Elegant in its simplicity
Crutchfield Customer Review (What's this?)
Very basic tones, nothing fancy, but expertly produced and recorded. This is one installation tool i couldn't part with. Tracks 15-99 are sine waves with the track number corresponding to frequency. Helpful for tracking down rattles, evaluating frequency response, optimizing subwoofer placement, setting gain, setting crossovers, scaring the dog... does all this and more!
