D-309H Dolby Atmos-Enabled Speaker System


Get the Dolby Atmos® Speakers Your Home Theatre Deserves

Revolutionizing your home theatre for Dolby Atmos® sound is as easy as placing these gorgeously finished D-309H speakers on top of existing front floorstanders or rear surrounds. The 2-Way coaxial speakers use Onkyo’s premium N-OMF diaphragm to reproduce discretely mapped vertical sound elements encoded in next-generation movie soundtracks, so that effects such as helicopters or birdcalls appear to originate from overhead. The woofer’s multi-layered laminate of aramid and cotton fiber provides stiffness to produce low-frequency sound with outstanding clarity, while a high-precision balanced dome tweeter in the center of the cone allows the speaker to deliver both high and low frequency sound from a single point source. Cabinets are constructed from solid wood to reduce resonance and include quality cloth grilles and machined brass speaker terminals. Designed to blend flawlessly with your high-end surround-sound speaker system, these D-309H speakers are a simple and stylish way to unlock the full power of object-based surround sound.
