The Yamaha HS5 is a compact powered studio monitor for the home studio, or even as a second reference in a professional control room. Calling upon the styling and function of the ubiquitous NS-10M monitors made popular in the 1980s, the HS5 adds built in bi-amplification for 70W of total power pushing a 5" woofer and a 1" tweeter. The sound is true and unflattering -- if it sounds good on these speakers, it's because it sounds good everywhere.
