Speaker Placement

This huge array of speakers assures that you will feel completely surrounded by the ambient soundtrack of the movie. Film makers try to use the “surround” soundtrack to envelope you in the envi- ronment on screen. They will place back- ground music, rain sounds, traffic noise, etc. on the “surround” soundtrack. In a home with a single pair of speakers it is easy for the jungle sounds to sound like they are “in the middle of your head” just like headphones!

A single pair of BG Loudspeakers, proper- ly placed, can create a very convincing simulation of an array of speakers. If you place them near a hard reflecting surface you can make one pair of speakers sound like several. Create as many reflections as possible by mounting the speaker up high in the wall so that the ceiling will act as a powerful reflector. If you place the speak- ers near a corner, wash the sound down a wall from a ceiling location, or mount the speakers as far away as you can from the listening area, more reflections will occur. However, all of these placement tech- niques require that you work your sur- round sound amplifier channels harder. If the surround sound system you are using has a small five or ten watt amplifier for the rear speakers, stay within five to eight feet of the listening location. If you are using a 25 to 50 watt amplifier you can mount the speakers 10 to 15 feet away from the listening location and still achieve reasonably high volume levels.

Of course, the best way to emulate the sound of multiple speakers is to use multi- ple speakers. In large or unusually shaped rooms this might be the only way to achieve a good effect. If you like to listen to music surround modes which emulate concert hall acoustics, more than two sur- round speakers will prove extraordinarily effective. With Niles BG loudspeakers it is easy to add another pair without affecting the decor of the room. However, you will need to use a much more powerful ampli- fier than that which is built into a typical surround sound receiver or amplifier. Niles makes a number of Systems Integration Amplifiers with proprietary fea- tures that make them uniquely suited to enhance a good surround sound system.
