Sound like in the cinema – this is what the legendary quality seal THX stands for. The SKS-HT978THX speaker system from Onkyo is certified according to this standard. Inspired by a Hi-Fi classic from the 1970s, each speaker has been constructed, optimized, and independently tested by technicians from Onkyo and THX with the utmost care. The result: an exhilarating sound experience that perfectly reproduces the full dynamic range of a film soundtrack. The solid MDF enclosures are equipped with one (surround speaker) or two (front left/right and center) A-OMF membranes. These membranes contain layers of lightweight polyethylene naphthalate, cotton fabric, and aramid, providing exceptional speed and precision, while high-quality 2.5 cm soft dome tweeters reproduce frequencies up to 45 kHz clearly and precisely. Because the speakers are sealed, they can be placed almost anywhere without compromising the clarity and impact of the bass. In the case of the surround speakers, wall mounting is even possible. Completing the 5.1-channel speaker package is a 125-watt subwoofer with a powerful enclosure and a forward-firing 30 cm cone that fills your home with rich bass sounds. This complete system, with its elegant surface finish, is a true heavyweight – and the fastest and most affordable way for you to experience genuine THX multiplex sound.
