Question: Can anybody tell me how wide the speaker arrays are without the stand. I have limited space. Thankyou
Document: I think it is about  the size of my last system. This is a huge plus and makes it easier to find a place for it and it doesn't take up too much space. We have a lot of different electronic devices so small and compact is welcomed in our house as long as it's still of good quality.It comes with two long and slim mid-range speakers, a small center channel speaker and a wireless subwoofer.
This is a great entry-level surround sound system, expecially if you have a room with limited size like I do. The set-up was hassle-free, it took my half an hour to install it, and everything worked without a hitch. The speakers have nice finish, a good complement to our entertainment center.
The Panasonic SC-HTB770 3.1-Channel Soundbar with Wireless Subwoofer was an absolute breeze to set up with our home media centre which is in the largest room of the house but we still have limited space.Because most of the equipment I have is Panasonic already, we really didn&#8217;t have the compatability problems that others have reported in their reviews. The bluetooth pairing made setup really easy.
The  Dolby Digital, Dolby Pro Logic II, Dolby Virtual Speaker and DTS technologies used in this system do a great job in making the sound feel immersive and life like similar to a 5.1 system. The center speaker sounds great and Dialog is clear and easy to understand.The system was also a breeze to set up and linked to my 42ich Insignia 'INsync' system without any problems.
My background is IBM PCCo. project/product manager for World-Wide quality. Based on my experience with this unit, I believe Panasonic failed during development cycle of this product to perform what we at IBM called an "environmental test". Basically, cycling temperature (freezing to hot) to stress the components and board circuits.
I find myself getting up to look at the front of the box and that pretty much makes using a remote control pointless.You can either hook this system up with an optical cable or HDMI cable. After reading the instructions it was suggested that for my application I should go the optical cable route. The system was easy enough to set up and I had it up and running within a few minutes. Just plug in the power cord, speaker wires and optical cable and I was all set, very simple.
When I searched this model from their drop down list, its not there. If you are lazy like me and want one remote ( if you have Panasonic Vierra TV) then this will be good product. But sound quality is not really much to spend another 300 bucks.1/13/2014 : New Update : After 3 weeks received SU-HTB-70 ( base unit) and its not working. They send another repaired unit which won't connect to Sub Woofer. In Standard mode only left speaker works.
The wireless subwoofer is easy to hide away anywhere in the room and works great. It also has a built-in Bluetooth option so you can stream music to it from a wide variety of different devices. I stream music from my iPad and it works perfectly and sounds great. This gives this system a lot of flexibility. So far so good right?
Our new sound system is great. It feel like we have a home theater without the cost. I love the wireless speakers. We can put it any where we want.
With the flexible speaker setup, the great features, and the price so low you can't even buy a subwoofer for that kind of money, it's a no brainer.
Answer: If you use all of the speakers together as a horizontal soundbar (left/center/right speakers all attached together), the entire soundbar measures 49-1/2 inches wide, 2-3/4 inches tall, and 1-1/2 inches deep (front to back). There is no separate "stand" if you use the unit as a horizontal soundbar (just some very small, maybe 1/8 inch thick, plastic/rubber "feet" to raise if off of a cabinet surface). If you separate the left/right speakers from the center channel unit and use them as separate vertical speakers (which is the way I'm using them; placed on either side of the cabinet), there are two 1/4-inch thick by 5-3/4 inch square plastic base/stands included that attach to one end of each left/right speaker. Separately, each left/right speaker is 21-1/2 inches tall if you stand them each up vertically using the plastic bases. Each of these left/right speakers are 2-3/4 x 1-1/2 inch in girth (and as mentioned, the base stands are 5-3/4 inches square). The center channel speaker by itself is 7 inches wide. The separate wireless subwoofer is 11-3/4 inches (front to back), 7 inches wide, and 15-3/4 inches tall. Note that the subwoofer has an on/off switch on its backside, and it needs to be turned on and off manually (it does not power up wirelessly when you turn the main power unit on, and I found that it didn't seem to want to link up wirelessly with the main unit even if it was only about 8 feet away from the main unit; I have our subwoofer tucked in behind the angled TV cabinet that we have, so it's only a foot or two from the main unit). So be sure you place the subwoofer somewhere relatively close to the main unit and easily accessible so you can reach it to power it on and off. I hope this helps.
