"Best Functional Speakers are about Location Setup"
In getting the best results out of your home theater system, location and setup of your home theater speakers determine the effectiveness or perceived amplitude of the sound, depending on constructive or destructive interference, besides impacting reflection, absorption, diffusion or diffraction of the sounds.
With most rooms having 3 pairs of parallel surfaces, the
location of the home theater speakers will determine the presence or absence of standing waves, affecting the rate and intensity of the reverberations. While reverberations can be controlled through alteration of the wall surface to promote absorption, or diffusion, as a general rule, high frequency sounds are absorbed more readily than low frequency sounds.
Besides this,
the setup and location of the home theater speakers will determine the exact location of the sweet spot where the sound or music is heard at its best quality. There are various different speaker set-ups for home cinema speaker systems.
The include the 5.1, 6.1, 7.1 channel sound, with the 5.1 channel coming with left, center, and right front speakers, left and right surround speakers, and a subwoofer. 6.1 channel comes with similar capabilities along with an added center rear channel, with the 7.1 having two rear speakers. Further options in this regard are the dolby DTS or THX surround systems.
