Since they're not letting me review this...
I just bought the speakers for my girlfriend needed speakers. I actually own X-320 for 5 years and they shound 10 times better. I Been blasting them many time and the sound is awesome. I bought them for around 100 bucks in 2005.
The sound of the X-140 is really dry. It feels like a cheap youtube video all the time. Add 30$ and buy your self some really good ones.
