This system rocks!


New Egg prompt service and competitive pricing sealed the deal for me. Free shipping made it even better.

This a/v home theater system has it all. Easy connections for both audio and video with high quality digital audio and high definition video component input

No HDMI in or out

Awesome set


Affordable, great sound, everything you need in the box. Really nice having video pass through which isn't found on some cheaper receivers. It is very nice to sit down with just the receiver remote and flip between Cable, Xbox360 and Wii instead of...

Can't really think of any

HIGHLY recommend. very cheap for its performance. Get it, you will not regret! still on sale so hurry.

It sounds AMAZING. Very easy to set up, all color coded for the less tec savy individual ; I cannot stress this enough... I'm a huge technology guy.. computers, sounds, etc... and it sounds great. I own a logitech z5500 for my computer set up, great...

None... optional IPOD dock that i thought came with it, too bad

Amazing Surround


This is great for the price. I highly recommend this to anyone looking for a nice 5.1 setup, or people who are just starting in home theater.

Ok. Reading the reviews, I wasn't sure if this surround was going to have great bass or not. Boy does it though. I set the dB settings for the sub to 10 (goes much higher though) and the bass in my room is already shaking things. The whole system...

I couldn't find my wire I was using scissors for a little to cut speaker wire. Well the actual real con would be the speaker wire that comes with it. Its garbage. I bought some other speaker wire

Great System


Great system for an out of the box surround sound, easy setup as long as you can understand a diagram.

none, you get what you pay for

Great System.


I've purchased two other "Home Theaters in a Box" in the past 6 years and they do not come close to the sound of this system. Mind you, this system isn't going to produce the same sound as a $3000.00 system, but for $269.00 it will do a great job.

The speakers on this system are great. Not a higher end speaker, but for the price they sound great. I swapped the Onkyo receiver out so I could use my Sony STR-DG710 and the sound is excellent. I use these in my livingroom for surround and have no...

None so far. The Onkyo receiver is being used in my "man cave" for music so I'm not sure what it's real potential is.

Huge! The pictures don't really do it justice as far as size so I was surprised. The Sub-box is the size of a TV tray squared almost :)

Great system for the price! I have a smaller living room and from the sound this thing makes, it seems like your right in the middle of the action for movies and gaming.

Only con is it doesn't have any HDMI but I am perfectly content with it.

Great home theater system


For an outstanding price in relation to what your getting, I don't think you could find a better option than this Onkyo system. Very happy with my purchase. And buying from NEWEGG makes the purchase all that much better, ordered this on a Friday...

Has many connection options, 2 Opitcal inputs which is pretty much unheard of on a set this inexpensive, very good looking speakers and an ideal size. It does have a passive subwoofer but don't let that fool you. Correctly dialed in and this has more...

Cons are subjective to what product your buying, go into the purchase knowing what your buying. There shouldn't be any cons if your happy with your purchase and are getting what you paid for. Which in this case is very well done home theater system...

Great System


This is a really sweet home theater system. The sound quality is surprisingly good. It has three digital sound ports, two digital optical and one digital coax, so you can work around the HDMI lack. It is what you pay for, but if you are cost conscious,...

Great sound, easy set up.

No HDMI port.

kinda big


satisfied but i was looking to find something less expensive.

Works with my ps3-80 and vizio42hdtv using hdmi from ps3 to vizio42hdtv and then optical audio out from the VIZIO back to the onkyo-s3100.

This thing, for a HTIB, is rather large and looks bulky under my slick looking ps3

Product Specifications

It's easy to get excited about home theater that's easy on the wallet. The only downside is that most packaged home theater systems have largely missed the target. It's all about covering the fundamental A/V considerations - that's the design focus of the HT-S3100 5.1-channel receiver / speaker package. Where others fall short, the HT-S3100 covers today's key entertainment options - DVD video, audio CDs and digital music files, TV and satellite broadcasts, and gaming. With the reliability of component video, you can even bring Blu-ray Disc and HD DVD into the mix. And as with all Onkyo A/V components, the HT-S3100 has a trademark amplification design that puts power and precision before all else.
