In this review, we will be comparing LSX II and EGG, two Powered Bookshelf speakers by 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 KEF LSX II and KEF EGG 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 KEF LSX II and KEF EGG compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

LSX II has a frequency range of 54-28k Hz whereas EGG has a frequency range of 90-33k Hz. With a minimum frequency of 54Hz, the LSX II can go significantly deeper on the low side and provide stronger bass compared to the EGG's min frequency of 90Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Bookshelf class in our database.
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.
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 KEF LSX II's and KEF EGG's external dimensions. KEF LSX II has external dimensions of 240 × 155 × 180 mm ( 9.5 × 6.1 × 7.1 inch) whereas KEF EGG has external dimensions of 274.6 x 138.1 x 184.1mm ( 10.8125 x 5.4375 x 7.25inch) .
KEF LSX II is 34.6mm shorter and 4.1mm less deeper than KEF EGG but it is also 16.9mm 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 KEF LSX II is approximately 279.0cm2 / 43.2inch2 and base area of the KEF EGG is approximately 254.2cm2 / 39.4inch2. The LSX II requires 10% more surface area than the EGG which gives it a small disadvantage on placement in tight spaces.
