YG SONJA XV3 四件式落地喇叭 (Sonja 1.1 + 1.2 + 1.3)，以高精密度技術，將航太級鋁錠以 CNC 加工，打造絕佳喇叭箱體，成就大頻寬、大動態、極低失真的卓越表現
YG Acoustics 核心技術：
CabinetTechnology 箱體技術，以整塊航太級鋁錠 CNC 製成。
FocusedElimination 消除共振技術，透過精準箱體幾何設計，從源頭將箱體內可能產生的駐波根絕。
DualCoherent 分音器技術，兼顧頻率響應與時間相位一致。
ToroAir 環形電感，讓低音運動更線性、更有衝擊力、更清晰。
ForgeCore 超低失真高音。
BilletDome 高音單體，以無共振軟圓頂振膜、CNC 製成鋁合金框架，完美結合軟絲質振膜與金屬振膜優點。
BilletCore 鋁合金振膜，以整塊鋁錠 CNC 製成，輕薄且表面應力平均。
ViseCoil 低音電感，安裝在鋁合金框架中，消除運作時的振動與縮小誤差。
