SB15P是108P和112P有源音箱的推荐伴随超低频音箱。系统的可操作频率范围低至40Hz。
SB15P具有15”直射LF传感器,内置在紧凑的低频倒置箱体内。优越的尺寸、频率和调整比率,SB15P把有源音箱的优势与DSP控制完美地融合在一起。内置15”传感器提供了远超想象的能量处理与ConeExcursion能力,并且增加了低热压缩和失真限制等好处。内置功放和DSP模块提供了优秀的驱动保护,同时也保证了音箱可以产生极高的SPL。箱体的设计和调整方式不仅优化了音箱的实时效果,还在极高工作电平时保持音箱的音乐连贯性和明确性。
SB15P装备有一个扬声器管理DSP和一个单通道功放模块。数字滤波器管理系统的交差网络和扬声器单元的高热保护。
SB15P箱体上方面板有一个固定插口,与108P或112P配合使用时,可以作为高雅的FOH或两侧补声。一个可调节的ETR支架可把多功能的SB15P固定安装在墙上或悬挂在天花板上。
SB15P 是一款推荐与108P 和112P 配套使用的超低频扬声器,可让系统的最低工作频率扩展到40Hz。
SB15P 包含一个15”的直射式低频扬声器单元,集成一个紧凑的反射箱体。具有最佳尺寸、良好频率和调谐功能。
SB15P 具有有源的优势和自带的DSP 控制, 集成的SB15P 扬声器拥有杰出的功率处理能力、振幅大、低热压缩和低失真。
集成放大和DSP模块确保最优化的驱动保护,同时允许箱体产生高的声压级。
箱体设计和调谐方法优化了箱体当前的行为和保持在最高操作水平的内在音质和清晰度。

Subwoofer TechnologyIn 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.
