    Onkyo SKS-HT870 Reviews

    SKS-HT870 7.1-Channel Home Theater Speaker System is rated 4.7 out of 5 by 44.
    Rated 5 out of 5 by from Room Shaking Performance! Bought these along with a Denon Receiver to replace my Samsung HT 'in a box' and I was not disappointed! These speakers are well crafted and look perfect in my HT room. I used hanging mounts for all the surrounds with no issues. The performance has been outstanding, they literally shake the furniture! My Samsung speakers would crackle under intense sound (death star blowing up, any time Sauron saw the ring, etc. lol) but these handle it all with no issues! I did buy my own speaker wire and subwoofer cable for them as this was recommended in many reviews, just normal 16 ga (and a better RCA cable for sub) but it was thicker than what was provided. Sounds great, looks great, and a super value.

    Rated 5 out of 5 by from Hands down the winner is.... B&H met and surpassed my needs. I came to them as a second choice my first choice while they had a lower price failed to mention shipping was extra after I added one week ground shipping cost was comparable to B&H's free next day shipping! Not to mention distributor A didn't even have my unit in stock and wanted me to wait three weeks for delivery. Ari in electronics was more than helpful knowledgeable and polite. Needless to say after hanging up with him I was installing my surround sound system two days later and at a price cheaper than Amazon Prime! I'm happy with the service and I will definitely make them a first choice in the future.

    Rated 4 out of 5 by from Great system for the money Excellent quality and workmanship. Feels very solid and shipped in a package that looked like it could survive a nuclear war... I finally upgraded from an all-in-one surround system to a nice home theater receiver. I wired a new home for 7.1, so I wanted a speaker package to match. Setup was very easy. Although I was not ecstatic about the spring clips in the back of the speakers, they do seem to be sturdy and hold the wires well. The package did include its own speaker wires, but I did not use them. It seemed like a nice touch, but the wires looked a bit thin for the power I intended to push through them with a higher-end receiver. I was impressed with the center channel - (which is something I found severely lacking on my last set). It sounded quite full and did not sound 'tinny'. I don't know if this is a limitation of my receiver or not (Yamaha RX-V673), but I found that I had to really crank up the subwoofer in order to get that booming sound while watching cable or a Blu-Ray. Other than that, I am quite happy with the set. Side note - I did find that the speaker stands I bought for the satellite speakers did not quite work due to the larger size of the speakers. I had to do some creative rearranging of the back speaker bracket in order to get them on there properly. Be sure to look at the dimensions of the speakers before you commit to a set of stands. I would definitely recommend this set to anyone. The speakers really pack a punch that should be more than any normal-sized room can handle. My room is 20 X 20 and I was blasting my wife's ears at about half the volume. Please note that these speakers operate at 6 ohms, so be sure your receiver can accommodate something other than the standard 8 ohms. B&H was awesome and had the set to me in record time (even with their other holiday volume). I highly recommend getting this item from them. They really stand behind the products they sell. Also, FREE shipping on a box that weighs 78 pounds is simply mind-blowing..

    Rated 5 out of 5 by from Great sound and affordable! After doing much research for a good sound system within my budget range, this bundle is the result. Right now I'm using it in a small area but it could be used in a larger area than I have and still sound fantastic. To be quite honest with you, I was totally blown away by the sound produced from these speakers and even more so by the price! If given the chance, I'd buy this setup again!

    Rated 4 out of 5 by from did lots, lots, and lots of research pretty happy with everything I got for the money except the sub makes an annoying noise went it automatically shuts itself off when no bass is being transmitted. This is super annoying especially when watching a movie. I'm sure this saves electricity but would rather it just shut off automatically when receiver is turned off or a longer delay, like a delay long enough to finish a movie.

    Rated 5 out of 5 by from Great sound at a great price! This is a great speaker system. I've connected it to the Onkyo TX-NR609 and the sound is great! Set up was a breeze thanks to the color coded wiring that's included. I've connected an HD radio tuner and a blu ray player to my receiver and the sound I get from these speakers is outstanding for an all in one speaker system. I'd definitely recommend this system to anyone.

    Rated 4 out of 5 by from Good but no great. It is a good value, looks good, the sub woofer has a nice finish. If you want thunderous sound, look somewere else.

    Rated 5 out of 5 by from Great System I'm using this system as in my basement home theater. I have these hooked up to a Denon AVR-1912 Receiver, and an Infocus Projector. The sound quality is amazing, the base really shakes the house. I haven't been able to get the auto setup to work correctly yet, so I manually set the levels, which seems to be good.
