SVS Ultra Bookshelf Speakers Gloss Black

Product Information

At 1 kHz and 90 dB SPL, THD was 0.67%. Note that for speakers, I now use just THD rather than THD+N since there is at least 30 dB of room noise. The 3rd and 5th harmonics are larger than the 2nd and 4th

be around 50Hz based on this measurement and the impedance measurement. I confirmed SVS’s sensitivity rating of 87dB Pristine Sound Quality: Results in a smooth balance of low, mid, and high-frequency audio for a dynamic listening experience.The following tests are conducted at (4) approximate equivalent output volumes: 70/79/87/96dB @ 1 meter. The (4) voltages listed in the legend result in these SPL values. The aluminum dome tweeter never sounded metallic, nor exhibited any unpleasant frequency-specific resonances. However, it did have a tendency to sound bright with modern pop and electronic music. Sometimes this comes with the territory of a revealing metal-dome tweeter, and is a tradeoff for the level of insight they offer. The treble is prominently showcased; this isn’t a speaker that’s forgiving of inferior source material. Soundstage width is about ±70° until about 10kHz which is typical for a design like this (dome tweeter on a flat baffle). There are a variety of available bookshelf speakers. Some help enhance your viewing experience, and there are bookshelf speakers that can make music sound better.

Acoustic Cabinet Design: The rigid and braced cabinet minimizes resonances and non-linearities for a clean and engaging output. SVS Ultra Bookshelf has a frequency range of 45 hertz to 32 kilohertz, whereas KEF LS50 has a broader range at 47 hertz to 45 kilohertz. SVS Ultra Bookshelf speakers are bigger at 15 by 8.5 by 10.9 inches (381 by 216 by 277 millimeters), whereas KEF LS50, which measures 11.9 by 7.9 by 11 inches (302 by 200 by 280.5 millimeters). These dimensions mean that you can put the LS50 in more room configurations than the SVS Ultra. The purpose of this test is to illustrate how much (if at all) the output changes as a speaker’s components temperature increases (i.e., voice coils, crossover components) instantaneously. I used over 800 measurement point which was sufficient to compute the sound field of the speaker. Measurement axis is the tweeter center.

Product highlights:

Meanwhile, the midrange drivers measure 6.5 inches (165 millimeters) and are made with a glass and fiber cone. These drivers are stiff and sensitive and have aluminum shorting rings that don’t allow for distortion.

Crossover frequency and slopes optimized for excellent off-axis polar response, outstanding phase coherency, and total radiated sound power The Ultra Bookshelf speakers represent an uncompromising approach to loudspeaker design. From the drivers and crossover to the build materials and cabinet design, every element is painstakingly engineered and tested to achieve reference sound quality. Ultra Driver & Tweeter Design Having looked at the measurements first before listening, I thought they would either sound good "out of the box" or do so with just a bit of EQ. That did not happen. Try as I did, I could not like the sound with or without EQ. Yes, I could see the appeal of boosted upper bass in giving "warmth" to the speaker. But too much of that was well, too much of a good thing. I am puzzled where the sharpness was coming from seeing how I could not tame it. Perhaps directivity error was causing this. No expense was spared with the innovative SVS SoundMatch two-way crossover. The unique topology creates a broad, yet focused and precise soundstage, with accurate frequency response and imaging at all listening positions. The precise tuning of the SoundMatch Crossover also ensures balanced output from sparkling highs to the crystal clear and commanding midrange, down to visceral and authoritative bass. Performance Driven Cabinet Design and Geometry SVS begins the speaker design process with extensive computer modeling, which helps them zero in on the right driver, crossover, and cabinet characteristics. Then, like other world-class speaker companies, they test each design in an anechoic chamber, which eliminates the effects of room reflections, to ensure highly accurate measurements.

Features

The Frequency Response derived from an Impulse Response is shown below. The volume level was set to approximately 87 dB SPL. The IR-derived response greatly reduces the effects of the room. The response is reasonably flat (no slope from one end to the other). The peak above 20 kHz is the metal tweeter cone resonating. It is out of the range of human hearing and is common in metal tweeters. much to like about these speakers and so little to complain about. They offer a very balanced sound, with great
