    One Subwoofer to Rule Them All. Introducing the PB16-Ultra.

    An unrelenting passion for breathtaking bass performance and engineering perfection guided every aspect of the PB16-Ultra subwoofer’s development. Ground breaking technology, rigorous design and extreme testing in real world and laboratory environments allowed SVS to achieve unmatched low frequency extension and output capabilities all while keeping it amazingly detailed and articulate. The culmination of all SVS design advancements, PB16-Ultra represents an incomparable bass experience. Nothing else comes close.

    Masterful Engineering. 3 Game-Changing Subwoofer Innovations.

    One of these ground breaking innovations would’ve been enough to make the PB16-Ultra an engineering tour-de-force, but the combination of 3 subwoofer firsts propels the SVS PB16-Ultra into the pantheon of all-time great audio products.

    Massive New 16-inch SVS Ultra Driver with Unprecedented 8-inch Edge Wound Voice Coil.

    When designing the biggest and most formidable driver ever used in an SVS subwoofer, it was of utmost importance to meet or exceed the same supreme standards of control and accuracy as every other subwoofer SVS manufactures. One huge advancement that allows the PB16-Ultra to handle the crushing force of a 16-inch driver is the 8-inch edge wound voice coil, the largest ever deployed in a consumer subwoofer. This innovation ensures ultra-low distortion and pinpoint control at the highest drive levels resulting in incredible output and low frequency extension. By nature, larger drivers are more difficult to control, but the unprecedented voice coil design ensures accuracy in frequency response and speed in transients without ever sounding boomy.

    Pushing the driver are four massive, dedicated toroidal ferrite magnets that unleash a staggering 95mm peak to peak excursion and the highest levels of motor force and palpable SPLs. The light and rigid 16-inch Ultra driver cone consists of a premium fiberglass resin composite with optimal stiffness to mass ratio to maximize movement of air and sonic energy without ever distorting or losing control.

    Stunningly Powerful, New Sledge Amplifier with Fully Discrete MOSFET Output and 1,500 Watts Continuous, 5,000+ Watts Peak Power.

    Conservatively rated at 1,500 watts continuous, 5,000+ watts peak power, the PB16-Ultra Sledge STA-1500D amplifier’s 64 Amp 200-Volt MOSFETs are the sonic muscle behind arguably the most powerful and highest fidelity subwoofer amplifier ever developed. Discrete MOSFET output unbridles the nearly limitless power in the Sledge amplifier and pushes the 16-inch driver to extreme levels of performance. They also represent an upgrade over the less robust integrated circuit output stages found in nearly all other Class D subwoofer amplifiers.

    Effortless power must be harnessed to ensure refined behaviour and pristine output at the most demanding drive levels. To achieve this, the PB16-Ultra subwoofer uses the audio industry’s most advanced 50 MHz Analog Devices Audio DSP with 56bit filtering to handle the nearly limitless power, only unleashing the perfect amount of low frequency energy at just the right time.

    Innovative New Smartphone App for Subwoofer DSP and Control.

    Compatible with Apple® and Android® platforms, the innovative PB16-Ultra smartphone app unleashes the full depth, force and nuance of the world’s finest subwoofer. The groundbreaking SVS subwoofer app controls all DSP functions and conveniently stores custom presets. It’s the easiest way ever to fine tune bass surpassing 16Hz at reference volumes from the comfort of your favorite seat.

    For added convenience, 2-way feedback shows updates in real time on both the app and subwoofer interface and Bluetooth connectivity allows adjustments to be made even when the subwoofer is not in sight. Control is also available via IR remote and an intuitive front panel display.

    Yes, bass frequencies are non-directional, unlike high frequencies. A subwoofer can technically be placed anywhere in a room, it is useful to experiment to find the best spot.

    Most home theatre subwoofers sold today are termed ‘Active Subwoofers’. These have an amplifier built into the cabinet along with the speaker driver/s. These need to connect to an AV Receiver or Stereo amplifier, usually with an RCA cable to the LFE or Subwoofer connection. ‘Passive’ subs are also available which require a separate amplifier to power the subwoofer driver.

    This is not ideal as it can cause the cabinet & its contents to rattle & vibrate. There are options which are vented with a grille attached to a tube which directs the sound from the subwoofer through the vent.

    This depends on your soundbar. Most Yamaha Soundbars have a wired subwoofer connection and therefore any active subwoofer will work. Some soundbars can only connect to a wireless subwoofer, please check with the manufacturer or owner’s manual to confirm.

    Yes, the quality of the subwoofer cable & connection will make a difference to the sound quality and depth of sound you will get from your sub. Ask one of the sales staff in store to recommend something appropriate.

    Most subwoofer calibration is done via your AV Receiver. Yamaha’s AVENTAGE range for example uses a system called YPAO with a microphone to measure the sound response in a room and adjust accordingly. Some subwoofers such as Bowers & Wilkins DB series can be further calibrated with a mobile device via their app.

    An active subwoofer has an amplifier built into the same box/cabinet as the subwoofer speaker driver. These typically plug straight into a wall power socket and an RCA cable from the AVR/Amp.

    A subwoofer technically can go anywhere in a room but in our experience it’s best to sit the primary sub at the front of the room, either in the centre or off to one side.

    This depends on the sub itself. If a sub is laid on its side, make sure it has some kind of isolation from the floor.

    Some subwoofers like the Sonos sub connect wirelessly to another Sonos soundbar or wireless speaker via wifi network. These still have their own amp built in and require a power connection.
