Eden merged the popular WT550 amplifier system with their D112XLT enclosure. In doing so, they have redefined the standard for small professional bass guitar combo systems.  The DC112XLT has amazing tone quality and a massive output for such a small unit.  With 330 watts at 4 ohms, the DC112XLT will outperform any single 12" combo you can throw at it.  It has a frequency response of 32Hz - 14KHz with lots of headroom and minimal distortion.
