在车内前声场中,坐有皇帝位、视有液晶屏、听有二分频,车内最好的视听资源基本全集中在前排声场,除了后备厢低音箱或有源低音外,车内听感最薄弱的环节莫过于后排声场了。限于B柱的承重支撑功能等,后排声场在安装时会受到位置等种种因素制约,因此,不少原车后门喇叭多采用同轴喇叭改善和提高声场效果。如去年底上海通用别克换代车型新君威的音响系统,新君威高配版共有11个喇叭,号称5.1声道,在前排声场,新君威在中控台上有中置中低频喇叭,前门6.5英寸二分频套装喇叭,后声场则采用了同轴喇叭。这种安装方式也广泛的存在于汽车音响改装店的器材解决方案中。本次测评的铁将军4款同轴单元就是为弥补原车后声场不足而打造,喇叭也从4×6英寸、4英寸不等。
In the car before the sound field, sitting there Emperor, depending on the LCD screen, listening to the second frequency, the car’s best complete audio-visual resources in the front sound field, in addition to the trunk subwoofer or active bass, the car The weakest part of the sense of hearing than the back of the sound field. B-pillar load-bearing features such as limited support, the rear sound field in the installation will be subject to a variety of factors such as location constraints, therefore, many of the original car rear speakers and coaxial speakers to improve and improve the sound field effect. At the end of last year Shanghai GM Buick new Regal car audio system, the new Regal high version with a total of 11 speakers, known as the 5.1 channel, in the front sound field, the new Regal center console in the middle and low frequency horn, the front door 6.5 inches Fractional package horn, after the sound field is the use of coaxial speakers. This installation is also widely present in the car audio conversion shop equipment solutions. The evaluation of General Iron 4 coaxial unit is to make up for the lack of sound field after the original car to create speakers from 4 × 6 inches, 4 inches range.
