Review: Very good sound quality - Used to enhance the chime sounds for a miniature grandfather clock. It replaced the original small 25-cent-piece size speaker that had a very tinny sound. The sound is much better now. Edit, lol, I should probably have used a piece of video that had the chime sound on it. duh. lol I will update this review with another video with sound as soon as I can.
Review: Piccoli altoparlanto con cassa - Vanno bene dove servono piccoli altoparlanti (0.5W circa). Hanno il vantaggio di avere una loro cassettina in plastica, questo facilita il montaggio e l'uso. Sarebbe ancora meglio se avessero una protezione sul davanti (retina, tessuto o simile).

Vanno bene dove servono piccoli altoparlanti (0.5W circa). Hanno il vantaggio di avere una loro cassettina in plastica, questo facilita il montaggio e l'uso. Sarebbe ancora meglio se avessero una protezione sul davanti (retina, tessuto o simile).
