Onkyo are renowned for developing some of the most superlative home cinema products on the market today, and continue to uphold that prestigious reputation with releases like the SKS-HT728 5.1 surround sound system. This system has been designed to breath a new essence of life and vitality into all of your favourite films, TV shows and video games. 

An aesthetically pleasing design, the SKS-HT728 speakers are compact in stature, resulting in a rather discrete visual profile. The sound is anything but compact however, with the floorstanding fronts rated at 130w bringing an exemplary level of power and detail. When used in conjunction with the matching two-way center channel and full-range surround speakers (which have also been rated at 130w), the result is truly stunning. A meticulously detailed high and mid-range frequency response is achieved.

Combine outstanding high/midrange sound with the precisely calibrated 290w subwoofer and every aspect of the sound spectrum is catered for and handled with the same level of unbeatable skill and finesse one would expect from any audio/visual product designed and engineered by Onkyo. 

All the speakers in the system feature an impedance of 6 ohms, and colour-coded speaker terminals/cable. All the speakers involved in the system are wall mountable, except for the floorstanding front units.
