The PRO60G3, designed for the Malibu G3 Tower, when used in conjunction with the 3G-SHELF adapter mount. The PRO60G3 is a Wakeboard tower speaker designed for those who crave the award winning sound of the PRO80 but need something in a smaller, more compact size. Utilizing the same professional grade concepts and acoustical engineering, we developed a 6.5" version of our PRO-Axial™ driver. the PRO60 G3 is a single 6.5" Wet Sounds™ EFG™ (Epoxy Fiberglass) driver and a concentrically mounted Wet Sounds™ HLCD (Horn Loaded Compression Driver). With the PRO60G3, you can finally have big sound in a small package.
