Gikfun 4Ohm 5W Full Range Audio Speaker Stereo Woofer Loudspeaker for Arduino Replacement (Pack of 2pcs) EK1949

These speakers look solid and good, unfortunately I have not tested them.

I made an Ammo Box sound system w/ these speakers, an Icstation 2x5w BT 5.0 amp board, and a 3.7V 2300mAh 505085 Lipo Battery. I added an illuminated on/off switch and a external usb power/charging port. I am really impressed with the bass response from these little 2" speakers, and they handle all the power the amp puts out clean. It holds it's own (w/ more bass) against a larger 2x10w Ammo Box w/ 4" Pyle marine speakers I made last year. Parts are ordered to make another w/ the addition of 3" passive radiators,1/2" dome tweeters XO'd at 6 kHz, a 2x10w amp, and a larger box to hold it all.

Good for experimenting , hobbies , but not for fidelity in low frequency rage .

Decent quality for a audio output most suitable for voice as an assistant, not so much for music and bass.Small enough for DIY arduino/raspberry pi projects.

Came packaged well, and is fairly well built for the price. Also, sound is very decent. I used this in a portable 2-way radio project (hammocan), and it worked perfectly and sounds much better than the speaker built in to the radio unit I used for the project.

These work much better than I expected. For the size the sound is amazing. They do need to be mounted in an enclosure of some kind but when enclosed they work well.

We build cosplay props that use sound and lighting and tried these speakers out. To our surprise they worked great. With the right implementation (enclosure and porting) these things sound surprising good. Good bass and detail with plenty of volume for their size. I would use these again for sure!

Well, I bought a couple more sets so I can make a pair of desk top speakers.These seem to handle the 5w pretty well. Best not to push them too hard. I plan on linking them in triple series.Though these produce pretty nice sound quality, one should not expect a room filling experience.These will be great for listening to audio books!
