低频驱动器

下图所示低频驱动器是 S-3EX扬声器系统的基础。驱动器强度源 于其振膜所采用的聚酰胺 / 碳复合材料,该材料最初是在 S-1EX开发中得到的。为了保持由低到高输出电平的线性并将失真最小 化,采用了日本先锋公司专有 LDMC 磁路技术。

低频扬声器外壳构造

S-3EX的独特外形基于逻辑需要。为了让来自 CST 以及两个低频驱 动器的声音抵达时间同步,每个驱动器都安装在隔音板上,以便 产生称为 精密曲线的高度精确曲线 (参见下图)。此隔音板 由厚达 100 mm MDF (中密度纤维板)组成,其强度足够承担驱 动器的压力。另外,低频孔由很厚的 MDF 镂刻而成,以便降低风 噪声而得到清楚低沉的低频信号。

分频网络

分频网络完全采用优质零部件。信号线路中的空心线圈、无感电 阻、薄膜电容都进行了精心挑选和优化,以便 CST 驱动器产生更 好的信号透射度。低频驱动器采用硅钢片芯感应线圈,以便将能 量转换中的失真和损耗最小化。所有元件都直接连接到各自的布 线材料上,而不是采用印刷线路板,这样损耗最小而性能最佳。

Air Studios 的合作

自从 1969 年在伦敦由 George Martin 创办以来,英国 Air Studios 得到艺术家的明确推崇,被认为是世界上最好的录音室。授予 S- 3EX Air Studios 标志,表明这些扬声器可以产生满足世界上顶 级音响制作师需要的高品质声音。

S-3EX specifications

The Pioneer S-3EX stands out as a remarkable offering in the world of high-fidelity audio systems. Renowned for its impressive sound quality and dynamic performance, this speaker adeptly caters to audiophiles and casual listeners alike. The S-3EX is distinguished by its innovative technologies and thoughtful design, ensuring an exceptional listening experience across various genres.

One of the main features of the S-3EX is its unique construction that employs high-grade materials to facilitate superior sound reproduction. It is engineered with a robust cabinet designed to minimize resonance and vibrations, which can interfere with audio clarity. The cabinet's shape and internal bracing contribute to an optimal acoustic environment, delivering clear and rich sound.

The speaker utilizes a three-way design, incorporating a 1-inch soft dome tweeter, a 4-inch midrange driver, and two 8-inch woofers. This configuration allows for an extensive frequency response, ensuring detailed highs, articulate mids, and deep, powerful lows. The incorporation of dual woofers is particularly beneficial for bass-heavy music, providing a rich depth that enhances the overall listening experience.

One of the standout technologies featured in the S-3EX is Pioneer’s proprietary “Advanced Wide Dispersion” technology. This innovation ensures that sound is evenly distributed throughout the space, making it ideal for larger rooms or gatherings. Listeners can enjoy a consistent audio experience, regardless of their position in the room.

Additionally, the S-3EX benefits from Pioneer's “Natural Sound” philosophy, which aims to deliver music that accurately represents the original recording. This commitment to authenticity is realized through careful tuning and innovative engineering, making the S-3EX a true representation of Pioneer’s dedication to high-quality sound.

The sensitivity rating of the S-3EX is noteworthy, allowing for compatibility with a wide range of amplifiers and audio configurations. This versatility makes it an excellent choice for both dedicated audiophiles and those who may be exploring high-fidelity audio for the first time.

In summary, the Pioneer S-3EX combines exceptional build quality, innovative design, and advanced audio technologies to create a speaker that resonates with music lovers. Its three-way configuration, wide dispersion capabilities, and commitment to natural sound establish it as a standout choice in the high-fidelity speaker market, delivering an immersive audio experience that captivates and delights.
