Bass Drivers

The bass driver pictured below serves as the foundation of the S- 3EX speaker system. The driver's strength is the result of the Aramid/Carbon composite material, originally created during the development of the S-1EX, that is used in its diaphragm. Pioneer's exclusive LDMC magnetic circuit technology has been incorporated in order to preserve linearity from low to high output levels and minimize distortion.

Bass Enclosure Construction

The unique form of the S-3EX is based upon logical necessity. In order to synchronize the arrival time of sound from the CST and the two bass drivers, each driver is mounted upon a baffle that serves to create a highly delicate curve known as the "precision curve" (see illustration below). Made of up to 100 mm thick MDF (Medium Density Fiberboard), this baffle is, moreover, strong enough to contain the force of the drivers. Additionally, the bass port has been carved out of an extremely thick block of MDF, resulting in the reduction of wind noise for clear, deep bass.

Crossover Networks

The crossover networks use only the finest components. Air cored coils, noninductive resistors, and film capacitors in the signal path are all carefully chosen and optimized for the CST driver to provide the greatest transparency to the signal. The bass drivers use silicon steel plate core inductors that minimize distortion and loss during energy transfer. All components are connected directly to their respective wiring materials, instead of a printed circuit-board, allowing for minimal loss and maximum performance.

Collaboration with Air Studios

Since its establishment by George Martin in 1969, London, England's Air Studios has earned unequivocal respect from scores of artists who recognize it as the world's premier recording studio. The Air Studios seal that was awarded to the S-3EX indicates that these speakers are capable of producing the high- quality sound demanded by the world's top-class sound creators.

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.
