Product Description

Amazon.com

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.

    I would recommend this product to anyone seeking to replace their existing home theater system speakers or looking for an upgrade.

    I'm using the speakers with the Onkyo TX-NR809 THX Certified 7.2-Channel Network A/V Receiver (Black) and it's a great match!

    I am happy with this speaker set because, in my view, I got a lot of value for what I paid. I wouldn't call myself an Onkyo fan when it comes to entertainment devices - Sony receiver, Sony PS3, Sony BD player, Samsung TV - but I am aware of Onkyo's reputation for quality and this set of speakers doesn't disappoint.

    All prospective buyers should be aware that these are 6 Ohm (SIX OHM) speakers. They will work well with 6 Ohm receivers, of course, and you SHOULD be able to use them with an 8 Ohm receiver if it's kept in a well-ventilated shelf and you don't keep it continuously at full blast. My own receiver is 8 Ohm and it seems to be Okay but both Onkyo and the receiver maker may not want to honor the warranty if they get word of this.

    CONTENTS

    What you get is good quality, 130W speakers encased in well-built wood boxes, a 290W powered woofer and then, there are a couple of unexpected bonuses.

    - 1 Center speaker, surprisingly large
    - 2 Front speakers on 'tower' stands (tallboy) - will save you money on speaker stands but if you're thinking about hanging them, this is not your set.
    - 4 Satellite speakers - do have hanging holes
    - 1 Woofer - powered, connects through 'banana' jacks on both ends
    - Color-coded wires for each speaker - kind of thin and I used my own, see below but... they're free
    - Onkyo UP-A1 Dock for the iPod - this was totally unexpected

    SETUP

    A screwdriver will be needed to attach the heavy metal base to the front, floor-standing speakers.

    If you go with the color-coded wires, connecting everything is easy.

    I had been looking for a reasonably priced 7.1 system, this one has been perfect. The speakers are unobtrusive, and reasonably sized, and the sound quality is great for a sub-$400 system. I wasn't aware when I purchased the set that it also includes the Onkyo UP-1A iPod adapter, while I have no idea why it is included it was a nice bonus, however I suspect that the $90 optional adapter increased the price, and it only works with Onkyo receivers (I have a Sony), for Onkyo Receiver owners this could save an extra purchase. I put mine up for sale on Amazon marketplace. The sub is more than adequate for the 14x14 room that I have my TV in, and the surround effect is spot on. All in all, I'm quite pleased with the quality of construction and the quality of the sound. The included speaker wire is good in a pinch, but I opted for thicker Monster speaker wire, I don't know enough about wire to tell if it made a difference, but I thought it was nice that the wire was included...

    Okay, so look. Any hardcore audiophile is going to build their home theatre from the ground up and probably frown on "bundles" like this. However, Onkyo's quality has substantially increased recently and these speakers do represent that. I have these speakers hooked up to a Sony STR-DH810. I measured the distances, inputed them into the receiver and balanced them. It took a lot of tweaking before I got everything to sound right. I did have some problems with the center channel being drowned out so I bumped that channel slightly above the rest. If you want this system to sound the best it can then I please urge you to NOT use the speaker wire included.

    The speaker wire that Onkyo provides will not handle lossless mixes well at all. You may get crackling and peaking and everything will sound flat. I re-wired with decent speaker wire and the difference was night and day. Sounds are richer and more full. Dialogue is crisp and doesn't cause peaking or crackling in the center channel. So do yourself a favor and toss the shoestring wires and get a 100 feet of THX certified Monster Wire for $21 here on Amazon.

    All in all I love the sound. They are not the best but for the price they are extremely good. If the center channel could stand its ground better then the set would be exceptional. One day when I have a higher salary I will no doubt build my setup speaker by speaker, but for now this is as good as bundled packages get.

    Based on all of the positive reviews, I paired this 7.1 speaker system with my Onkyo HT-RC360 7.2-Channel Network Audio/Video Receiver (Black) in my gaming and TV area. I am quite pleased with the sound and the appearance of the system. My receiver supplies 100 watts per channel into 6 ohms for these speakers. The result is a clear and balanced sound for a very attractive price.

    SETUP

    Hooking the speakers up was extremely easy with my Onkyo receiver. Each speaker is clearly labeled as to room placement and the wires supplied with the speakers are color coded for the correct receiver connection - six different color wires match six different color receiver speaker connections. It was nice to be able to run all of the wires without stopping to label anything. The only thing that needs assembly for any of the speakers is attaching the weighted footing for the front side speakers.

    LISTENING EXPERIENCE

    After I set the speakers up and calibrated them for the room with the receivers Audyssey 2EQ, I threw on "The Hurt Locker" to get a good combination of dialogue, explosions, gun fire, helicopters, things driving by etc. The system performed excellently. Nothing was too loud and voices could always be understood - even in the action scenes. There was ample volume. In fact, I can't imagine turning things all of the way up on this system as it would be uncomfortably loud.

    BOTTOM LINE

    Straight music playback was solid for a 7.1 system. Obviously, these speakers pale in comparison to my Klipsch for music reproduction but they are a fraction on the cost and geared for surround sound.
