If you’re serious about experiencing THX-certified cinema reference surround-sound in your entertainment space, look no further than the SKS-HT978THX package from Onkyo. Born of a legendary 70-year Hi-Fi heritage, each speaker has been painstakingly designed, tuned, and independently tested by Onkyo and THX technicians to ensure film soundtracks explode with rich layers of detail and immersive wide-spectrum dynamics. Solid MDF cabinets are fitted with either one (surrounds) or two (front LR and center) A-OMF woofer diaphragms that use layers of lightweight polyethylene naphthalate, cotton weave, and aramid to achieve exceptional speed and accuracy, while high-quality 2.5 cm soft-dome tweeters cleanly extend treble out to 45 kHz. And because the speakers are sealed, you can position them almost anywhere-it’s even possible to wall-mount the surrounds—without compromising bass power or clarity. Rounding out this 5.1-channel speaker package is a 125 W powered subwoofer, it’s high-capacity cabinet and 30 cm front-firing cone filling rooms with wall-shaking bass impact. Forget lightweight toys-this beautifully finished full-scale system is the most convenient and affordable route to THX multiplex sound.
