Hahn has a long relationship with Coors Field, home of the Colorado Rockies. Neil Hahn was the project manager for the Audio Contractor on the stadium for the original Public Address System installation. Coors Field is one of the only stereo stadiums in the world with every other speaker cabinet on a separate feed for fire redundancy. Hahn has provided upgrades and designs for the Public Address System almost 20 years. GO Rockies!
