Now to the sound:
... Hmm clear compared to my Heco tower speaker .. yes we do not need to talk about it.
So the boxes are in my opinion good geeingnet for Electronic Music.
The bass is super, the tweeters are not bad, clearly no match for Heco, JBL, Quadral from her sound, but they are fine!
For Rock / Punk / Metal they sound somewhat dull trozdem plenty of power even at higher volumes.
I hear a lot of Techno and I found the sound of Hyundai's best.
I made a little video and run a few different styles of music.
(The vibrate put on some originate from my windows and doors: D The boxes have a lot of power and make no hub noises!)
Conclusion:
Buys the parts! You can do really nothing wrong for the price!
