A tower provides additional real estate to expand your audio arsenal. When it comes to hanging speakers, options abound, but they'll likely fall into two categories—soundbars or self-contained tower speakers. The biggest advantage of soundbars is space. They cluster together multiple smaller speakers, so they don't extend as far down as dedicated tower speakers. However, what you save in space you'll give up in the level of the audio. "For wakeboarding in particular, if you're tying to get sound 60, 70, 80 feet back to someone behind the boat, those soundbars aren't going to be able to get as loud as larger hanging speakers," Brumbaugh says.
