Gikfun 4Ohm 40mm Diameter 3W Full Range Audio Speaker Stereo Woofer Loudspeaker for Arduino (Pack of 2pcs) EK1794

Ordered this to replace a damaged speaker in what was an expensive, brand named, Bluetooth receiver. The specs on the speaker said it was 40mm, okay, no problem. I ordered these 2 40mm speakers, only needed 1, and when I went to swap them out, the new one was just the right diameter to fall thru the speaker hole on the unit. I'm not one to give up easily, so I got some tools and made some modifications, and with the help of some gorilla glue, was able to retrofit the new speaker into the Klein Bluetooth unit. So before you order anything, be sure to measure whatever it is you're replacing, and compare it to the new item, don't just assume like I did. You know what they say about making assumptions, you end up making an ass of u&me. Since the unit didn't work when I got it, I'm not able to give a sound quality comparison between the new speaker and the original speaker that came with it, but the new one sound decent.

Refreshed the JBL Creature with this. Being picky, but I feel like the mids aren’t pushed as much with these compared to stock. I know these are tweeters, but since the creature only has a sub + tweeters, kind of have to rely on these to get the mids out. Regardless, decent dynamic range for the size and the creature sounds good all things considered. If you’re planning on doing this, you’re gonna have to trim the plastic inside the casings. Honestly, you can not use the plastic inner casing if you want.

It's crazy to think what 5watts can do compared to this 3watts. Sounds great, but has no bass like a cheap speaker you'd by for 10 to 20 bucks. Overall. It's worth the price for what it is. Would recommend if you need some tweets. This will hold for now til I get the 5 watts.

Pretty good speakers. Volume can get pretty good but the louder you go the quality starts dropping.

I soldered 20 gauge wire and attached Dupont pins to each speaker. They worked great with the DFPlayer and the MP3 TF card U drive player. Neither player was able to drive them into distortion levels. They handled the volume right up to the limit of the breadboard power supply (the kind that snaps into the top and bottom rails of a breadboard). The amplifiers on both the DFPlayer and MP3 Player want more power than that supply can provide. But no problem for the speakers.

Fits perfect on JBL flip 2 just have to fabricate a hold down bracket for speaker. Speakers sounds great!

Low volumen, no bass at all, low quality... If used with ppl that doesnt have ears may be worthy then not good at all for me.

I like these speakers. I bought them as a replacement of "tweeters" speakers on the car front doors situated by the side mirrors. Before purchasing these, I bought boss tweeters for about $10 but those were so crisp they hurt my ear. These on the other hand are PERFECT! They're a very good balance between mid range and tweeters. The sound comes out clear, loud enough for a car audio and crisp enough as well. Soldered them to existing wiring and voila! The price is unbeatable. Highly recommend!

I bought these to use in a custom DIY smart speaker project, and they work absolutely brilliantly. For such compact little units, they pack a really punchy and clear sound that’s perfect for small-scale audio setups. The build quality is solid, they are super easy to wire up and integrate into a custom housing, and they handle the power output without any distortion. Whether you're working with an Arduino or building your own custom audio rig, these are an excellent, budget-friendly choice that delivers exactly what you need.

Einfach Super

Surprenant

Llego una golpeada

Great sound I printed a box for it sounds great
