Dave Anderson and Mike Heilemann win the People’s Choice Award at CEIS Showcase 2016!
Acrylic wall speakers in the lab, probably made in 2016.
Acrylic panels with exciter arrays optimally matched for the lowest panel modes. Acrylic may be heavy but it sounds particularly good due to the high internal damping of the material. These were meant to be roughly TV or monitor-sized. Made in 2016.
Test equipment and setup for various speakers. On the right is a guitar amplifier prototype with 6 exciters and a 50W amplifier.
Small (iPad-sized) flat panel loudspeaker with 24 exciters. The aluminum panel sounds particularly terrible due to the high resonant frequencies of the clamped BC modes. Made in 2015 for an AES conference paper.
Large red plexiglas panel with custom amplifier array and 15 exciters. Made in 2015.
Gorilla Glass loudspeaker with 15 exciters and an array of amplifiers for active control. Very primitive – probably made in 2014 or 2015.
Gorilla Glass panel made with 32 small exciters – probably in 2014. Originally designed for measuring individual modal resonances and Q factors.
