This is a thread where you get to bash talk any speaker that you have heard that just makes you question the sanity of who ever designed them.
There is a similar thread for the worst headphones you have ever heard, so I decided to make a sister thread.
I will start.
Monitor Audio PL300. At about 1500 bucks, I think this is one of the worst speakers ever made. My friend and I listened to them with a decent amplifier and CD player, but there was simply no bass and the mids were ridiculously thin. We listened to diana krall and we honestly thought we put in a different disk because all the body of her voice was just out the window.
