This bundle includes a pair of 12KMTES Black marine wake tower enclosures and two Silver Kicker KM 6.5″ Marine OEM Replacement packaged speakers Spectacular highs and midrange sounds coupled with the simplest of speaker installations provide full-range audio specifically for a marine environment. UV treatments on the coaxials’ injection-molded cones, Santoprene surrounds, baskets and grilles help all models maintain in marine environments. These speakers can endure almost any weather conditions with splash-and-spray-resisting sealed motors, cones and locking terminal covers. Speaker hardware is forged from rustproof, 316L stainless-steel. Speakers are also pre-installed with stainless-steel mounting screws to keep them rust free for years to come. The enclosures were designed with a nine-degree axis rotation in either direction, allowing the speaker cans to be aimed in the most desirable location to deliver maximum sound quality. Includes polyfill, mounting hardware, aluminum tower-pipe clamps (2-5/8-inch), and three sizes of mounting adapters for the most popular pipe diameters (2-1/4, 2-3/8, 2-1/2). KICKER also offers the KMTAP Tower Enclosure Adapter Pack (sold separately) for fitting several other pipe sizes. Fits mounting tube sizes 2-1/4, 2-3/8, 2-1/2, 2-5/8 without the need for KMTAP. KMTAP adapter sizes include 1-5/8″, 1-3/4″, 1-7/8″, 2″ (Pair) and must be purchased separately.
