ACEIRMC4pcs 4Ohm 5W Full Range Audio Speaker Stereo Woofer Loudspeaker for Arduino Replacement (4pcs)

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.

Obviously you want to order speaker components from Parts Express or something if you're looking for true high quality sound. But for a four pack of speakers, you could certainly do worse. Highly recommended, especially if you're just experimenting with little DIY audio circuits.

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

They work and sound ok

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

They have separated from the cone already in under 2 months.

Bought these to fix a Bluetooth speaker but they didn't fit, have run sound through them and it's nice and clear. Plan to set them up in my truck next time I work on it's sound system.
