Considering that these are skytek, the magnet in the woofer seems pretty big and it’s nice they used a actual compression driver instead of a horn.

[@davidclark3603]

Maybe the idea behind the whole thing, is to provide low cost affordable lightweight sound systems? Truth being known, a lot of people don’t know the difference between good sound and bad sound. What’s more, they don’t care how it works. In fact, they don’t care even if it had rubber bands inside it! Lol! Average Joe public says, “Does it sound loud”? “How much”? To me, it reminds me of something out of a home catalogue and second hand in Cash Converters? If Joe Public is happy with it, who are we to complain? At the end of the day, this was an interesting video. “What’s inside the box”?! We all watched it. And we all enjoyed it. It was good to see inside it. It’s pointless to start grumbling! Peace to you all!

[@randomchannel1712]

Well skytec (qtx is the same brand) is know for ''exceptional'' quality btw their real power output is 35w per speaker and no more

[@Techscrews]

but with PA speakers sensitivity(~97dB/w) they are very loud.

[@randomchannel1712]

yes i know i have tremendous knowledge regarding audio I am just sayng that they lie about their wattage and keep up the good work

[@Techscrews]

of course, almost all brands lie about their wattage. The bigger the brand is, the bigger the lie is about their wattage.

[@BoboButYouCanCallMeTom]

artur take a look at NAD mostly their wattage is higher than advertised plus they sound GREAT.

[@TSilva01]

It's a TDA7377 bridged mode, with 35W power output at 10% of distortion...yeah right. Anyway, you don't get too much power from that small transformer. Real power @ best performance i would say... 10W, not much... Chinese crap.
