Open to All Attendees!
Frank Urban will explain the unknown problems (like phase shift and time delay) that are inherent in all powered subwoofers and will show how to eliminate them.
Frank studied acoustics at Eastern Illinois University and physics at Roosevelt University. He was a member of the sound crew for Lollapalooza and Taste of Chicago. Now an engineer at US Soundlabs.
Two lucky attendees will win our SW2 - signal conditioner for subwoofers!
