The SP-500BT is a Bluetooth speaker introduced by Dolphin Audio. It was made in China. Judging by its appearance, it was probably made by the same factory that manufactured theSoundstream Street Hopper.
It is shaped like a bazooka, and measures 19" long, 9-5/8" tall, and 8-5/8" deep. Dolphin says it weighs 25 lbs, but they must have been smoking something, because it only weighs 9.5 lbs according to our scale.
Anyway, the first thing you notice is the very attractive LED lighting, which uses "glow cords" hidden inside the unit. These lights beat to the music, and can be set to 7 different colors, or simply shut off.
There is also a light on each side of the speaker, and those lights cannot be shut off. And they do not beat to the music, they beat to a fixed pattern, almost like an SOS signal.
Bazooka-shaped speakers like this usually has 2 steel bars between the legs, covered with foam rings that help protect your table from scratches. This is a nice touch
