Harman kardon onyx 3 has four drivers and two passive radiator, one radiator on the back also. with two tweeters and two woofers, and power of 15 Watts total 60. when we are only using a wired connection. Wireless, its half. that is 30 watts
One disadvantage tha harman kardon onyx studio 3 The battery life here is just bad. And when we are listening loud music. both Onyx 2 and 3’s five-hour battery lives. but this is obvious that when we play music at louder volumes, battery runs way faster, When we see the size of speaker we can understand that it can not take heavy battery and that is fine So we have to frequently recharge these speakers
