XPA系列线性扬声器箱体采用多层AAA级桦木板材装嵌而成，箱体坚固耐用，更能适合长期的流动演出舞台、剧院、会堂等，并且最大限度降低箱体重量。箱体外部采用新型哑光聚安酯涂料及喷涂技术工艺处理，抗腐蚀、抗撞击、耐磨、减少音响的损坏。 XPA系列线阵采用独有的中音单元组合，因此，XPA线性扬声器既有极好的覆盖面控制，在扬声器覆盖范围内声场分布均匀，一旦超过覆盖范围之外会急速衰减，在精密的设计后，扬声器群组的各个频率范围互相不会造成干扰。XPA线性扬声器是一个垂直阵列而设计的高能量曲线系统，它有足够的声压级可用于高水平的大型场馆，高度还原现场感，扩散角度大，覆盖均匀。 XPA线性扬声器设计的另一个重要的特点是针对号角喉管中空气的非线性，对号角/驱动单元进综合处理，最大限度地降低了失真。中高频部分采用分散补偿设计，最终表现为各种频率生成连续的、一致的波阵面和极似的分散模式，与其他线性技术相比，其信号处理对于排列中的所有的扬声器，其输入水平是相同的。而且使用了波阵面尤其是垂直分散或扩展所存在的变量，从而依据所需的发射距离来改变声压级，这主要同改变排列的曲率来实现的。

Linear speaker cabinet XPA series by using multi-level AAA birch plank assemble and become, cabinet more durable, suitable for long flowing performance stage, theatres, synagogue, and to minimize the body weight. Cabinet together with new dumb light external install ester coatings and spraying technology processing, corrosion resistance, impact resistant, wear-resisting, reduce sound damage. XPA series linear array used the unique combination, therefore, alto unit XPA - 8 linear speaker both excellent coverage control, the speaker within range of the acoustic field distribution uniformity, once more than coverage will rapidly outside in precision design damping, after all, the speaker group will cause interference each frequency range.

XPA linear speaker is a vertical array of high-energy curve systems designed, it has enough level can be used for high levels of large venues, height, the diffusion Angle XianChangGan reduction, enclothe even. Loudspeaker design XPA linear another important characteristic is aimed at the air in the horn pipes of nonlinear, horn/drive unit into comprehensive treatment, maximize reduce distortion.High frequency part adopts dispersion compensation in design, final expression for various frequency generating continuous, consistent wavefront and extremely similar scattered pattern, and other linear technology, the signal processing compared to all the speaker, arrange the input level are the same. And USES the wavefront especially vertical scattered or expand the variables that exists, thus basis to change the distance needed to launch, this basically level with change to realize the curvature of the arrangement.
