PSB Alpha S10 Subwoofer 10"

PSB Alpha S10 10" Powered Subwoofer at Vinyl Sound Buffalo NY

The PSB Alpha S10 is a 10" powered subwoofer from PSB's Alpha Series, delivering deep bass extension for both music and home theatre applications through a 150W continuous (210W dynamic peak) high-efficiency digital amplifier and a custom 10" long-throw polypropylene cone woofer in a tuned bass reflex enclosure. Available at Vinyl Sound in Buffalo, New York, the S10 measures 28Hz to 150Hz (±3dB) with an LF cutoff of 22Hz (−10dB), providing genuine subwoofer-range bass suited to pairing with PSB Alpha Series speakers or any high-performance bookshelf or tower loudspeaker system. DSP processing enables a flat frequency response and robust bass extension tuned by PSB's engineering team. The rear panel provides volume and crossover controls, a variable 50–150Hz low-pass filter with LFE bypass setting, phase switch, low-level RCA inputs, AutoOn/Standby switching, and a USB power jack for the optional RT100 wireless receiver accessory. Rubber bumpers and spikes are included for placement on hardwood or carpeted floors. The Alpha S10 is part of Vinyl Sound Buffalo's full speaker collection, which includes subwoofers, bookshelf, floorstanding, and centre channel speakers from leading audiophile brands.

Amplifier, DSP, and Driver Technology

The PSB Alpha S10 uses a custom 10" long-throw driver with a polypropylene cone and rubber surround, optimized for the S10's 1.45 cubic foot (41-liter) bass reflex enclosure. The built-in high-efficiency digital amplifier delivers 150 watts continuous and 210 watts dynamic peak power, providing sufficient headroom for both music transients and home theatre low-frequency effects. Digital signal processing (DSP) is used to tune the S10's frequency response for a flat output curve and extended bass to 22Hz at −10dB — a specification typically associated with larger and more expensive subwoofers. The variable low-pass crossover filter, adjustable from 50Hz to 150Hz, allows precise integration with the satellite speakers regardless of their bass rolloff point, and the LFE bypass setting passes the full .1 channel signal from an AV receiver without additional filtering.

Controls, Connectivity, and Placement

All controls on the Alpha S10 are rear-panel mounted, including the volume control, variable crossover (50–150Hz), phase switch, LFE setting, and AutoOn/Standby switch. Low-level RCA inputs accept a signal from an AV receiver's subwoofer pre-output or from a stereo amplifier's line-level output. Gold-plated RCA connectors are used throughout. The USB power jack on the rear panel supports the optional PSB RT100 wireless receiver accessory, enabling wireless connection from a compatible transmitter and eliminating the need to run a subwoofer cable across the room. Rubber bumpers are supplied for hardwood and tile floors, and carpet spikes are included for carpeted surfaces.

Frequently Asked Questions

Which PSB speakers does the Alpha S10 pair with?

The PSB Alpha S10 is designed to integrate with any PSB Alpha Series speaker system, including the Alpha T20 tower speakers, Alpha P5 and P3 bookshelf speakers, and Alpha C10 centre channel, forming a complete Alpha Series 2.1 or 5.1 home theatre system. The S10's variable crossover (50–150Hz) allows it to be set below any satellite speaker's bass rolloff point for seamless integration. The S10 is also compatible with non-PSB bookshelf and tower speakers that benefit from additional bass reinforcement.

How low does the PSB Alpha S10 play?

The PSB Alpha S10 measures 28Hz to 150Hz at ±3dB and has a measured LF cutoff of 22Hz at −10dB. This extension is achieved through the combination of a custom 10" long-throw driver, a tuned 1.45 cubic foot bass reflex enclosure, and DSP processing tuned by PSB's engineering team. A 22Hz LF cutoff covers the full range of audible bass content in music and home theatre, including the lowest organ notes, bass guitar fundamentals, and cinema low-frequency effects.

Can the PSB Alpha S10 be used wirelessly?

Yes, with the optional PSB RT100 wireless receiver accessory. The S10 includes a USB power jack on its rear panel specifically for the RT100, which pairs with a compatible wireless transmitter connected to the AV receiver or amplifier's subwoofer output. This allows the S10 to be placed anywhere in the room without running a subwoofer cable. The RT100 wireless accessory is sold separately and is available through Vinyl Sound Buffalo.

What is the LFE setting on the PSB Alpha S10?

The LFE (Low Frequency Effects) setting bypasses the S10's internal variable low-pass crossover filter when connected to a dedicated subwoofer output (.1 channel) from an AV receiver. Most AV receivers apply their own bass management crossover to the subwoofer output, so bypassing the S10's internal filter avoids double-filtering and preserves the AV receiver's crossover settings. When connected to a stereo amplifier's line-level output without bass management, the variable crossover control is used instead.

Where should I place the PSB Alpha S10 in my room?

The PSB Alpha S10's compact rear-ported cabinet is designed for flexible room placement. Common positions include a corner (which reinforces bass output), along the front wall between the main speakers, or to the side of the listening area. The phase switch and variable crossover controls allow the S10's output to be adjusted to suit different placement positions and room acoustics. Rubber bumpers are supplied for hardwood and tile floors, and carpet spikes are included for carpet placement.

Can I use the PSB Alpha S10 for music as well as home theatre?

Yes. The Alpha S10's DSP-tuned flat frequency response and 28Hz bass extension make it well suited to both music and home theatre use. For music listening, setting the crossover to match the satellite speakers' rolloff point (typically 60–80Hz for bookshelf speakers) allows the S10 to extend bass without audibly localizing the subwoofer. PSB designed the S10 specifically to work with both music and movie content, continuing the Alpha Series tradition of high-value, versatile audio performance.
