🔊 Gikfun 2-inch 4-Ohm 3-Watt Full Range Audio Speaker Stereo Woofer Loudspeaker for Arduino (Pack of 2) Review

These little speakers really did the job as a replacement for the speakers that the mice ate in our combine. Easy to replace, good sound. I like the value too.

This is the best sounding speaker I have found in this size. I've spent a lot of money on speakers of this size on various projects and none of them compare to this one in terms of sound quality and volume, even the expensive speakers from Parts Express.

Not sure what they sound like yet. The video shows a 9 volt battery ignition test so I know they will play sound. I'm going to flip n 1/4" MDF for a portable bluetooth build with a 500mah li-ion battery and a 10w bluetooth booster. You could be more careful with the glue they put around d use the external speaker only comes out where the bezel is 10 bucks, that's cool.

Bought for a couple of slot machines. Paired with a $5 3w + 3w amp they sound fantastic. They fit this project perfectly. You won't be shaking the windows of course but you can feel the bass through the table and I prefer to keep it at maybe 60% volume otherwise it gets too loud. They can wheeze a little at maximum volume, but it's still too loud for me.

All my life I've played with speakers and audio equipment. There have been many kicks over the years. There was inspiration. Got her from a bad idea years ago. Tried bluetooth repeater "ICStation DW-CT14". Place them in a cigar box stabilized with CA glue and finished like any wood. Experimenting with all the speakers and amps I have and have experienced is a magical combination. These are the best sounding 2" speakers I have ever seen. After hearing what was in the picture I ordered a few…

Installed these on my Arduino laser tag for sound effects and they are LOUD! I hooked them up to a small amp using an eBoot 6 Pack LM2596 DC-to-DC Buck Converter 3.0-40V to 1.5-35V Power Supply Buck Module, Super Mini PAM8403 5VDC. Pack of 2 and 2 modules Aideepen YX5300 UART Control Serial MP3 Music Player for Arduino/AVR/ARM/PIC. Everything connected, the sound is clear + very loud. In fact, I had to turn the amp down a bit for the recitation to be reasonable.

Install these speakers with Arduino and amplifier board to create a tone generator for my daughter's science project. Tested setting for frequencies from 20 Hz to 20 kHz. I was able to get good clear tones from 40Hz to 10kHz. At higher frequencies of 10-20kHz I could hear the speaker playing the correct tone, but the amplifier board (PAM8403) started making noises that pretty much drowned out the real tone. I wasn't expecting such a small speaker to perform well at low frequencies and the…
