Rockville is proud to introduce our all new line of aluminum wakeboard cans. The MAC65B comes in pairs and includes our rugged universal aluminum clamp for easy installation to any wakeboard tower pole measuring from 2" to 2.5" diameter. Six precision molded high impact rubber inserts guarantee fitment on towers from 2" to 2.5". Our clamp inserts are precision-fitted to sit perfectly inside the metal clamps. The speaker terminals are safely enclosed inside the waterproof speaker canister.
***Please note if you need an insert to accommodate a 1.75" diameter tube please let us know and we will send one out to you free of charge!

These awesome pods are built of super strong aircraft grade 6061 aluminum. The MAC65B features a black powder-coat finish which offers unparalleled resistance to chipping, scratching, and fading. They are fully marinized which means they'll withstand the elements on the water. These cans are 100 % waterproof. What makes our technology the best on the market is that our pods are internally wired! This means the terminals are inside the pod and the wires are fed through pre-drilled holes on the pod and clamp. Simply align the wire opening with the hole on your tower and you are done! No exposed wires or terminals! Aluminum cans will last forever!

The sound quality of these are phenomenal! These are the perfect amount of air space to give you the perfect sound quality with the leading marine speakers on the market from brands like Kicker, Rockford Fosgate, etc. Our high efficiency design means more audio output from the same speakers! This means you get louder, cleaner sound with less distortion using our wakeboard enclosures than with other brands.
