Sound like in the cinema - the legendary THX seal of quality stands for this claim. The SKS-HT978THX speaker system from Onkyo is certified to this standard. Inspired by a hi-fi classic from the 70s, each speaker has been carefully designed, optimized and independently tested by Onkyo and THX technicians. The result: an exhilarating sound experience that perfectly reproduces the full dynamic range of a film soundtrack. The solid MDF cabinets are equipped with one (surround speaker) or two (front, LR and centre) A-OMF diaphragms. These contain layers of lightweight polyethylene naphthalate, cotton fabric and aramid and are characterized by exceptional speed and precision, while high-quality 2.5 cm soft dome tweeters reproduce frequencies up to 45 kHz clearly and concisely. Because the speakers are closed, they can be placed almost anywhere without affecting the clarity and power of the bass. In the case of surround speakers, wall mounting is even possible. The 5.1-channel speaker package is rounded off by a 125-watt subwoofer with a powerful cabinet and a 30-cm cone radiating to the front, which fills your home with rich bass sounds. This complete system with an elegant surface finish is a real heavyweight - and for you the fastest and most affordable way to real THX multiplex sound.
