Flatwire Speaker Wire Review

With the introduction of Dolby Prologic IIz, there are now two additional speakers: front height. Whether you want to add wiring to your theater room for these 2 extra speakers, or want to add wiring for a full 5.1 or 7.1 home theater system you are now building, there could be a question on how. My first system years ago involved running speaker wire up the walls all around the room. I did it in a way that was not too noticeable and fortunately my wife did not object too much. But it was still not ideal and was still noticeable.

Now there is an option. Enter a company called Flatwire. The product is just as it sounds. Flatwire is a speaker wire that is thinner than a business card, and is designed to go right on your wall. You can get the product in a kit, which includes the wire, spray on glue, and cloth mesh tape. Once installed, the wire is unnoticeable. But you will want to know a bit about construction, or get some help.

If you know what you are doing, the install is not too difficult. You will want to follow the instructions step by step. In a nutshell, you start by spraying glue onto your wall to hold the Flatwire. Once dry, you apply the mesh tape and mud to cover it up. After some sanding and a second coat of mud and some additional sanding, you are ready for the texture. After the texture is done you are ready to paint. Once done, you will never know there is speaker wire under there. My install looks great, and they sound great too! I could not be happier.

Epson Develops World's First 4K Compatible HTPS TFT Liquid Crystal Panel for 3LCD Projectors

Epson has developed he 1st 4K compatible HTPS TFT Liquid Crystal Panel for 3LCD Projectors. It will probably take a couple of years to make it's way into consumer models. Well, the timing is about right. After several generations of 1080P, what used to be top of the line quality can now almost be reached by the new generation of $1,000 projectors. Maybe this will be the panel used in the new Epson LCD projectors three years from now? I'm hoping it is LED as well. At 4X the resolution of 1080P, it should look pretty amazing.

To Dolby IIz Or Not To Dolby IIz, The New Question.

To Dolby IIz or not to Dolby IIz, that is the new question. There is a new surround sound contender, but let’s first discuss the history of Dolby surround sound. We did not used to have all the surround sound speakers that we have today. More is always better (supposedly) and that has been the route taken with surround sound. It is the route still taken today, with the desire for bigger and better.

It all started with mono. Just a single speaker or signal was all we used to hear. For ages that was all we had in sound reproduction. Then in the 50’s we got an upgrade to two speakers in the form of stereo. Stereo was all the craze back then. For decades that was the best we had.

Then in the 70’s came movies like Star Wars and Close Encounters of the Third Kind, and with it came the introduction of surround sound. This was thanks to the company we know and would all become familiar with- Dolby. Dolby Surround had emerged. Elevating the number of speakers to three it was the first innovation since stereo, and the first true surround sound format. The speakers were front left, front right, a phantom center channel created from the front left and right speakers (but not a discrete channel), and a single rear speaker for surround. For many years everyone was happy.

Next in the 80’s came Dolby Pro Logic. What it added was an additional speaker. We now had an actual speaker for the center channel. In the 90’s Dolby up’s the anti with Dolby AC-3 or more commonly known as Dolby Digital. Now we had the traditional 5.1 channels that we are all familiar with: Front left, front right, center, rear right, rear left, and subwoofer. Not only did we now have 5.1 channels, but they were also discrete. That meant that if a helicopter in a movie flew over from the front left to the rear right, you would hear it go from the front left to over you to the rear left. All 5 channels are also full range, so you could use large tower speakers for all channels if you wanted to. DTS also entered the arena as an alternative surround sound format.

Still not satisfied with the number of speakers, in 1999 Dolby Digital EX was introduced. This added an additional channel to the rear that was matrixed from the rear left and right speaker for a total of 6.1 or 7.1 speakers including the subwoofer. In 2000 Dolby went a step further and introduced Dolby Pro Logic II. Now, Dolby was able to matrix 5.1 from a stereo source. Next in line for Dolby came Pro Logic IIx which matrixed 6.1 or 7.1 from a stereo source. Dolby just kept adding extra speakers to the rear. We went from one to two, to now four rear channel speakers, with no change to the front soundstage. Now we have Dolby Pro Logic IIz, where Dolby has introduced two additional front speakers, as height speakers, matrixed from the soundtrack.
