Here’s a soundport I added to a clients Yamaha classical. With the door off the player receives a boost in volume and hears or experiences more of the guitars voice that is directed out the main sound hole towards an audience. The door can also be left on to keep the sound projection as it was which can be helpful when playing in a group and listening for everyones levels. Soundports are not a gimmick, they can definitely enhance the players experience, almost like a natural monitor. As with many advancements they were developed by hand builders and are now showing up in a few commercial instruments, along with arm bevels!
