Bass Test Sinus Sweep 15-95 Hz low frequency response subwoofer test tone sine wave 

My go3 almost blasted!

Sony dm4 headphones picked up 15-95. Now ima have to try this in my car and see how low my sub can do.

I tried this on my skullcandy crushers... it was nice

60 - 63 is my fav

Sounds good on a Logitech speaker

Almost no sound on my TV speakers. Only minor hump from 80+ hz onward. LOL

Almost blew my speaker caps off
