Reviews around tone (5.00 of 5)
Gikfun 2" 4Ohm 3W Full Range Audio Speaker Stereo Woofer Loudspeaker for Arduino (Pack of 2pcs) EK1725
-
I was able to get good clear tones from 40 Hz to 10 kHz.
-
For the higher frequencies 10 - 20 kHz I could hear the speaker producing the correct tone, but the amplifier board (a PAM8403) started producing noise that pretty much drowned out the actual tone.
