Barefoot Sound LFE15 双驱动力有源超低音音箱。

用途：适用于专业录音室打造环绕混音系统、构建杜比全景声配置，也适合追求极致音质的音乐爱好者，为沉浸式音频设置带来震撼低音效果。

技术原理：采用双驱动力技术，两个 15 英寸的驱动单元分别置于箱体相对两侧并通过电机锁定，一个驱动单元向某方向施力时，另一个以匹配的力反向运动，抵消箱体震动，减少因震动产生的失真和音染。

性能：内置 1400 瓦功率放大器，最大声压级可达 130dB 。频率响应最低至 15Hz。设有增益选择器，可提升 10dB 增益。具备两种工作模式，Boost 模式通过一阶最小相位低通滤波器，在立体声设置中增强和扩展低频；LFE 模式激活四阶低通滤波器，可选择 80Hz 或 120Hz 设置，适用于提升环绕声系统中的低频效果声道。还配备低通滤波器（LPF）控制，可根据房间声学特性优化超低音音箱响应 。

Product Name：Barefoot Sound LFE15 Dual - Force Powered Subwoofer.

Purpose：It is suitable for professional studios to build surround mixing systems and Dolby Atmos configurations, and also for music lovers who pursue ultimate sound quality, bringing shocking bass effects to immersive audio setups.

Technical Principle：It adopts dual - force technology. Two 15 - inch driver units are respectively placed on opposite sides of the cabinet and locked through motors. When one driver unit exerts force in one direction, the other moves in the opposite direction with a matching force to counteract cabinet vibrations and reduce distortion and coloration caused by vibrations.

Performance：It has a built - in 1400 - watt power amplifier and can reach a maximum sound pressure level of 130 dB. The frequency response can be as low as 15 Hz. There is a gain selector that can increase the gain by 10 dB. It has two working modes. The Boost mode uses a first - order minimum - phase low - pass filter to enhance and extend the low frequencies in a stereo setup. The LFE mode activates a fourth - order low - pass filter with selectable settings of 80 Hz or 120 Hz, which is suitable for enhancing the low - frequency effects channel in a surround sound system. It is also equipped with a low - pass filter (LPF) control to optimize the subwoofer's response according to the acoustic characteristics of the room.
