2" 4Ohm 3W Full Range Audio Speaker Stereo Woofer Loudspeaker for Arduino Diy (Pack of 2pcs) EK1725U

I purchased these speakers for a weekend project with my 6 year old son, who wanted to build his own "Alexa" (Echo Dot) from scratch. Using some scrap wood from the garage, we built a custom enclosure, mounted a mini audio amplifier on top, and wired everything up. Here is why these speakers earned five stars: Surprising Performance: For the size and price, the sound quality is impressive. They are significantly louder and clearer than I expected, easily filling the room. Easy to Install: The mounting process was straightforward, making them ideal for a DIY "garage build." Great Educational Value: This was a fantastic way to teach my son about electronics and assembly. He is absolutely thrilled with the result and is already planning his next build. Excellent Value: Given how well they perform, I would happily purchase these again for future audio projects. The Verdict: If you are looking for reliable speakers for a hobby project or a STEM activity with your kids, these are a perfect choice and great value for money! Seeing my son’s excitement when they first powered on was worth every penny!

Retrofitted to my Volkswagen Caravelle T5 which front dash speakers had perished. Not many people know that there is a little speaker (this) as well as a tweeter. After much cutting and melting the old speaker out of the old mount I managed to shave the metal square edges off to get it to fit. Not the prettiest but fits under the speaker grille. Good voice sound quality, bit fuzzy at high volume though.

A decent set of small speakers for little hobby work. Don't get me wrong, these won't give audio good enough to entertain Wembley Stadium, but for little hobbies they work well. I've got these in a little bar top arcade cabinet and they give me a decent enough audio. Don't sound tinnie but do give a little rattle if you turn up the bass. I run these from a small amp so I can adjust the bass and treble. For something as small as these I'd be fooling myself to expect anything professional. These little speakers do exactly what I want. Perfect for my bar top arcade.

The advertisement mentions "Arduino", but it's difficult to get a decent sound level from these speakers with an amplifier that is powered by a Arduino/Raspberry Pi power supply. There just isn't enough voltage swing available. At the sort of volume levels that can be achieved, the speakers sound OK, but they're only any use in a quiet room. That's not a fault of the speakers, but of the way they're advertised. In my experience, the old-fashioned, small, paper-coned speakers generate more sound with a lower drive voltage, and might be more suitable for a very-low-voltage application. The speakers themselves seem robust, and they look smart when installed in a piece of equipment. At £5 each I don't think they're great value for money, but I guess it's OK.

Good speakers for DIY projects, very affordable, compact and powerfull enough for outdoor use. I have made a Bluetooth portable speaker out of it, and am very pleased with the sound quality and the end result. On the downside It doesn't have a havy bass line, but that can be adjusted in EQ for those wobly base line lovers :)

I was amazed of the quality and how well centered the speakers are. Will buy again!

Bought to replace some rubbish drive units. Unfortunately, my mistake, they didn't fit. May try them on another project. They look very good, nice surround, quite compliant. High hopes.

Picked these up for a home automation project and was pleasantly surprised at how good they sound. Maybe even a bit to much; feel bad for using them for the silly project I had them in mind for now 😅

Non mi aspettavo dei bassi così profondi da due piccoli altoparlanti del genere: OTTIMI

Habe eigentlich nicht viel von den Lautsprechern erwartet, war allerdings etwas verwundert über den doch recht hoch angesetzten Preis, auf anderen Plattformen liegt der Preis für solche Lautsprecher bei unter einem Euro das paar... jedoch mit sehr langer Lieferzeit. Die Effizienz und Klangqualität der Lautsprecher ist wirklich sehr gut. In einem relativ kleinen 3D gedrucktem Multichamber infinitywavedeflector Gehäuse klingt alles was diese Lautsprecher ausspucken absolut klar, räumlich und akkurat, die Lautstärke ist erstaunlich und Pegelfestigkeit ist bis ~72% Peak gegeben. In Anbetracht dieser Tatsache muss man sich schon Fragen, was sämtliche Bluetooth Lautsprecher Hersteller für einen billigen Ramsch in ihren völlig überteuerten Knarzkisten verbauen... jedoch liegt der Fokus dort immer auf völlig deplazierten Bass.
