L-ACOUSTICS 阿酷司 SB18m 低音音箱 Products / SB18m subwoofer 低音音响 法国L-ACOUSTICS/阿酷司 SB18m 超重低音音箱
SB18m是ARCS WIDE和ARCS FOCUS线阵列以及L-ACOUSTICS其它移动系统推荐的超低频扬声器,可让配套系统的最低工作频率扩展到32Hz。
SB18m 由一个18”单元,与低音反射式结构的箱体组成。它具有紧凑、高灵敏度、低热压缩和低失真的特点。排风管拥有一个很好的剖面,更有利于气流的流通,减少紊流噪音,即使在一个非常高声压的操作水平。这些组合的特性有助于在精度和乐感方面保证SB18m 的声音质量。该箱体采用一级波罗的海桦木夹板构成,确保最好的音质和结构完整。
SB18m 超低频扬声器可吊装,或地面叠放,作为一个单独阵列或者SB18m / ARCS WIDE 或SB18m / ARCS FOCUS垂直组合阵列。其内置一个位于顶部面板的杆状插座,便可与一只XT 系列音箱、两只KIVA、一只ARCS WIDE或一只ARCS FOCUS组成一个整体。
SB18m 音箱可以由LA4 或LA8 放大控制器驱动和放大,这确保了在不同的工作模式下(包括心形)的系统线性化、单元保护和优化扬声器系统。
32Hz低频下限,大功率处理能力,低失真,低热压缩

In 2004 L-ACOUSTICS® introduced a new diffraction model, the DED. The Distributed Edge Dipole was published in the AES journal and provides a logical, predictable methodology for low frequency sound design. The DED model describes how a part of the wave produced by the speaker spreads toward the cabinet edges where it is diffracted with group delay and phase inversion. The DED model is implemented for modeling the physics of cardioid applications and the size of enclosures.
The latest subwoofer design incorporates a vent with a progressive profile and ultra-low vibration walls for a significant gain in peak SPL, laminar airflow and drastic reduction of turbulence noise.
L-ACOUSTICS® subwoofers benefit from the latest acoustic, signal processing and component innovations and deliver an exceptional level of performance while offering multiple modes of operation, whether on the road or in fixed installations.
