uxcell 3W 4 Ohm Metal Housing Round Magnet Speaker Loudspeaker 2Pcs

Just completed installing my first pair into my DIY speaker which measures 6"X 3" X 2.5" LHW. As a companion to my 8 inch tablet, it is like a perfect marriage of portability and function. With it's small size and incredible sound, it now goes with my everywhere. I am even using it as a speakerphone since the volume and tone is outright great. My creation is powered by the C.J. SHOP® 10PCS Digital DC 5V Amplifier Board Class D 2*3W USB Power Mini PAM8403 Audio Module purchased here at Amazon that is just a perfect match for these speakers. Additionally using a Flyshop 10Pcs Round Button 2 Pin SPST On/Off Rocker Switch AC 125V/10A 250V/6A also bought here on Amazon. All other materials were whatever was lying around my home.

Nice and loud. Took a star because the soldering wasn't quite up to par, but that was easy enough to fix.

I purchased this speaker to repair a Amazon BT4. The speaker fit perfectly and performs as well as if not better than the original. The shipping was quick and free. I would definely purchase from Uxcell again.

Work ok. Lots of crackles. Fine for a small project with a few sounds.

Driving from an Adafruit PAM8302 mono amp. Good good clarity and very low distortion at full volume. Not incredible quality, but very good value.

Bad sound, save your money.

Pay attention, these are about 1 1/2" in diameter so do not expect large speakers. But the quality is good and sound fine for such a small low cost speaker. I use them with Raspberry Pi & Arduino projects (with a tiny 3w Adafruit dac amplifier). You will need to solder leads to them as they do not have clips. And obviously, you need to add your own amplifier.

Works as described, will start burning up if you keep heat on the pads for too long. The copper wiring is also extremely fragile. These speakers work great and are really mini subwoofers!
