid treated wide dispersion tweeter have been carefully constructed to resist the effects of hostile weather conditions. The cabinets are hermetically sealed and specially coated to resist the elements in harsh environments.
