JBL Marine Stage 8 – 8" (20 cm) 2-Way Marine Coaxial Speakers – White (Pair)

Built for boats and the outdoors, JBL Marine Stage 8 speakers combine rugged construction with the lively JBL sound you expect. A polypropylene woofer and balanced-dome tweeter provide punchy bass and smooth highs, while the sealed motor structure, UV-resistant cast-polymer basket, rubber surround, and stainless mounting hardware stand up to sun, salt, and washdowns. At 90 dB sensitivity and 125 W RMS handling, they play loud and clean from a marine head unit or external amp. Pre-attached white grilles keep the look tidy on deck.
