Online Tone Generator
The 60 second online subwoofer test. It's free, simple and no sign up required. How low can you go?
This page contains a low frequency sweep and a series of tones for testing the response of subwoofers. Click the play button below to begin the test. You will hear a sine wave start at 150Hz and gradually decrease to 1Hz over the course of 60 seconds. We have also provided a series of continuous tones (compatible with Firefox 4 or later) to help you get the most out of your subwoofers. How well do your subs perform? Let us know in the comments section at the bottom of the page.
