This week, host Jorden Guth continues his conversation with Paul Barton, founder of PSB Speakers. If you haven’t listened to season 3, episode 1 yet, do check that out first! In this second half of their conversation, the two discuss how the research at NRC contributed to the evolution of PSB speakers. Along the way, Paul gives the most cogent explanation ever of baffle diffraction and waveguides, and discusses how different driver materials affect the performance of a speaker.
