SVS PB-4000

Powered subwoofer with app control (Black Ash)

  • 13-1/2″” front-firing woofer with three front-mounted ports
  • built-in 1,200-watt amplifier
  • frequency response: 16-200 Hz


Everything you need, nothing you don't. HDR and 4K is supported in pass thru. My 2 year old Yamaha didn't. Have it paired with a Polk 5.1 speaker system. Sounds good to me. The Sony automatic sound calibration seems to provide more bass than my old Yamaha's calibration (sounds better to me)

Explosive bass from subwoofer experts

It's no secret why SVS's diverse lineup of powered subwoofers is so popular with our customers. Their acclaimed subs offer staggering levels of bass in a variety of footprints and enclosures. The all-new PB-4000 continues the company's track record of high-end performance with impeccable build quality and expert-level sound-tweaking options.

Friendly heads-up: this sub is not for the faint of heart. I mean, just look at the thing — that trio of tunnel-sized ports on the front mean business. And at 153 pounds (!!), it's one of the largest and heaviest subs in SVS's lineup.

Outstanding for movies, music, and video game immersion
I have a checklist of features that I look for in an elite powered subwoofer. The first few — sonic realism, visceral ""oomph,"" room adaptability, and ease of control — are crucial components of performance. The PB-4000 checks off each of these boxes with ease.

This sub can produce crazy levels of bass, for sure. But it also offers impressive control for such a large, ported enclosure. Use the PB-4000 with confidence as part of a high-end stereo or home theater system.

SVS PB-4000 Powered subwoofer
You won't find any knobs or dials on the back of the PB-4000 (shown in gloss black). Instead, everything is controlled from a free app on your smartphone or tablet.

Goal number one: move a lot of air
I'll get into the more nuanced aspects of this sub in a moment. But first things first: the PB-4000's most notable trait is its sheer brute strength. Its heavily braced enclosure houses a massive 13-1/2"" woofer. This exceptionally large surface area means there's a ton of bass wave generation. And its ported box design means that the backward motion of the driver also contributes to wave creation, further reinforcing low-frequency extension.

This mammoth driver is powered by a 1200-watt RMS amplifier which allows it to produce commanding bass all the way down to 16 Hz (that's dipping into subsonic territory — bass you feel but can't hear).

Wireless control from your phone
You'll find the PB-4000 simple to operate and control. There's no reaching behind it to fumble with hard-to-see dials and switches. Instead, make settings changes right from the front-panel interface — or easier still, the included IR remote control.

You can also control this sub via a free app on your phone, which lets you select your room's layout, change audio settings, and switch modes right from your seat.

Bass tailored to your room
SVS knows that a sub's performance is largely determined by the acoustics of your room, and your subwoofer's position within it. Thankfully, this enormous sub (did I mention it weighs over 150 pounds?) doesn't have to be wrangled into a single ""sweet spot"" in your room. It offers a host of sound adjustments that let you get great sound wherever it's located.

Use the app to adjust crossover frequencies, parametric EQ settings, polarity, room gain, and other bass management functions. You can even save up to three groups of tailored settings as presets. These let you set up and switch between ""listening modes"" for a particular time of day or entertainment source. For instance, you can easily dial the bass down for nighttime listening.
