Bi-Amplification Connections

Bi-Amplification allows the best performance when using dedicated amplifiers for low- and mid-to-high-frequency sections. There are two possible configurations, commonly referred to as horizontal and vertical bi-amping.

Caution

Remove the shorting links before connecting speaker cables in bi-amplifications connections. Failure to do so may result in damage to your amplifiers.

Vertical Bi-Amping

With this configuration, identical stereo amplifiers are used for each speaker system. One channel of each amplifier drives the low frequency section and the other channel drives the high frequency section, as shown below.

Connect one set of wires and amplifier channel to the bottom set of binding posts (bass driver-specific network).

Then connect a second set of wires and the other amplifier channel to the top binding posts (CST-specific network).

Take care to connect both (+) wires to the (+) amplifier terminals and both (–) wires to the (–) amplifier terminals.

Horizontal Bi-Amping

With this configuration, you may use different stereo amplifiers for the low- and mid-to-high-frequency sections of the speaker system (e.g., tube amplifiers for high frequency and solid state for low frequency). Each channel of one amplifier drives the low- frequency section of each speaker system and each channel of the other amplifier drives the mid-to-high-frequency section, as shown below.

This method requires that both amplifiers have the same gain; otherwise an imbalance will be heard between the low- and mid- to-high-frequency reproduction from the speaker system. If in doubt, please consult your local dealer.

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.
