This is marine audio at its best. The Nautica TS-MR2040 8" 2-way speaker is built specifically for marine use, with heavy-duty construction that strenuously resists water, corrosion, heat-and boring music. It features Pioneer's extremely strong yet lightweight IMPP Cone Woofer, for improved sensitivity and reduced distortion, plus a 0.75" Poly Imide Reflex Horn Tweeter that improves high frequencies. A Conex Damper delivers higher power handling and deeper bass, and the tinsel lead wire and terminals are gold-plated for extra protection.
