Onkyo build and develop some of the most highly regarded AV receivers on the market today, being one of the few brands who focus on sound quality and functionality without compromising on either aspect. The company's range of home-cinema hubs are built into a variety of price points, meaning there's a unit for everyone, and each of these units in each of these price categories tend to win awards and hearts alike.

The THX-certified SKS-HT978 speaker package takes Onkyo's outstanding reputation and technological prowess and integrates it within a compact, aesthetically unobtrusive loudspeaker package. Each speaker has been designed and engineered accurate, room-shaking THX sound. Onkyo and THX technicians have worked together to ensure that movie soundtracks sound as realistic and as dynamically powerful as one would expect. 

The package includes a left, right, and centre front, two rears and a high quality subwoofer. The centre and right/left front speakers feature two A-OMF woofer cones, designed with layers of lightweight polyethylene naphthalene, cotton weave and aramid. This intricate combination means that the drivers are able to move vast amounts of air with a fast and accurate response, ultimately resulting in an outstanding bass and midrange. High-quality soft-dome tweeters mean that this dynamic and punchy sound doesn't overpower the vocal response, and every element of your soundtrack is clear and detailed. The rear units feature the same technology

The active subwoofer outputs a powerful 125 W from its high-capacity cabinet. The cone is 30cm in size, and easily fills a room with liquid-like bass, while the detailed amplification circuit allows this bass to retain an uncompromising level of control.
