In this episode of "DIY or Buy", we will be having a closer look at directional speakers. The usage of such speaker is "fairly" new and quite interesting. As the name would suggest, they can playback audio in a very directional straight beam. So how does this sound? How does it work? And why is it so expensive and can we maybe create a cheaper DIY version? Let's find out!
