Our client has a large self-storage unit for his collection of classic cars and wanted to add a top-of-the-line 2-channel audiophile environment to the space. The storage space is approximately the size of a small airplane hangar, and is located next to the Monterey Regional airport that services major 737 carriers. As you can imagine, jet noise and audiophile music could have been a combustible combination. PMI Engineering was hired to design a complete sound-proofed room, and MSR supplied specialty sound isolation materials along with a Dimension4 Symphony acoustical tuning system. The end result was music to the client's ears! For more info on MSR's innovative acoustical solutions, please visit our website .
