Wireless Audio and Video Solutions

In the previous post, I have discussed how to stream the Audio and video wirelessly. In this post, we will see how to make the end to end connection without wires both for Audio and Video. It is not very difficult to find a gorgeous looking high quality Amp and matching speaker sets (5.1/7.1/9.1 systems ) which goes with your room décor at a reasonable cost. But the wires crisscrossing the room interconnecting all these equipment will be an eye sore and invite the wrath of your better half. Let us see how to connect the speakers and TV without those ugly looking cables. Moreover a wireless connection gives you lot of flexibility in the placement of your equipment and speakers.

Wireless speakers come in different size and shape, employs different technologies to deliver reasonable good sound output. Apart from the Bluetooth speakers the most common one is wireless rear speakers employed in 5.1 systems. Wireless 5.1 rear speakers are common offer from most of the Consumer electronics companies as part of their all in one Home Theater solutions. But these suffer from poor quality and no wireless system can match the performance of connecting the same set of speakers with wires. Do not forget that the powered speakers / RF transmitters need power so you cannot do away with the power chord for a good sounding wireless system L

Wireless speakers can be broadly classified into the following 4 categories

  1. Wireless PC Speakers
  2. Wireless Surround Speakers
  3. Wireless Outdoor Speakers
  4. Bluetooth Speakers

In terms of technologies employed it can be any of the following.

  1. Bluetooth speakers
  2. Wi-Fi speakers which can be directly plugged into your Wi-Fi networks (This is coupled with media streaming)
  3. Works in 2.4GHz but employs proprietary technology which is most common and better sounding

Cue Acoustics SP1 Wireless Speakers 

Cue Acoustics' wireless PS1 speakers is single box solution with amplifier is also built into it. It aspire to be high quality speakers which can stream from audio devices and won’t cost you as much as a pair of tower speakers. PS1 speakers consists of a 3/4-inch tweeter, 3.5-inch midrange speaker and a 5-inch, down-firing sub-woofer built into the underside of the speaker.

That means all you need is a device capable of pushing an audio signal to the speakers and you're good to go. The one thing you need the wire for at all is for power. You can also connect wired sources, like TVs to the speakers using an optical cable or analog cables.

Philips SoundBar (HTS5131) 

From the discussions so far, it is easy to make out that all the wireless solutions outlined here is a compromise, either in quality or cost or in its application. There is no really cost effective way to have wireless 5.1 or 7.1 professional speaker systems with all the 7 speakers in place. The wireless solution is limited to rear speakers; otherwise it will come at a prohibitive cost.

In this scenario where space is also at premium, Sound bars offer good quality solutions where high quality Amp and speakers are integrated. Subwoofers come separately which is wireless or wired depending on the model. As the inventors of SoundBars, Philips is still regarded very high for its soundBar solutions. SoundBars provides a virtual surround sound sonic experience from an integrated unit which can be placed under the TV either wall mounted or placed on the TV stand itself.

Philips SoundBar HTS5131 has a built in BluRay Player, integrated surround sound speakers and a separate subwoofer. It comes with both Dolby True HD and DTS Master Audio decoders and capable of connecting to internet and stream YouTube videos and online photos. It doubles up as a media player which plays most of the formats. It can connect to your iPhone using iLink technology to stream high quality music.
