Yamaha HS80M
Designed for nearfield and project-studio applications, the HS80M, like most small active studio monitors, is a two-way, bass-reflex design, bi-amplified via an active crossover (in this case set at 2kHz). The bass port is on the rear panel, which also sports a finned heat sink to cool the power amplifiers. In total there's 120W of amplifier power (75W bass, 45W treble) on board, delivering a 42Hz-20kHz response from the eight-inch bass/mid driver and one-inch domed tweeter. However, the frequency response is measured at -10dB, not -3dB, which is a bit naughty. Like the NS10, the tweeter is protected behind a metal grille, but a new addition is the very shallow waveguide-style baffle that is, presumably, designed to help control the dispersion at or near the crossover point.
