If run on a flat EQ, they are a bit too heavy on bass and treble and lacking the midrange a bit. Assembly was a breeze and the instructions were simple and easy to follow. My kiddos are usually running around screaming and laughing, the furnace is running (office is in the basement), and I forget to turn off the sound on my phone. The speaker really shines playing more modern electronic music, hip hop, edm. These are our first electric bikes (some may call these scooters). I ordered the beige color. I love this fabric. UPDATE, BUILD QUALITY:Well, Ill be damned, its been exactly a year since I wrote this. Fits the hole and keeps the shelf up. One involved more sitting and one I was walking around for a day.
