Passive bi-amping your X-Ref speakers

Bi-amping is when you use separate amplifiers to power the high-frequency and low-frequency section of each loudspeaker. Most listeners agree that bi-amping produces a significant improvement in sound quality. Because the load on each amplifier is reduced, and both the amplification and the high-current signal paths for the high-frequencies and low-frequencies are kept entirely separate, the result is cleaner sound. The X-Ref series speakers permit passive bi-amping, which means that the passive crossover for each section of the speaker remains in-circuit, and no line-level crossover is required between the preamp and power amps.

Implementing passive bi-amping for one pair of X-Ref speakers requires either two stereo amplifiers or four mono-block amps. For each loudspeaker, remove the

bi-amp terminal links on the input plate (shown in the figures on pages 7 and 16), connect one power amp channel to the high-frequency section, and another to the low-frequency section. Connect both power amp channels for each speaker to the same audio input signal (if the preamp doesn’t have dual outputs, a simple passive splitter can be used).

If four separate mono-block power amps are used, or if two stereo amps are used, it is generally recommended that they all be the same. Other configurations (some using different amps) are possible, but they are beyond the scope of this manual. If you have specific questions about various options, Emotiva Technical Support will be glad to help you.

Caution: Be sure to remove the bi-amp terminal links from the input terminals of the speakers when using your X-Ref speakers in a bi-amplified configuration. Failure to do so will PROBABLY result in damage to one or both amplifiers.

Note: When implementing passive bi-amping on a system with bass management, DO NOT use the bass management feature of your preamp or pre/processor to divide the audio spectrum between your bi-amp power amps; both power amps for each speaker should receive THE SAME AUDIO SIGNAL.

(In a system without a subwoofer, both amps should receive the same full-range signal; in a system with bass management that includes a subwoofer, the subwoofer will receive the low-pass filtered output and BOTH power amp channels for each speaker will receive the same high-pass filtered signal intended for the “main” speaker for that channel).

X-Ref specifications

Emotiva has long been synonymous with high-quality audio equipment, and the Emotiva X-Ref series continues this tradition with exceptional sound performance and cutting-edge technology. The X-Ref series is designed for audiophiles who demand the best in both functionality and aesthetics.

At the heart of the X-Ref series is its commitment to delivering an immersive listening experience. Each speaker in the lineup features proprietary drivers that have been engineered for high efficiency and extraordinary clarity. The midrange drivers utilize a woven composite material to reduce distortion, providing a natural and smooth vocal reproduction. Additionally, the high-frequency drivers are meticulously crafted to ensure precise sound staging and detail, allowing listeners to hear every nuance in their favorite recordings.

One of the standout features of the X-Ref series is its advanced waveguide technology. This innovation allows for optimal dispersion of sound, resulting in a wider sweet spot and improved imaging. Whether you are seated directly in front of the speaker or off to the side, you can expect consistent sound quality and an accurate representation of your music.

The build quality of the X-Ref speakers is equally impressive. Each cabinet is constructed from high-density MDF to minimize resonance. The elegantly designed enclosures not only look stunning but are also acoustically optimized to enhance performance. The striking finish options, including high-gloss and matte surfaces, allow these speakers to blend seamlessly into any home décor.

Connectivity is another area where the X-Ref series excels. With bi-wire and bi-amp capabilities, users can customize their audio setup to their preferences. The included terminals accept various cable types, ensuring compatibility with a wide range of audio systems.

Emotiva's dedication to performance extends beyond hardware; the X-Ref series also incorporates sophisticated crossover networks that utilize high-quality components. These crossovers ensure that each driver receives the correct frequency range, leading to a cohesive and balanced sound.

In summary, the Emotiva X-Ref series embodies the company's commitment to high-performance audio. With advanced driver technology, waveguide design, thoughtful construction, and user-friendly connectivity options, these speakers are sure to satisfy even the most discerning audio enthusiasts. Whether you are an avid music lover or a home theater aficionado, the X-Ref series is engineered to elevate your listening experience to new heights.
