None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.

Cabinet Type and Port Position

Both Alpha AM3 and A5+ Wireless have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.

If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.

Physical Specs

Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare PSB Alpha AM3's and Audioengine A5+ Wireless's external dimensions. PSB Alpha AM3 has external dimensions of 220.7 x 131.8 x 206.4mm ( 8.6875 x 5.1875 x 8.125inch) whereas Audioengine A5+ Wireless has external dimensions of 276.2 x 182.6 x 247.6mm ( 10.875 x 7.1875 x 9.75inch) .

Audioengine A5+ Wireless is clearly the larger of the two speakers. Its body is 50.8mm wider, 55.5mm taller and 41.2mm deeper than PSB Alpha AM3.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited. The base surface area of the PSB Alpha AM3 is approximately 272.0cm2 / 42.2inch2 and base area of the Audioengine A5+ Wireless is approximately 452.1cm2 / 70.1inch2. The Alpha AM3 requires 40% less surface area than the A5+ Wireless which gives it a small advantage on placement in tight spaces.

Weight Comparison

The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The PSB Alpha AM3 weighs 4.50kg / 9.9lbs and the Audioengine A5+ Wireless weighs 4.40kg / 9.7lbs. This makes the Alpha AM3 2% heavier than the A5+ Wireless.
