Product Description
The PSB Alpha AM3 is a pair of powered compact speakers that sets a new standard for entry-level powered speakers. Featuring a 3/4" ferrofluid-cooled aluminum dome tweeter with a neodymium magnet, a 4" woofer with a textured polypropylene cone and rubber surround, a built-in 35W x2 RMS amplifier, 56Hz-22kHz frequency response, aptX Bluetooth connectivity, a dedicated MM phono input for turntables, a USB input with an integrated DAC, a digital optical input, digital signal processing (DSP) for frequency optimization and bass extension, and a compact, versatile design available in matte black and matte white, the Alpha AM3 provides audiophile-quality audio reproduction for music, movies, and TV without the need for an external amplifier.
PSB's Audiophile Heritage
Nearly 50 Years of Research
The Alpha Series began in 1991 with the simple idea of creating affordable speakers focused purely on performance. Drawing on nearly 50 years of research conducted by the Canadian National Research Council, the Alphas are known as some of the most iconic speakers in the world and remain the benchmark for entry-level speakers today.
3/4" Ferrofluid-Cooled Aluminum Tweeter
Superior Quality Aluminum
The 3/4" aluminum tweeter provides clear and precise high-frequency reproduction. Aluminum is an ideal material for tweeters because it is rigid and lightweight.
Ferrofluid Cooling
Ferrofluid cools the tweeter voice coil, allowing for higher power handling without distortion. Ferrofluid is a major technological advancement in tweeter design.
Neodymium Magnet
The neodymium magnet provides a strong magnetic field for greater efficiency. Neodymium is superior to other magnetic materials.
4" Woofer with Textured Polypropylene Cone and Rubber Surround
Quality Cone
The 4" woofer provides mid and low-frequency reproduction. The 4" size is ideal for compact speakers.
Rubber Surround
The rubber surround provides durable and flexible suspension. The rubber surround maintains linearity and durability.
Steel Basket
The steel basket provides a rigid structure for the driver. The steel basket is superior to other materials.
Built-in 35W x2 RMS Amplifier
Compact Power
The built-in 35W x2 RMS amplifier provides enough power for near-field listening. The 35W power is ideal for desktops, bedrooms, and small rooms.
Class D Amplifier
The Class D amplifier is efficient and low-distortion. Class D amplification is modern technology for audio.
Flat Frequency Response
56Hz - 22kHz at ±3dB
The 56Hz-22kHz frequency response at ±3dB provides flat reproduction across the entire audio band. Flat response is essential for accurate reproduction.
LF Cutoff -10dB at 40Hz
The low-frequency cutoff at 40Hz provides bass extension. Bass extension is important for music reproduction.
Versatile Connectivity
aptX Bluetooth
Qualcomm aptX Bluetooth provides high-quality wireless streaming from mobile devices, computers, or TVs. aptX is superior to standard Bluetooth.
Dedicated MM Phono Input
The dedicated MM phono input allows for direct connection of turntables. The MM phono input is ideal for vinyl enthusiasts.
USB with Integrated DAC
The USB input with integrated DAC allows for connection to computers. The integrated DAC provides quality D/A conversion.
Digital Optical Input
The digital optical input allows for connection to receivers, TVs, and other digital equipment. Optical is ideal for long distances.
Digital Signal Processing (DSP)
Frequency Optimization
DSP optimizes frequency response and bass extension. DSP optimization ensures optimal performance.
Placement Flexibility
DSP allows the speakers to sound great regardless of where they are placed. Placement flexibility is important for near-field listening.
Compact and Versatile Design
Compact Size
The compact 5 1/8" x 8 5/8" x 6 7/8" size allows for flexible placement on desks, bookshelves, and tables. The compact size is ideal for limited spaces.
Available Finishes
The Alpha AM3s are available in matte black and matte white. The matte finishes are elegant and professional.
Detachable Magnetic Grilles
The acoustically transparent detachable magnetic grilles allow for customization. The detachable grilles allow you to change the appearance.
