Our 1000 watt D410XST features a deeper,stronger low end than the XLT, and a more open, transparent midrange definition and exceptionally flat studio-like response along with reduced size and weight. The tone is wonderful, well-balanced with a smooth, effortless quality usually reserved for the studio. If you like high-definition and low distortion coupled with a big sound, this is well worth the auditioning. Massive internal bracing and optimum bracing make for extremely tight lows.
