该系列产品是利用最新扬声器电脑设计模似技术结合最新扬声器应用材料、加工技术而开发制造的一系列扬声器系统产品。所有扬声器单元均采用最优化的高磁能、低失真、良好通风冷却的磁路系统。在保证音质的同时，大大提高了产品的可靠性。

VR20音箱产品采用三分频设计，内置2只10” 低频单元，1只8” 中频单元，以及2只1.4” 高频压缩单元。VRS25音箱产品内置两只长冲程钕磁驱动单元，一只低频反射式设计的 18” 驱动单元朝向前方；一只双腔体带通设计的 12” 驱动单元朝向后方。这种分布结构所形成的心型指向特性可以避免音箱背面产生多余的声能，减少低频区激发混响声场，并提供最佳的低音保真度。可作为全频音箱的低频扩展，能够应用于各种不同的组合；如地面堆叠或吊挂，也可将它安装于线阵列的顶部或作为独立的低频音箱组。

VR20 speaker adopts three frequency design, with two 10" LF units, one 8" MF unit and two 1.4" HF compression units. VRS25  has two long stroke neodymium magnetic drivers, one 18" driver with low frequency reflection design faces forward, and one 12" driver with dual cavity band-pass design faces back. The heart-shaped directivity formed by this distribution structure can avoid the redundant sound energy generated on the back of the speaker, reduce the reverberation field excited in the low-frequency region, and provide the best bass fidelity. It can be used as low-frequency extension of full frequency speaker, and can be applied to various combinations; such as ground stacking or hanging, it can also be installed on the top of line array or as an independent low-frequency speaker group.
