120+ dB Road King Stereo — Havoc Roar Stereo Bench Test
Bench test of a Havoc Roar Stereo system on an SPL meter, peaking above 121 dB. Unfaired Harley-Davidson Road King and Softail models have no fairing to block wind and exhaust noise at highway speed, so the system needs real output headroom to stay clear.
