In this review, we will be comparing Focus 10 and LSX, two Powered Bookshelf speakers from Dynaudio 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 Dynaudio Focus 10 and KEF LSX 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 Dynaudio Focus 10 and KEF LSX 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.
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 Dynaudio Focus 10's and KEF LSX's external dimensions. Dynaudio Focus 10 has external dimensions of 315.0 x 180.0 x 261.0mm ( 12-3/8-inch x 7-1/8-inch x 10-1/4-inch) whereas KEF LSX has external dimensions of 239.7 x 155.6 x 180mm ( 9.4375 x 6.125 x 7.1inch) .
Dynaudio Focus 10 is clearly the larger of the two speakers. Its body is 24.4mm wider, 75.3mm taller and 81mm deeper than KEF LSX.
Below you can see the front view size comparison of Dynaudio Focus 10 and KEF LSX 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 Dynaudio Focus 10 is approximately 469.8cm2 / 72.8inch2 and base area of the KEF LSX is approximately 365.7cm2 / 56.7inch2. The Focus 10 requires 28% more surface area than the LSX 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 Dynaudio Focus 10 weighs 7.50kg / 16.5lbs and the KEF LSX weighs 3.50kg / 7.7lbs. This makes the Focus 10 114% heavier than the LSX.
