4pcs 4Ohm 5W Full Range Audio Speaker Stereo Woofer Loudspeaker for Arduino Replacement (4pcs)

These are actually very nice, full range speakers. I used these for student projects involving speech, and they sounded great. Obviously, an enclosure can help a lot, but not strictly needed. These were driven by DF Mini Players - worked great with those.

These look cool and have pretty good sound for their size. Since they're 4Ohms, it's good to wire two in series to handle more power. They fit nicely in little Bluetooth speaker projects. Great value as well.

They look really nice, but the sound quality isn't as good as some of the cheaper speakers I have bought on Amazon.

Eh you get what you pay for, as they say. The terminals on two of them were a little beat up and the front plates particularly around the diaphragm had taken a few dings on several of them. My biggest gripe is that they are not actually "full range". I'm guessing they don't go lower than ~150hz which seems to be common for speakers this size, but I got these to build a budget audio test bed and wanted to use these to make a mini sub. Coming out of an amp sub jack, they give off nothing, where a speaker driven by the same amp and rated down to 44hz bumps. "Full range" is supposed to mean the full range of human hearing, which is down to ~20hz and you will not get anywhere close to that here. Haven't had them long, so I can't speak to the longevity, but driven from a good amp, the mid to high frequency is acceptable.

Great deal and sound quality for the price. Will buy again as needed

I bought these for random electronic projects. They are very affordable. They seem to sound pretty good for what they are, but I haven't pushed them very hard. Be aware they are 4-ohm and only handle 5W. They would be very easy to burn out if over driven.

They work and sound ok

These speakers sound great for their size. I'll happily buy them again when I need them.
