PSB Audiophile Heritage
Over 50 Years of Excellence
PSB has been making speakers acclaimed for their value for over 50 years. The Alpha S10 continues this tradition, providing realistic sound for music and movies when paired with PSB speakers or any high-performance alternative.
Custom 10" Long-Throw Driver
Polypropylene Cone
The 10" driver features a durable polypropylene cone. Polypropylene is an ideal material for subwoofer drivers because it is lightweight and rigid.
Long-Throw
The long-throw driver allows for larger voice coil movement for greater air displacement. Long-throw is essential for deep, powerful bass.
Rubber Surround
The rubber surround provides a durable and flexible suspension. The rubber surround is superior to other suspensions because it is durable and maintains linearity.
Optimized Bass Reflex Enclosure
Internal Volume 1.45 cu ft (41 liters)
The 1.45 cu ft internal volume is optimized for flat bass response. Internal volume is critical for frequency response.
Bass Reflex Design
The bass reflex design uses a rear port to increase efficiency and bass extension. Bass reflex is ideal for compact subwoofers.
High-Efficiency Digital Amplifier
150W Continuous Power
The amplifier provides 150W of continuous power. Continuous power is the most important power measurement for audio.
210W Dynamic Power
The amplifier provides 210W of peak dynamic power. Dynamic power allows for handling musical signal peaks.
High Efficiency
The high-efficiency digital amplifier minimizes power consumption and heat generation. High efficiency is important for reliable operation.
Digital Signal Processing (DSP)
Flat Frequency Response
The DSP ensures flat frequency response across the entire operating band. Flat response is essential for accurate bass reproduction.
Robust Bass Extension
The DSP provides robust bass extension down to 28Hz at ±3dB. Bass extension is important for reproducing low-frequency content.
Performance Optimization
The DSP allows the PSB engineering team to optimize performance. DSP optimization ensures optimal performance under all conditions.
Variable Low-Pass Filter
50-150Hz Crossover Range
The variable low-pass filter allows for crossover adjustment between 50-150Hz. The adjustable crossover allows for optimal integration with main speakers.
LFE Setting
The Alpha S10 includes an LFE setting for low-frequency effects channels. The LFE setting is ideal for home theater.
Compact Rear-Vented Cabinet
Compact Dimensions
The cabinet measures 14" x 14 1/8" x 17 1/2" (356 x 359 x 445mm). The compact dimensions allow for flexible placement in any room.
Versatile Design
The rear-vented cabinet is versatile and adapts to any decor. The versatile design allows for placement in corners, along walls, or on the floor.
Woodgrain Finish
The woodgrain finish complements any room decor. The woodgrain finish is professional and attractive.
Rear Controls and Connectivity
Adjustable Volume
The rear volume control allows for level adjustment. The volume control is essential for integration with an audio system.
Adjustable Crossover
The rear crossover control allows for cutoff point adjustment. The adjustable crossover allows for optimal integration with main speakers.
Phase Switch
The phase switch allows for phase inversion to optimize integration. The phase switch is useful for phase alignment.
Low-Level Input
The RCA low-level input allows for connection to receivers and amplifiers. The low-level input is the industry standard.
AutoOn/Standby Switch
The AutoOn/Standby switch automatically turns on the subwoofer when it detects a signal. AutoOn/Standby saves energy.
Gold-Plated RCAs
The gold-plated RCAs provide superior quality connection. Gold plating resists corrosion and ensures clean signal transmission.
USB Power Jack for RT100
The USB power jack allows for connection of the RT100 wireless accessory. The wireless accessory provides wireless control.
Flexible Installation
Rubber Feet and Spikes
The Alpha S10 includes rubber feet and spikes for easy installation. Rubber feet are ideal for carpeted floors; spikes for wood floors.
