My buddies and I were at a lakehouse a few weeks ago and one of my friends had this speaker. I was blown away at how clean and crisp it was as far as the bass and the sound quality overall. I'm aware that this has to be plugged into an outlet in order to play, correct? Also, the other thing that I'm making sure of is that it's specifically the "stanmore" speaker that I'm looking at? Is that the correct one that is a plugin and has a hell of a lot of sounds to it? I'm looking at getting the all black or the normal black one.
