The AER Compact XL: the top of the Compacts. The AER Compact XL carries on the Compact tradition as a highly portable 2 channel acoustic amp. Yet the XL sports a muscular power section pushing a nominal 120 watts through a state-of-the-art 2-way speaker system with a 8" (200 mm) cast frame low-midrange + a separate 1" (25 mm) dome tweeter. When you seek the utmost acoustic accuracy, plenty of headroom, and phantom power capabilities, the AER Compact XL is a serious musical partner.
