Awesome sound quality, accueq setting isn’t very accurate but a good starting point, highly highly highly recommend getting a 12” powered sub as well as using the provided 8” as the 8 misses lower bass notes the 12 can hit easily

No issues with the sub, has more than enough power to shake the entire house

Note here that the white LED power indicator is lit up

The subwoofer audio suddenly turns off even at regular volume level (not even at 50% of volume dial of the subwoofer and the LED power indicator is ON

**If anyone is looking to get this set up for gaming or loud music playing with heavy bass (aka hip-hop & trap music), I recommend getting a 3rd-party powered subwoofer because although the Harmon Kardon satellite speakers hit the mids & highs really well, the subwoofer could most definitely use more power in order to properly hit those lower frequency notes
