SOUND QUALITY REVIEW（音色评测）:🤩
- Clear highs with a slightly recessed midrange, offering smooth sound.
- Tight bass with a deep low-end for its size, but may not be deep enough depending on room placement.
- Excellent clarity in treble, although slightly less defined than more expensive models.
- Full-range sound with a warm midrange and a slightly bright character.
- Very forgiving and musical, offering a natural presentation without coloring the sound.
- Performs well with a wide range of music styles, from rock to classical.
- Requires a dynamic amplifier for optimal performance and works particularly well with Rotel amps.
- Soundstage is impressive, providing a more immersive experience, especially with modest amplification.
- Requires proper placement (away from walls) for best sound performance.

- 高音清晰，中频略微凹陷，音质平滑。
- 低音紧凑，尺寸适中的低频表现不错，但根据房间摆放位置可能无法达到更深的低音。
- 高音清晰明亮，虽然与更昂贵的型号相比略显不够细腻。
- 全频表现，温暖的中频和稍微明亮的音色。
- 音质宽容且富有音乐感，呈现自然声音，不会过多修饰。
- 能很好地表现各种音乐风格，从摇滚到古典。
- 需要动态放大器才能发挥最佳表现，尤其与Rotel功放配合效果尤佳。
- 声音舞台表现出色，尤其在使用适度的放大器时，提供更具沉浸感的体验。
- 需要正确的摆放（远离墙壁）以获得最佳声音效果。

DESIGN & TECHNOLOGY 设计与科技:
- The CM4 is a 3-way floor-standing speaker with a choice of real wood veneers (Maple and Rosenut) and a brushed aluminium baffle for a modern design.
- Slim design provides extra bass extension and better resolution of fine details, capable of reaching higher output levels for larger rooms.
- Tube loading technology used for the tweeter enhances absorption of unwanted radiation from the rear of the diaphragm, resulting in a more focused and natural high-frequency sound.
- The bass unit is made from aluminium for stiffness and piston-like performance.
- Twin Flowports at the rear feature dimpled surfaces to smooth airflow and reduce turbulence, designed using golf ball aerodynamics theory.
- The lower Flowport is integrally moulded with the terminal tray.
- Nautilus Tweeter technology maintains focus and time-sensitive sound with exceptional stereo imaging and three-dimensional accuracy.
- Kevlar is used for the loudspeaker cones to reduce unwanted standing waves, a technology developed by B&W and originally created by DuPont for bulletproof vests.
- Flowport technology reduces distortion and chuffing noise, improving airflow and reducing compression at high sound levels.

- CM4 是一款3路落地扬声器，提供枫木和罗斯木两种实木贴面选择，配有拉丝铝合金音响面板，呈现现代化设计。
- 纤薄的设计提供了额外的低频延展和更好的细节解析能力，适用于较大的房间，可达到更高的输出水平。
- 高频单元采用管式加载技术，增强了对扬声器振膜背面不必要辐射的吸收，结果是产生更集中的自然高频声音。
- 低频单元采用铝制材料，具备良好的刚性和类似活塞的性能。
- 后部的双重 Flowport 采用凹槽表面，运用了高尔夫球气动学原理，能够平滑气流并减少气流湍流。
- 下部 Flowport 与端子托盘一体化成型。
- Nautilus 高频单元技术保持声音的集中和时域敏感性，提供无与伦比的立体声图像和三维精确度。
- 使用凯夫拉 作为扬声器音盆材料，减少不必要的驻波，这项技术由 B&W 开发，凯夫拉 最初由杜邦公司为防弹背心制造。
- Flowport 技术通过改善气流，减少失真和气流噪音，在高音量下降低了压缩感。
