About Subwoofers

The design of virtually all loudspeakers involves compromises; and producing large amounts of undistorted low bass is often difficult (and expensive) to achieve in a full- range speaker. Most full-range speakers, therefore, simply aren’t designed to produce extended output at very low frequencies. This has historically been a limitation of high- end stereo speakers, and is often considered to be “an acceptable compromise” in many otherwise superb stereo systems; many audiophiles simply accepted that they weren’t going to hear the lowest octaves of a pipe organ or feel the solid punch of a drum with lifelike realism.

When home theater entered the scene, with its demand for the prodigious bass to accurately reproduce sound effects that you could actually feel, this limitation was addressed by including a separate speaker designed especially to produce only low bass; the subwoofer. The addition of a subwoofer simplifies the job of designing the other speakers, which no longer need to be totally full-range. It was also discovered that low frequencies (typically below 100 Hz) are virtually non-directional to the human ear, so a single subwoofer can provide the low frequencies for both channels in a stereo system or all channels in a multi-channel system.

In principle, it should be simple to design a subwoofer that can do a great job of producing the narrow range of frequencies required. Unfortunately many early subwoofers, while they did a good job of producing window-rattling explosions, dinosaur stomps, and subway crashes, didn’t sound very good with music. It turns out that it’s a lot easier to design a subwoofer that can make lots of earth-skaking bass if low distortion and smooth frequency response aren’t major concerns.

Now, however, as home theater listeners are coming to expect not only loud bass, but high quality bass, and audiophiles are starting to look for the same impressive bass performance from their stereo systems, but only if it sounds as good as the rest of their system, there is a need for subwoofers that can both rattle the floor and deliver extended low end with superb musicality.

Fortunately, advances in speaker technology, such as new cone and cabinet materials, more powerful and efficient amplifiers, and advanced DSP management systems, have made it possible to design a subwoofer that can deliver both thunderous special effects and superb musical performance. One of the leaders of this new generation of “super subs”, at home in both high-end home theater systems and audiophile stereo systems, are the new Emotiva X-Ref DSP Powered Subwoofers.

X-Ref 10 specifications

The Emotiva X-Ref 10 is a standout addition to the company's line of high-performance speakers, specifically designed for audiophiles looking to enhance their home audio experience. This floor-standing speaker embodies a perfect blend of advanced technology, premium materials, and meticulous engineering, making it an ideal choice for both music lovers and home theater enthusiasts.

One of the main features of the X-Ref 10 is its sophisticated 3-way design, which contributes to its impressive sound quality. This configuration includes a dedicated woofer, midrange driver, and high-frequency tweeter, each tasked with reproducing specific audio frequencies with precision. The 10-inch woofer delivers robust bass response, while the 4-inch midrange driver ensures clarity in the vocal and instrumental range. The 1-inch tweeter offers detailed highs, providing an expansive soundstage that captures every nuance of the audio.

Emotiva has employed advanced technologies in the X-Ref 10 to enhance its performance further. The use of a polypropylene cone for the woofer not only helps to minimize distortion but also improves overall responsiveness. The midrange and tweeter utilize a silk dome design, which allows for smoother frequency response and a more natural sound. Additionally, the speaker features a specially designed porting system that enhances low-frequency output while eliminating unwanted resonances.

The cabinet construction of the X-Ref 10 is another highlight. It is built from high-quality MDF for structural integrity and resonance control, ensuring that sound waves remain undistorted. The internal bracing is strategically placed to minimize vibration and enhance acoustic performance. Aesthetic appeal is also a priority, with a sleek and modern design available in elegant finishes that can complement any home décor.

Connectivity is simplified with the X-Ref 10, featuring robust binding posts that accept a variety of cable types and ensure a secure connection. The impedance is optimized for compatibility with a wide range of amplifiers, allowing for flexible system configurations.

With its excellent tonal balance, dynamic range, and attention to detail, the Emotiva X-Ref 10 is designed to provide an immersive listening experience. Whether used for critical music playback or as part of a surround sound setup, this speaker delivers audio performance that meets the high standards set by Emotiva. It represents a significant investment in sound quality that's sure to enhance any audio setup, making it a must-consider option in the competitive speaker market.
