All MAG amplifiers have extension speaker outputs and are loaded with Ashdown BlueLine speakers for exceptional attack, clarity and low-end performance. Protection is provided by tough black carpet covering and new steel grilles, while the amplifier chassis is constructed from light yet strong, heat-dissipating magnesium alloy for ?roadie-free? portability. And, of course, the famous Ashdown VU meter remains central to the cool look of these great, value for money bass amplifiers.
