The SVS PB17 Ultra Subwoofer supersedes the PB16 Ultra. Among the features are a colossal 17″ dual voice coil woofer and two mono Class D amplifiers. Besides, the Base driver is big and robust enough to absorb the high power input from the amplifier.
SVS PB17 Ultra Subwoofer
It is worth mentioning that a very efficient switch mode power supply chosen for the unit is less burden the home’s mains supply. In fact, the sophisticated DSP engine runs at the command of a dedicated app. Finally, there are inputs of balanced XLR along with the standard RCA connectors.
Very Low Frequecy Response
The 17” glass fibre cone of the SVS PB17 Ultra Subwoofer’s woofer is impressive in size. In addition, the cone is powered by a so large 55lb toroidal ferrite magnet motor assembly.
Such a combination not only results in a huge amount of bass but also in the ability of the sub to behave accurately and delicately. The frequency band extends down to a jaw dropping 13Hz. Some instruments can produce notes as low as 13 Hz, usually organs and tubas. Moreover, there are special effects like explosions that can have such deep bass notes.
Advanced DSP
The SVS PB17 Ultra Subwoofer is equipped with a high-end Digital Signal Processor (DSP). The package is a 295 Mhz Analog Devices Chip set which is the most advanced ever to be used in a domestic product..
Control App
In order to operate the DSP of SVS PB17 Ultra Subwoofer an SVS subwoofer control app is provided. You can download the app on your smartphone or tablet and it has a wide range of features.
Besides, a six-channel parametric equalizer, a low-pass filter, and a phase control are included. The app can also be used to adjust the volume. Finally, with an update, the feature of auto room EQ is also enabled.
Dual Mono Amplifier
Enough power is supplied by that each voice coil gets it own Class D amplifier. By using this dual mono system the load on the house’s mains supply is reduced. Class D can reach an efficiency of up to 90%, requires less power, and produces less heat than linear systems.
Fast-switching MOSET output transistors are employed. The output consists of a series of high-frequency pulses. Pulses that are close together result a higher output. Finally, the output stage employs a high pass filter to restore the driver audio.
Switch Mode Power Supply.
The SVS PB17 Ultra Subwoofer uses an efficient switch mode power supply. Switch mode supplies are the first choice of high-power systems as they have good regulation and can accommodate smaller transformers.
Switching the transformer at a high frequency less heat is produced and the transformer used is switched at a high frequency. Regulation is achieved by feeding back the control IC. Several secondary windings are utilized to generate the different voltages required by the subwoofer.
Features and Benefits
- Deep Bass Output: The speaker is capable of producing very powerful, intense bass which lifts the overall sound to another level of excitement.
- Visually Pleasing: It looks fantastic and goes with any home theatre decor.
- Advanced DSP: It enables audio to remain pristine and personalised right down to the user’s preference/customisation.
- Room-Filling Sound: A speaker with sufficient power to overcome the dimensions of the speaker thus can effectively cover a large space, having a high output and excellent sound dispersion.
Summary of the SVS PB17 Ultra Subwoofer
The DSP engine of the SVS PB17 Ultra Subwoofer can be managed using a SVS subwoofer control app. The app is compatible with smart phones and tablets and offers quite a number of features. Besides the six-channel parametric equalizer, the app also contains a low-pass filter and phase control.
Additionally, the app can be used to change the volume. Lastly, an auto room EQ feature is available for a software update.
Construction
For even more bass output, SVS PB17 Ultra Subwoofer is equipped with three 4” ports. This provision for more air flow. Besides, the cabinet is made of double-thick MDF with heavy bracing. This helps to minimize any resonance or rattles
