From Mesa Boogie:

“By itself or as a companion to a 1×12 or another 1×15 cabinet, our most popular single speaker format is the 1×15 Ultra-Lite. A little larger footprint (than the 1×12) accommodates the needed internal volume to match the 15 Full Range driver and create this, warm, huge sounding compact cabinet that shines for everything form old-school Blues and R&B to scooped modern Slap and tight, picked Rock styles. Our sweet High Frequency Driver ensures the detail remains intact and imparts an adjustable Hi-Fi character to the sound. By itself, or as a foundation for further coloring with 10s or 12s, the 1×15 anchors the Subway Cabinet Line with its flexibility, warm and accurate performance across the full range, and ease of transport. You cant go wrong with a classic and this great sounding, carry-friendly Cabinet has all it takes to earn that status.”

Very Good condition, 8 ohms, 400 watts, There is a small piece of one of the plastic corners missing.
