To conduct our listening tests, we paired the SKS-HT870 with our Denon AVR-3808CI reference AV receiver. The very first thing we noticed about the SKS-HT870's sound was that it didn't do anything badly. We rarely say that about budget-priced speaker packages, which either have embarrassingly awful subwoofers, or overly aggressive tweeters, or both.
The SKS-HT870 sounds right, and even though the surround speakers lack tweeters, timbre was remarkably consistent through all seven speakers. The subwoofer is so well matched to the speakers we didn't really think about the sub much, and that's always a good sign.
We were so confident about the SKS-HT870's abilities, we cranked up the opening car chase scene from the "Quantum of Solace" Blu-ray and were blown away by the sound. James Bond drives his Aston Martin to the limit and the sounds of horse and firepower blasting out of the SKS-HT870 were plenty potent. Shock and awe dynamics were good, though not as freewheeling as they can be over our Aperion Intimus 4T Hybrid SD 5.1 speaker/subwoofer system ($1,569 MSRP) when it's used with a great receiver.
The SKS-HT870's center speaker handled dialog duties with the finesse; it was clear, clean, and articulate. Concert DVDs and Blu-ray Discs demonstrated the room-filling talents of the SKS-HT870's front and rear speakers. The spaciousness of the sound, floating free of the speakers themselves, was of the sort we associate with more expensive systems.
Jack Bruce's bass and Ginger Baker's drums on the "Cream: Royal Albert Hall" DVD had no shortage of visceral impact, and bass definition was decent. Eric Clapton's tasty guitar licks were warm and sweet. Yes, if we pushed the volume too far the SKS-HT870 sound thinned out and turned hard. Backing down the volume smoothed things out again.
CDs sounded just as good as DVDs and Blu-rays, the "rightness" of the SKS-HT870 was apparent with all kinds of music. We mostly listened to CDs in stereo, with just the front tower speakers and the subwoofer, and the soundstage was wide with a good sense of depth. The SKS-HT870's subwoofer doesn't have the gutsy punch and seriously deep extension of higher priced subs, but it was a superb match with the system's speakers. That seems like a smart design compromise to us.
While we didn't directly compare the SKS-HT870 with Energy Speakers' Take Classic 5.1 speaker system, the Onkyo system has size advantages that let it play louder, with lower distortion in larger rooms. We still love the Energy system for what it can do, but it's better suited to smaller rooms. Both the Energy and Onkyo systems are highly recommended.
