Little dog with big dog attitude

Shhhh, please don't tell the SubSeries 100 powered subwoofer just how tiny it is...it thinks it's big. And when you hear it, you'll think it's big, too. That's because PSB packed an amazing amount of muscle into this ultra-compact cube. Match it with PSB's Alpha PS1 powered speakers to create a pint-sized sound system that delivers serious, big-dog sound.

Bring your music, movies, and video games to life

PSB designed the SubSeries 100 to bring powerful bass performance to your desktop listening environment. This mighty mite even packs enough punch to fill smaller rooms. Its carefully engineered and computer-optimized 5-1/4" woofer is paired with an efficient, cool-running 50-watt Class D amplifier for tight, accurate low-frequency sound. You'll feel the rumble of explosions in your favorite Hollywood blockbusters and hear the crowds roar when you score a goal in your favorite game. It's great for music, too, like when you want to really hear the taut, tuneful sound of an upright acoustic bass from a classic jazz number.

Full-size controls and flexibility

The SubSeries 100 might be small, but it still gives you all the versatility of a full-sized subwoofer. You get an adjustable volume control, plus controls for setting the crossover frequency and inverting phase to ensure a perfect sonic match with your main speakers and your room. Rear-panel line level inputs accept both stereo preamp outputs and the mono subwoofer input from an A/V receiver or PSB's own Alpha PS1 powered speakers. The sub even comes equipped with a USB power port to charge and operate your compatible USB devices.

Product Highlights:

  • acoustic suspension (sealed) enclosure
  • 50-watt RMS amplifier
  • 5-1/4" front-firing polypropylene woofer
  • frequency response: 39-150 Hz (±3dB)
  • continuously variable 50-150 Hz crossover

  • line-level stereo RCA inputs
  • unfiltered LFE (Low Frequency Effects) mode for connection to a home theater receiver's subwoofer output
  • auto on/off
  • USB power port for charging compatible USB devices
  • 6-3/8"W x 6-3/8"H x 7-7/8"D
  • warranty: 5 years woofer, 1 year electronics
  • Our 60-day money-back guarantee

Why add a powered subwoofer?

A powered subwoofer gives you bass you can feel as well as hear. Our customers love the depth and impact their subs add to music and movies. We hear comments like "it brings out sounds I didn't know existed in discs I've watched a million times." Powered subwoofers aren't just for big bass that rattles your picture frames; they can also deliver tight, accurate lows. If you haven't shopped for a powered sub in a while, you might be surprised at how small they get. Look for an ultra-compact model if you want to tuck your sub away under an end table or in a corner.

Features

5.25" Woofer/50W Amp: A specially designed 5.25" long-throw polypropylene woofer is computer optimized to get the best bass extension and dynamic range without distortion. An innovative filter pole shifting technique is used to squeeze the maximum deep bass from the specially engineered driver unit. The acoustic suspension enclosure is extremely rugged and resonance-free assuring that only the desired bass frequencies are radiated into the room for clean articulate bass response. The efficient and cool running 50W (continuous) Class D amplifier is capable of 100W dynamic peak power and carefully matched to the driver. By matching the amplifier to the driver characteristics a synergy is achieved that boosts the level of performance far beyond what could be achieved otherwise.

Volume/Crossover/Phase Control: Along with adjustable volume, there are controls for setting the crossover frequency (50-150Hz) and inverting the phase (0°/180°) to facilitate a perfect and seamless integration between the full-range or satellite speakers you have partnered with the SubSeries 100 powered sub.

Note: Recommended settings for the SubSeries 100 when matched with the PSB Alpha PS1 Powered Speaker (760ALPHPS1, sold separately) are as follows - 0° phase, crossover half-way, and half volume (marked on sub). This combination creates an incredible micro-sized full range desktop system for your computer audio.

RCA/LFE Input: Line-level RCA inputs accept both stereo preamp outputs and the mono LFE channel input from an AV Receiver. Use the powered sub's Left RCA input for an LFE signal.

Auto On/Standby: When an audio signal is received by the SubSeries 100, the powered subwoofer turns on automatically. When no audio signal is detected, the sub's amplifier will automatically turn off after approximately 15 minutes.

PSB `00 subwoofr

Written By Bob H, Lake Monticello, VA on Thursday, July 10, 2014

Crutchfield Customer Review (What's this?)

I bought the PSB Alpha 1 speakers plus the audioquest USB attachment first. I should have bought the entire package at once, it is that good. Computer sound cards are not the best so adding the audioquest improved the sound. The Bose speakers were boomy so I replace them with the PSB 1s, but something was still missing. Good sound requires a base on which it can rest, and that base is a good low bass. While we may not pay much attention to the bass we notice it when it is missing. The entire system needed bass, so I added the PSB 100 subwoofer to the system and noticed an immediate improvement. Everything I played, whether off Youtube or through Netflix or the itunes on the computer sounded fuller, lusher and smoother. I cannot recommend the entire system too highly since it makes everything come alive. It is almost, but not quite, as good as the sound from a good 5.1 or 7.1 surround sound system. If you are tired of the speakers on your computer I suggest you buty the PSBs. You won't be sorry.

Pros: Works seamlessly throughout the spectrum of sound

Cons: Can't find a thing to complain about

PSB Sub 100

Written By Fred A, Silver Spring, MD on Tuesday, June 17, 2014

Crutchfield Customer Review (What's this?)

Blends seamlessly with the matching PSB Alpha S1 speakers. Does not call attention to itself as some subs do. Just rounds out the low end. Very nice!

Pros: Blends seamlessly with the Alpha. You can tweak it with dials if you want.

Cons: None

Small and punchy

Crutchfield Customer Review (What's this?)

For my use I give it a 5 star rating. I'm using it with audioengines A2+ Connected to my Mac Mini usb port. I have the crossover set on the sub at about 80hz. I had the unit on my desktop but the sound is better on the lower shelf of my cart. The build quility is solid and the finish is excellant. The performance for its size is amazing and adds a very solid foundation to the A2+. Play Bella Flecks Flight of the Cosmic Hippo and you'll understand the capability and sound quality of this sub. The only quirk that I notice is that I have to set the sub level at almost 3/4 volume. I don't know if this is due to the audioengines speaker outputs or the subs input resistance. Whatever the case, they are a perfect match. Instead of firing up my main home stereo system, I can sit and enjoy music at my computer desk sometimes for hours. BTW, the setup sound great for movies too.

Pros: Price, build quality and finish, compactness and most of all output and sound quality.

Cons: None for what it is.

Perfect addition

Crutchfield Customer Review (What's this?)

Bought this to compliment my PSB Alpha PS1 desktop speakers & could not be happier. It really fills in the sound, giving a rich complete sound stage. I can sit & listen for hours it's that good. This setup isn't going to fill a large room, but for a home office or desktop, it's gonna be hard to beat for sound quality. It's made me a PSB fan.

Pros: Sound; full, rich & warm. Amazing for it's size

Cons: A bit pricey

this is a wonderful product. has great sound.

The PSB 100 is a keeper.

Written By emailkenny, Benson, NC on Wednesday, January 22, 2014

Crutchfield Customer Review (What's this?)

Been up all night auditioning the PSB 100. So far, it's great. For now, I'm using it in a desktop PC and Audio-engine A2 configuration. I say, for now, because I'm going to replace the Audio-engine A2's as soon as I can, as they've become somewhat dated. Again, the PSB 100 is a definite keeper.

Pros: Solid sound and build quality. Compact design.

Cons: Piano black finish. Wish it came in a matte walnut or cherry finish.

The position of the sub isn't all that critical. I am using it with my home receiver and it provides plenty of bass for music and movies. It sits about 10 feet from the viewing area and there is still plenty of bass. I think under your desk will be just fine, it may need a little tweaking though to find the sweet spot. [ JOSHUA  Mar 13, 2014 ]
I have mine under a desk and it sounds great [ JONATHAN  Mar 11, 2014 ]
As far as making music, depends on your application. I'm using the PSB sub along with the PSB Alpha B1s, driven by a Meridian Explorer DAC directly from a PC. The Meridian Explorer is a fantastic DAC, plugs directly into one of my PC's USB ports, then connects to the PSB Alpha B1s via a 3.5mm to RCA interconnect (I'm using the AudioQuest Sydney interconnect). the Alpha B1s are powered speakers and sound fantastic in their own right. After I had them in place for a couple of weeks, I decided to add the PSB 100 sub. The sub itself is just great in this application, and filled out the bottom end very nicely. Understand this is a computer desktop system, and in that application the sound is very hard to beat. I've got a very high-end, dedicated two-channel system that this little desktop system rivals in terms of its musicality. I love listening to it while I work.The PSB Subseries 100 is a standard, powered sub that you feed signal to using a standard subwoofer interconnect. It is not USB powered nor can you use it in a USB application. The PSB Alpha B1s have a subwoofer out port that sends signal to the sub. So, in this application both the Alphas and the 100 sub are separately powered (standard 120V electrical connection).If you are thinking of using this sub in a dedicated two-channel set-up that's used for anything other than a desktop or very small room application, I don't think it will be a good solution, due to its diminutive size. But in my 10x13 study at home, this system works great and is amazingly musical. I think a lot of that is due to the quality of the Meridian DAC but the Sub 100 and the Alpha B1s work great together and are real winners as well.Hope this helps. [ STEVEN  Feb 01, 2014 ]
