ALESIS RA150 2X75W

These amps are designed to provide more power and better performance at a lower overall cost per watt than even Alesis' own RA100 as well as any other competing models. As a result, they can more closely match the power needs of virtually any passive speaker or studio monitor, offering a significantly better fit for an exceptionally wide range of budgets, applications, and customers. And providing a crisp, clean signal for outstanding performance and extended speaker life.


Designed for studio use, each RA Series amp incorporates advanced convection cooling for heat dissipation. The result is long, stable operation unaffected by heat-related complications, without the added distraction and annoyance of fan cooling. And eliminating the danger of losing hard-to-hear details due to noisy amp performance.
