Speaker Cleaner & Low-End Bass Test

Test bass response after cleaning your speaker. Verify woofer cone excursion from 40 Hz to 120 Hz without distortion.

Start audio tests at low volume; stop for distortion. Tones cannot guarantee removal of water or repair internal damage. Do not charge a wet device.

Low frequencies demand large cone movement. If even microscopic droplets remain on the woofer cone, heavy bass notes will buzz or flutter.
