Any boat is a harsh environment for audio equipment, but a pontoon throws even more challenges at a sound system. For starters, pontoons are relatively exposed. There’s really no place for speakers to be sheltered from the elements, as nooks, crannies, and overhangs are hard to find. That open atmosphere and potential for an abundance of passengers also makes it a challenge to achieve true, quality sound, and deliver it to passengers throughout the boat. There’s no enclosure to help with acoustics, so plenty of power is necessary to achieve ample volume and sound quality. All those bodies will also absorb sound.
