The SVS PB16-Ultra represents the pinnacle of audio engineering in the realm of subwoofers. This high-end subwoofer pushes the boundaries of low-frequency reproduction, delivering an immersive and visceral sound experience for home theater enthusiasts and the most demanding audiophiles.
A Powerhouse at the Heart of Your System
The PB16-Ultra is equipped with an impressive 16-inch (40 cm) driver featuring a massive 8-inch (20 cm) edge-wound voice coil. This unique configuration provides exceptional cone control, reducing distortion and enhancing bass precision, even at extreme sound levels. The driver’s motor utilizes four high-quality ferrite magnets and a dual shorting ring system to optimize performance and minimize distortion.
The integrated Sledge STA-1500D amplifier delivers a continuous power output of 1500 watts RMS, with dynamic peaks reaching up to 5000 watts. This colossal power reserve allows the PB16-Ultra to handle the most intense movie soundtracks or demanding music tracks without ever faltering.
Unmatched Acoustic Flexibility
The PB16-Ultra stands out for its acoustic versatility. Its front-firing port system offers three operating modes:
- Standard Mode (three ports open): Optimized for balanced response and maximum output.
- Extended Mode (two ports open): Prioritizes deep bass extension.
- Sealed Mode (all ports closed): Focuses on precision and transient speed.
This flexibility allows the subwoofer’s performance to be tailored to the room’s acoustics and the user’s personal preferences.
Cutting-Edge Technology for Precision
At the digital core of the PB16-Ultra is a 50 MHz Analog Devices DSP (Digital Signal Processor) with 56-bit double-precision filtering. This processing power ensures ultra-precise driver control and optimal frequency response management.
The dedicated smartphone app provides intuitive access to all subwoofer functions, including a three-band parametric equalizer. This interface allows users to fine-tune the PB16-Ultra’s response to perfectly match the room’s acoustics and personal taste.
Robust Design for Uncompromising Performance
The PB16-Ultra’s cabinet is meticulously constructed to eliminate any unwanted resonance. The double-thick MDF front panel and rigid internal bracing ensure an inert structure, even during the most intense passages. The three large-diameter (3.5-inch/8.9 cm) tuned ports minimize air turbulence and port noise, ensuring clean and distortion-free reproduction of the deepest bass.
Extended Frequency Range for Total Immersion
The PB16-Ultra pushes the boundaries of low-frequency reproduction. In standard mode, its frequency response ranges from 15 Hz to 280 Hz (±3 dB), delving deep into infrasonic territory. In extended mode, the subwoofer can even reach down to 13 Hz, delivering a physical bass experience that few systems can match.
This ability to reproduce the lowest frequencies allows the PB16-Ultra to faithfully render the most spectacular special effects in action movies while revealing the subtle nuances of low-frequency instruments in the most demanding music recordings.
Comprehensive Connectivity for Seamless Integration
The PB16-Ultra features stereo XLR and RCA inputs and outputs, ensuring optimal compatibility with high-end and professional audio systems. Its extended input voltage range allows seamless integration into a wide variety of setups.
The subwoofer also includes advanced features such as 12V trigger input and auto-standby mode, making it easy to integrate into home automation systems while optimizing energy consumption.

All the superlatives have already been used to describe this subwoofer. Impressive in every way. Faced with such an outpouring of power and control, I went and bought a second one. Two subs give you better bass consistency in the room—especially with a beast like this. Normally, you’re supposed to forget the sub is even there. Hard to do with this one given its size!

Tous les superlatifs ont déjà été utilisés pour qualifier ce caisson. Massif en tous points. Devant une telle débauche de puissance et de maîtrise, j’en ai pris un deuxième. Deux caissons amènent une meilleure cohérence des basses dans la pièce. À plus forte raison pour ce monstre. Normalement, il faut parvenir à oublier la présence du caisson. Difficile avec celui-là vue sa taille !

very imposing product in terms of size (height and depth), not to mention its weight
as for its function, nothing to complain about
it complements the SVS SB 16 Ultra already in place, which was perfectly fulfilling its role
I mainly listen to music, and they take their place among the speakers to enrich the sound
hard to describe their performance—out of the ordinary—but the bass is full and fast

produit tres imposant par sa taille (hauteur et profondeur) sans compter son poids
par rapport a sa fonction, rien a redire
il complete le SVS SB 16 ultra deja en place qui remplissait parfaitement sa mission
j ecoute essentiellement de la musique et ils trouvent leur place parmi les enceintes pour enrichir le son
difficile de decrire leurs performances, hors du commun mais les basses sont pleines et rapides

Just wanted to let you know that this subwoofer is a performance monster.
Powerful, smooth, fast.
In short, just perfect.
It's so good that I'm going to get another one.
A marvel.

Juste pour vous dire que ce caisson est un monstre de performance.
Fort doux rapide.
Bref juste comme il faut.
Il est tellement bien que je vais en prendre un autre.
Une merveille.
