Many of audiophiles would also like to enjoy the cinema standard movie at home by leveraging on their already near to perfect HiFi setup. One can simply add on a pair or two of surrounding speakers plus supporting power amplifier.
From the mid level to high end, there are numbles of AV processor/Receiver/ Preamplifier which can manage the assigning of centre speaker channel. For example, Rotel 1570, Denon 4810, Classé SSP-800, Arcam AVR-600, Krell S1200 and many more.
In the setup menu, under speakers for channels assignment, one can make centre speaker disabled(No centre speaker connected), and then, the centre channel of the movies will be equally distributed in to front left and right main speakers. We all know that around 85% of dialogue,vocal or main effect all come out from the centre channel. If it had equally split into 2 and been distributed into front left and right channel, and came out from the 2 front speakers. The two same portion of central voice sound wave would be shot to the centre in front of the sitting place and then, head to the person's ears directly from the front. By seating the 2 front left and right speakers in the proper place, it would create a phantom centre channel even no physical centre speaker was in use.
The benefit by doing so is obvious. We know that hardly there's any centre speaker's frequency response can reach below 40Hz, even the best one, say, B&W HTM2 Diamond, can only responds 41Hz - 28kHz ±3dB. Taking advantage on the 2 front speakers' strength, however, would help us to extend the centre channel (phantom) frequency response down to 30Hz, or even lower than that, without any compromise on soundstage and sound quality.
One can alway argue that it can compliment the low frequency range by adding 1 or 2 subwoofer. Bear in mind the imbalance of sound filed could be caused. Meaning to say, in the movie, if the low frequency sound supposed to come from the front, then it should be produce via centre channel, adding 1 or 2 subwoofer may kill the shortage of physical centre speakers capability on low frequency voices, however, the direction of the sound where it come front could effectively confuse movies viewers, particularly in action movies which got people moving fast from and to different positions and and shoot each others, a lot of complicated sound need to be accurately matched and reflected.
Another benefit worth to consider is the cost. Nowadays, in the high end audiophile world, a good centre speaker which match the same series of the front ones, can cost up to £3950. By using the phantom centre speaker instead, people can eliminate this unnecessary cost and spend the money on more important components.
