PSB SubSeries 100
Ultra-compact powered subwoofer for desktop systems and more
Our take on the PSB SubSeries 100 by Crutchfield's Dave Bar
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.

I was looking for a small footprint subwoofer to be used in a relatively small TV/music room with 2 Boston Acoustics bookshelf speakers and Boston Acoustics center channel speaker. After tweeking the sub settings on my Sony receiver a bit I'm one happy customer.

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.
