I will look at the latest trends to determine which devices really work. Newer 7.1 systems need a total quantity of 8 loudspeakers by adding 2 additional side speakers. Thus the installation of home theater products has turn out to be a relatively difficult process. Suppliers have recently released new products and technologies.
One solution is minimizing the number of loudspeakers by making virtual speakers. This method applies signal processing to the sound and adds phase shifts and cues to the audio that would normally be sent by the remote speaker. An additional approach for simplifying home theater setups and eliminating long speaker cable runs is to utilize wireless surround sound devices or wireless surround speakers from www.amphony.com/products/wireless-surround-sound.htm. A wireless solution will generally include a transmitter module that connects to the TV or source and in addition wireless amplifiers that will be connected to the remote loudspeakers. Several wireless products have wireless amplifiers that connect to two speakers. This still requires wire runs between the two speakers. To be certain that all loudspeakers are in sync in a multi-channel application, ensure that you select a wireless system that has an audio latency of just a few milliseconds at most. A number of wireless systems work at 5.8 GHz which offers the advantage of less competition from other wireless products than devices using the crowded 900 MHz or 2.4 GHz frequency band.
