Welcome to our website! As we have the ability to list over one million items on our website (our selection changes all of the time), it is not feasible for a company our size to record and playback the descriptions on every item on our website. However, if you have a disability we are here to help you. Please call our disability services phone line at (262) 242-5599 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability.

Enclosed Tower Coaxial Speaker System, Gloss Black, Sport Grilles (100 W, 4 Ω)

Enclosed in these beautiful, all-fiberglass enclosures are our maximum-performance, M-Series 7.7-inch coaxial tower speakers. Specifically tuned for tower enclosure applications, these coaxial drivers deliver clean, loud audio that can be heard well beyond the boat when mounted up high.

The enclosures feature machined aluminum accents and each includes a very sturdy, spline-based mount, designed to mate with one of our clamp systems (sold separately, and available to fit a wide range of pipe diameters). The wire exits through the center of the mount, staying high and dry, and out of sight. Professional installation is strongly recommended.

For best results, we recommend powering these systems with an amplifier in the 75-150 W per channel range.

Like all JL Audio marine speakers, this system is built to withstand a real saltwater marine environment and deliver years of listening enjoyment.

Sold as a pair.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
