SV Subwoofers

This disc allows the user to play 10Hz through 98Hz in one hertz increments allow- ing very good resolution over your measurements. Other good examples for test discs are Avia’s Guide to Home Theater and Digital Video Essentials. When meas- uring the room’s response use a minimum resolution of 5Hz. Figure 3 on the previ- ous page shows a theoretical illustration of a room’s response.

Before you plot your results however, it’s important to note the Radio Shack sound meter is not totally "linear" in its accuracy down low. All similar meters are off by the similar amount depending on the frequency; so while its sensitivity below 20Hz is not what it is at 50Hz, there is a simple way to compensate for this deficiency. It's called a compensation chart.

Simply look to the below frequencies and add the required decibels (dBs) at the fre- quency in question. So if your system seems to be measuring 70dBs with a 20Hz tone, then really it's putting out 77.5dBs. This is a VERY substantial difference, roughly TWICE the acoustical energy, requiring several times the amplifier power to achieve. You can see then how critical the below chart is if you are using your PEQ to even out or “flatten” the room response of your bass.

Add the following to your measurements:

10Hz add 20dBs 12Hz add 16.5dB 16Hz add 11.5dB 20Hz add 7.5dB 25Hz add 5dB 31.5Hz add 3dB 40Hz add 2.5dB 50Hz add 1.5dB 63Hz add 1.5dB 80Hz add 1.5dB 100Hz add 2dB 125Hz add .5dB

SVS PEQ Controls

Explanation of the controls. Now that we understand how to measure the room’s response the next step is to correct the problem areas with the parametric equalizer. Before we start turning the controls we need to understand what the ad- justments are and how they work.

“Q”. This control determines how wide the correction will be. Each “hash mark” on the amp’s front plate represents 0.1 octave adjustments. The “HI” mark is equal to

0.1octave (narrow) and “LO” mark is equal to .9 octave (wide). In Figure 3 the highest peak is located at 40Hz and becomes flat again at 50Hz (the Highest Fre- quency of the peak). To determine the Q adjustment the following formula is needed. More on “Q” in a moment.

Formula 1 (Highest Frequency [X] – Center Point [Y]) Center Point (Y)

SVS PB2-Ultra specifications

The SV Sound SVS PB2-Ultra subwoofer is a powerhouse in the world of home audio, renowned for its exceptional performance and advanced engineering. Designed to deliver deep, impactful bass, it caters to audiophiles and home theater enthusiasts alike, establishing itself as a reference point in the realm of subwoofers.

At the heart of the PB2-Ultra is its formidable 12-inch driver, which utilizes a massive motor structure and a long-throw voice coil. This combination allows for impressive excursion capabilities, producing bass frequencies with remarkable clarity and authority. The driver is housed within a robust, ported enclosure that enhances its performance by maximizing the efficiency of airflow, resulting in deeper bass response.

One of the standout features of the SVS PB2-Ultra is its advanced dual driver design. With two active 12-inch drivers working in concert, the subwoofer is able to create an expansive soundstage and rich, immersive sound. The dual-driver configuration also helps to minimize distortion, enabling the subwoofer to reproduce intense low frequencies without losing detail.

Powering this impressive setup is a high-performance built-in amplifier that boasts a staggering output of 1200 watts RMS and 4000 watts peak. This substantial power reserve allows the PB2-Ultra to easily handle dynamic peaks, delivering a thunderous yet clean bass response, whether it's in the middle of a movie's action scene or during a music playback. The amplifier includes advanced software features for added flexibility, allowing users to fine-tune the subwoofer's performance to suit their listening environment.

Moreover, the PB2-Ultra is equipped with sophisticated tuning options. The subwoofer features adjustable phase control, variable low-pass filtering, and volume control, giving users the ability to achieve seamless integration with their main speakers. Additionally, the innovative SVS app allows for easy remote access to these settings, making it simple to adapt the subwoofer's performance on the fly.

Durability is another key characteristic of the PB2-Ultra. Constructed with high-quality materials and finishes, it not only looks elegant but is built to last. The stylish design allows it to fit seamlessly into various room decors, making it as visually appealing as it is functionally exceptional.

In summary, the SV Sound SVS PB2-Ultra is a high-quality subwoofer that combines advanced technology, powerful performance, and user-friendly features. Whether for a cinematic experience or music enjoyment, it stands at the forefront of subwoofer innovation, ensuring that listeners experience their audio in its fullest form.
