    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.

    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.

    One of the main reasons i purchased this set is because it has the tall front L & R speakers, has great reviews on Amazon and CNet. Really great sound quality for the price. This is connected to my Onkyo TX-SR505 Receiver that i purchased about 4-5 years ago and set at 120Hz. I've actually set this up as 5.1 surround in a 20x25 room with TV, PS3, iPod and turntable and have connected the 2 remaining speakers in a different room as speaker set B (front L & R) on my receiver to pipe music/sound to my other entertainment room. Having it only setup as a 5.1 in a large room, i must say, the sound quality is impressive. Surround is fantastic, bass is powerful, low and crisp (Not muffled or distorted) and rocks the house pretty well. Front left right and center speakers are very crisp and hi's and mid's are very sharp (I also diverted all my bass to the front L & R speakers just to see how it would handle, which they did with ease while listening to some bass intensive rock from my turntable). Call of Duty: Black Ops on PS3 w/ surround is stunning, I'm positive my neighborhood feels each gunshot, bass rocks. Great Speaker set for the price.

    Update 1/9/13
    I thought I would update this because I usually like to research quality over a period of time when I purchase something. These speakers are used several hours daily for TV, blue ray, PS3 gaming, and/or music via iPod or record player and often at high levels. They are still producing extremely high quality sound and continue to be impressed by the quality especially during football games, high intensity blue ray movies and gaming (Call of Duty: Black Ops 2 being the latest).

    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...
