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 AM5 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 AM5's and Audioengine A5+ Wireless's external dimensions. PSB Alpha AM5 has external dimensions of 292.1 x 171.5 x 279.4mm ( 11.5 x 6.75 x 11inch) 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 15.9mm shorter and 31.8mm less deeper than PSB Alpha AM5 but it is also 11.1mm wider.
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 AM5 is approximately 479.2cm2 / 74.3inch2 and base area of the Audioengine A5+ Wireless is approximately 452.1cm2 / 70.1inch2. The Alpha AM5 requires 6% more surface area than the A5+ Wireless which gives it a small disadvantage 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 AM5 weighs 9.75kg / 21.5lbs and the Audioengine A5+ Wireless weighs 4.40kg / 9.7lbs. This makes the Alpha AM5 122% heavier than the A5+ Wireless.
