"Adopting the same principles of portability and simplicity that made Samson's Expedition XP308i so popular, the Expedition XP510i is an all-in-one portable PA system that offers outstanding power and convenience. The pro-level performance of the XP510i begins with a pair of dual 2-way speakers with 10-inch woofers, complemented by a 1-inch titanium tweeter in a 60¬? x 90¬? horn. These speakers will provide dynamic low-end qualities and broad dispersion in any performance space."
