In this review, we will be comparing Ai81 and LS60 Wireless, two Powered Floor-standing speakers from Fluance and KEF. 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 Fluance Ai81 and KEF LS60 Wireless 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 Fluance Ai81 and KEF LS60 Wireless compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Ai81 is a 2-way design whereas the LS60 Wireless is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Fluance Ai81 has external dimensions of 96 x 21.6 x 26 cm ( 37.8 x 8.50 x 10.24 inches) whereas KEF LS60 Wireless has external dimensions of 1090.0 x 212.0 x 394.0mm ( 42.9 x 8.3 x 15.5inch) .
Fluance Ai81 is 130mm shorter and 134mm less deeper than KEF LS60 Wireless but it is also 4mm 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 Fluance Ai81 is approximately 561.0cm2 / 87.0inch2 and base area of the KEF LS60 Wireless is approximately 835.3cm2 / 129.5inch2. The Ai81 requires 33% less surface area than the LS60 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 Fluance Ai81 weighs 13.16kg / 29lbs and the KEF LS60 Wireless weighs 31.20kg / 68.6lbs. This makes the LS60 Wireless 137% heavier than the Ai81.
