Onkyo SKS-HT870 review


Onkyo is known for having speaker expertise, even though it's not primarily a speaker company. That's because of Onkyo's success selling home-theater-in-a-box systems (HTIBs), which combine a speaker system and an AV receiver in a single box, taking...

A 7.1 surround sound speaker system; excellent sound quality; subwoofer blends well with speakers; can fill relatively large rooms; relatively inexpensive, especially for a 7.1 system.

Relatively large speakers; boxy design; wood finish lacks refinement compared with other options; spring clip connectors.

The Onkyo SKS-HT870 speaker package offers up tons of performance for the price, but it's not the most stylish speaker system.

Onkyo SKS-HT870 7.1 Speaker System

Product Specifications

For maximum audio impact, your multichannel Onkyo receiver should be accompanied by a full-blooded surround-sound speaker set. Fitting the bill is the SKS-HT870, a 7.1-channel system that injects power and vitality into all your movies, games, and music. The highlight, both visually and aurally, is a pair of dual-drive, floor-standing tallboy front speakers rated conservatively at 130 W. In concert with the two-way center and full-range surround and surround-back speakers - each also rated 130 W - they deliver stunningly detailed high- and mid-range frequencies. Meanwhile, at the bottom end, a superbly calibrated 290 W subwoofer adds visceral heft to bass notes and low frequency effects.
