PSB Alpha AM3 Compact Powered Speakers at Vinyl Sound Buffalo NY The PSB Alpha AM3 is PSB's most compact active powered speaker, delivering studio-quality stereo sound from a cabinet measuring just 5⅛" wide and 8⅝" tall — suited to desktop, bedroom, and small living room setups where space is limited without compromising on input versatility or sound quality. Available at Vinyl Sound in Buffalo, New York, the AM3 incorporates a built-in 35W × 2 RMS amplifier, a ¾" aluminum dome tweeter with ferrofluid and neodymium magnet, and a 4" cone woofer with rubber surround in a bass reflex MDF cabinet. Frequency response measures 56Hz to 22kHz (±3dB) with an LF cutoff of 40Hz (−10dB). Inputs include 3.5mm analog, phono MM (RCA) for direct turntable connection, optical digital, USB, and Qualcomm aptX Bluetooth, matching the full input suite of the larger Alpha AM5. The AM3 is available in Matte Black and Matte White and is part of Vinyl Sound Buffalo's full speaker collection, which includes powered, bookshelf, and floorstanding speakers from leading audiophile brands. Inputs, Connectivity, and DSP Performance Despite its compact dimensions, the PSB Alpha AM3 offers the same comprehensive input suite as the larger AM5. The phono MM input (RCA) accepts a direct turntable connection without a separate phono preamplifier, making the AM3 a self-contained and compact vinyl listening system. The optical digital input connects to televisions and CD players, while USB supports computer audio. Qualcomm aptX Bluetooth enables wireless streaming from smartphones, tablets, and computers with higher audio quality than standard SBC Bluetooth. A subwoofer output is available to extend bass when paired with an external subwoofer. PSB's DSP processing, developed in partnership with sister brands and informed by nearly 50 years of acoustic research at the Canadian National Research Council, optimizes frequency response, bass extension, and output for the AM3's driver complement and cabinet volume. Cabinet Construction and Design The Alpha AM3 cabinet is constructed from MDF with a vinyl sleeve finish and MDF front baffle, with perforated metal grilles attaching magnetically for tool-free removal. The compact bass reflex enclosure extends low-frequency output to 40Hz at −10dB from the 4" woofer, and DSP tuning ensures consistent near-field performance at desktop listening distances. The AM3 is available in Matte Black and Matte White finishes designed to suit desktop and shelf placement in any room decor. At 10 lbs net weight per pair, the AM3 is one of the lightest and most portable powered speakers in PSB's lineup.

The PSB Alpha AM3 and AM5 share the same input suite — 3.5mm, phono MM, optical, USB, and aptX Bluetooth — and the same overall design philosophy, but differ in driver size, amplifier power, and cabinet dimensions. The AM5 uses a 5¼" woofer and 50W × 2 amplifier in a cabinet measuring 6¾" × 11⅖", while the AM3 uses a 4" woofer and 35W × 2 amplifier in a more compact 5⅛" × 8⅝" cabinet. The AM3 is better suited to desktop and small room use, while the AM5 delivers higher output and deeper bass for larger spaces. Does the PSB Alpha AM3 need a separate amplifier? No. The Alpha AM3 is a powered speaker with a built-in 35W × 2 RMS amplifier and connects directly to turntables, TVs, computers, and smartphones without a separate amplifier or receiver. It is a complete self-contained audio system requiring only a power connection and a source device. Can I connect a turntable directly to the PSB Alpha AM3? Yes. The AM3 includes a dedicated phono MM input (RCA) that accepts a direct connection from any turntable with a moving-magnet cartridge, without requiring a separate phono preamplifier. Turntables with a built-in phono preamp can connect via the 3.5mm analog input instead. Does the PSB Alpha AM3 support Bluetooth streaming? Yes. The Alpha AM3 supports Qualcomm aptX Bluetooth for wireless streaming from smartphones, tablets, and computers. aptX provides higher audio quality and lower latency than standard SBC Bluetooth and is compatible with most Android devices and Windows computers. iOS devices connect via standard AAC Bluetooth. Can I add a subwoofer to the PSB Alpha AM3? Yes. The AM3 includes a subwoofer output for connecting an external powered subwoofer, extending bass below the AM3's 56Hz (±3dB) lower limit. This allows the AM3 to serve as the satellite speaker section of a 2.1 desktop system when additional bass output is needed. Is the PSB Alpha AM3 good for desktop use? Yes. At 5⅛" wide and 8⅝" tall, the Alpha AM3 is one of the most compact powered speakers available from PSB and is specifically suited to desktop placement. PSB's DSP processing tunes the AM3's frequency response for near-field listening distances typical of desktop use, and the aptX Bluetooth and USB inputs make connection to a computer straightforward without cable clutter.
