Each speaker has an 18 watt amp for the woofer and 14 watt amp for the tweeter, total wattage per speaker would be 32 watts for a total of 64 watts for the pair.

Thanks for your interest in our products. **Q: Can these connect to my laptop via a standard 3.5mm headphone jack?** A: Then WHY doesn’t Microlab state this upfront???? Too hard to ad a single sentence to the description? Why just say AUX?? That just means auxiliary!!! As in, external. My DESKTOP computer does not even have bluetooth, and its a 2 yr old dual processor 32g ram Lenovo d30 workstation!!! But, like EVERY desktop on the market, going back 30 years, it DOES have a standard 3.5” audio out or line-out, in addition to 3.5” headphone out!! So does my laptop; but I nor many of your possible customers, would use this at home/office, with my desktop!! This is a growing trend with ‘puter interface et al descriptions; let the 80 yr. old office janitor write them instead of a trained expert... **Q: These speakers are powered. how? battery? ac? looking for 120 vac / 60 hz (us). thanks!** A: These speakers are AC 120 Volt powered, please let me know if you have any additional questions.
