MakerHawk2pcs Mini Speaker - 3W 8 Full-Range Portable Advertising Speaker Connector (3.3V - 5V)

Works well and sounds alright. Nice little test speaker for DIY projects before committing to a nicer one.

My goodness these things are incredibly loud!

I paired this with an M5Stack Atom Lite ESP32 and a MAX98357 DAC/amplifier and set the volume at +12dB by shorting the gain pin to ground. The Atom is running ESPHome. I am driving it with the Piper TTS add-on to Home Assistant. It works great - volume is at a standard voice level and the voice is very clear. Overall it sounds better/clearer than a cell call on speaker with a volume that is similar. Below is the yaml I'm using on the Atom, if that is helpful. Of course your chosen pins may vary. Total cost, $22.50, but I'm using the same Atom for two other purposes - a relay and a smoke detector, so effectively this is very cheap.i2s_audio:i2s_lrclk_pin: GPIO23i2s_bclk_pin: GPIO19media_player:- platform: i2s_audioname: ESPHome Voice Announcementsdac_type: externali2s_dout_pin: GPIO22mode: mono

todo perfecto

I used one with a 2 watt amplifier for a ship's horn on my model Navy ship. Plenty of volume. I did not play music or voice so I cant say to that quality but the horn sounds great.

I bought a variety of compact 8 ohm speakers to evaluate for use with a horn-bell sound module in a model train engine. This one was the smallest and one of the least expensive speakers I evaluated. It certainly didn't look like a traditional speaker. Frankly I was expecting this speaker to perform the worst. But in tests, the speaker performed surprisingly excellent. It surpassed my expectations. A further advantage of the speaker is that it is encased and easy to mount.

Positive transaction, nice item, recommend seller!

I was simply looking for cheap, small, 8-ohm type speakers I can use to output sound when I need to from circuits I build. I thought the solid square structure of these is a nice step up from simply having a speaker consisting of the cone and magnet on the back side.
