In this review, we will be comparing Alpha AM5 and The Fives, two Powered Bookshelf speakers from PSB and Klipsch. Being Powered speakers, they both have built-in amplifiers so you don't need an external power amp or an integrated amp to power them. Let's have a brief look at the main features
of PSB Alpha AM5 and Klipsch The Fives first before getting into our more
detailed comparison.
In the following sections, we will get into more detail in order to better understand how the PSB Alpha AM5 and Klipsch The Fives compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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 The Fives 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 Klipsch The Fives'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 Klipsch The Fives has external dimensions of 314.3 x 165.1 x 282.6mm ( 12.375 x 6.5 x 11.125inch) .
PSB Alpha AM5 is 22.2mm shorter and 3.2mm less deeper than Klipsch The Fives but it is also 6.4mm wider.
Below you can see the front view size comparison of PSB Alpha AM5 and Klipsch The Fives in scale.

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 Klipsch The Fives is approximately 466.6cm2 / 72.3inch2. The Alpha AM5 requires 3% more surface area than the The Fives which gives it a small disadvantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 Klipsch The Fives weighs 4.85kg / 10.7lbs. This makes the Alpha AM5 101% heavier than the The Fives.
