In this review, we will be comparing R-51PM and EGG, two Powered Bookshelf speakers from Klipsch 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 Klipsch R-51PM 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 Klipsch R-51PM and KEF EGG compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

R-51PM features a 1.0" Aluminum LTS Tractrix Horn Tweeter and 1 x 5.25" Copper-spun IMG Woofer with a Crossover frequency at 1663Hz. On the other hand, the EGG features a 0.75" Aluminum Dome Tweeter and 1 x 4.25" Aluminum Woofer .
Frequency Response
R-51PM has a frequency range of 68-21k Hz whereas EGG has a frequency range of 90-33k Hz. With a minimum frequency of 68Hz, the R-51PM 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 Klipsch R-51PM's and KEF EGG's external dimensions. Klipsch R-51PM has external dimensions of 330.2 x 179.4 x 260.3mm ( 13 x 7.0625 x 10.25inch) whereas KEF EGG has external dimensions of 274.6 x 138.1 x 184.1mm ( 10.8125 x 5.4375 x 7.25inch) .
Klipsch R-51PM is clearly the larger of the two speakers. Its body is 41.3mm wider, 55.6mm taller and 76.2mm deeper than KEF EGG.
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 Klipsch R-51PM is approximately 467.0cm2 / 72.4inch2 and base area of the KEF EGG is approximately 254.2cm2 / 39.4inch2. The R-51PM requires 84% more surface area than the EGG which gives it a small disadvantage on placement in tight spaces.
