I have heard that 5 matched loudspeakers are recommended for 5.1. Why does THX recommend something different?In a movie theatre, the surround speakers and the front speakers are different because they do different jobs. The front speakers provide clear dialogue and are designed to localize sounds to match the picture. The surround speakers create diffuse and enveloping surround ambiences with occasional effects like pans or "fly-overs." If you decide to build a 5.1 channel home theatre system out of conventional loudspeakers, using 5 matched speakers plus a subwoofer is the minimum requirement. Home THX Speaker Systems are designed specifically for multi-channel sound. THX LCR Speaker and THX Dipole Surround designs psychoacoustically match the best surround sound performance of a movie theatre or mixing stage. The THX subwoofer keeps the size of all of the speakers small while allowing for peak dynamic range and bass performance. back
| | 我听说5个同样的音响最适合5.1声道的回放。为什么THX推荐的方法不同? 影院中环绕音响和前方音箱不同,这是因为她们的作用不同。前方音箱用来负责清晰的播放对白,提供和图象相符的声音定位。环绕音箱创造环境声的扩散和包围感,以及偶尔的平移和掠过头顶的效果。如果要用普通的音箱建立5.1声道的家庭影院系统,用5个同样的音箱加1个低音炮是最低要求。家用THX音箱系统特别为多声道设计。THX"左中右"音箱和THX偶极环绕音箱为符合电影院和录音棚的环境心理声学特性设计。THX低音炮设计用来在减小主音箱体积的同时保证低音的音色和系统的动态范围。
