不要认为长的像号角的或者有英文字样horn的就是真正的号角。
应该还是典型的horn,下面一段摘自官方网页
Innovative horn technology
The spherical horns are the trademark and the core technology of Avantgarde Acoustic. The horns are responsible for the high sensitivity and the ideal dispersion characteristics of our speakers which makes the systems so amplifier-friendly and so easy to install.
Horns made of ABS-resin: no resonances, acoustically neutral, robust
High pressure injection molding technology: extreme precision (+/- 0,05 mm), perfect surface quality, efficient and rational production method (for outstanding price/performance ratio)
Spherical horn function: computer based calculation of the precise horn contour (for highest efficiency and ideal dispersion characteristics)
Compression-free driver/horn coupling: optimal, neutral and distortion-free coupling of the driver to the horn throat
CDC-System: acoustical filtering of the frequency range, dramatic reduction of passive crossover components, thus eliminating phase problems and dynamic compression
Crossover-less midrange (UNO & DUO ranges): pure and undistorted signal processing without typical losses of passive crossover components!
horn的形态五花八门但主要作用无非两个,给驱动器加载(改善与空气的耦合)和控制声音的指向性
再看这个网页http://www.6moons.com/audioreviews/duomega/upgrade.html,图片中显示的Avantgarde具有典型的horn的特征,比如高频单元是典型的压缩驱动器等等,
现代喇叭中有些比如amphion给普通球顶高音加上浅号角或者叫Waveguide当然离典型的horn较远,但严格说来或多或少都有前述两个作用
既然bruce有前面关于Avantgarde和号角的说法,还望进一步阐明 |
