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

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 😅

I used one with an arduino, i wanted something with a bit better sound than the small cheaper ones and these did not disappoint at all, would definitely buy again

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 :)

The speakers worked well for the purpose that I intended them for. No obvious sound quality problems. Note though that the impedance is 4 Ohms, which may be a little low for some sound players.

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.

Ideal for small ham projects .Sounds great fitted to a project box to improve aquatic’s.

These speakers were too big for me but the looked ok. I’ve returned then a couple of weeks ago but still waiting for a refund.

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.
