Bi-wiring and passive bi-amping

Most X-Ref loudspeakers offer removable bi-amp terminal links. By removing these links, you can access the high-frequency and low-frequency sections of the speaker separately and take advantage of the improvements in sound quality offered by bi-wiring or passive bi-amping. Bi-wiring is when you use a single amplifier channel for each speaker, but run separate speaker wires from the amplifier to the high-frequency and low-frequency sections of the speaker. Bi-amping is when you use separate amplifiers to power the high-frequency and low-frequency section of each loudspeaker. Passive bi-amping 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.

Bi-wiring your X-Ref Series speakers

Many listeners hear an improvement in sound quality when bi-wiring their loudspeakers. This improvement is likely to be more significant when long or thin speaker wires are required, and is more noticeable with some speakers and amplifiers than with others.

In a normally connected loudspeaker, a relatively large amount of current flows into each section of the speaker (usually much more to the low-frequency section). Since this current all shares a single wire from the amplifier to the speaker, and speaker wire has a low but finite resistance, the current flowing to each section of the speaker produces a measurable voltage drop in the wire, which in turn modulates the overall signal in the wire. So, when there’s a lot of loud bass, it may modulate or distort the treble, and vice versa. Since the low-frequency portion of the speaker typically operates at much higher current levels than the high-frequency portion, yet distortion in the mid and high frequencies is typically more audible, the most common result is a noticeable muddying and blurring of critical midrange and high frequencies during heavy bass passages.

By providing separate paths for current flow from the amplifier to the high-frequency and low-frequency portions of the speaker, bi-wiring eliminates this interaction and the distortion it causes. While the differences may be subtle, bi-wiring is something that can be tried quite easily - and at minimal cost (as long as your speakers support it, all you need is a second set of speaker wires).

To bi-wire the X-Ref speakers, remove the bi-amp terminal links from the input plate on each speaker (shown in the figures on pages 7 and 16). Connect two sets of speaker wires to each amplifier output terminal, then connect one set to each pair of input terminals on the X-Ref speaker. Be sure that both sets of wires are connected “in phase” (the wires from the plus/red terminal on the amp to the plus/red terminals on both inputs of the speaker).

Note: 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-wired configuration. Failure to do so will negate any positive effects of bi-wiring, and may cause damage to one or both amplifiers if hooked up incorrectly.

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.
