This is a separate preamp and powered speaker I put together several years ago. The Stereo Steel preamp is in one enclosure (not sure of the manufacturer) and the speaker and amp are in a Rick Johnson enclosure. All of the power cords and connections are self contained, and it sets up very quickly. It has an Eminence 15in neo speaker. The amplifier was made by Evans and fits neatly in the speaker enclosure. It is a 200w solid state amplifier. The powered speaker weighs 39lbs and the Stereo Steel preamp weighs 12 lbs.
