In this review, we will be comparing Focus 20 XD and TSi100, two Bookshelf speakers from Dynaudio and Polk Audio. The main difference between these two speakers is that the Dynaudio Focus 20 XD is a Powered speaker which means that it has a built-in amplifier inside the speaker body so you don't need an external power amp or an integrated amp whereas the Polk TSi100 is a Passive speaker so has to be matched with an amplifier to get any sound from it.
Let's have a brief look at the main features
of Dynaudio Focus 20 XD and Polk TSi100 first before getting into our more

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 Focus 20 XD and TSi100 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 Dynaudio Focus 20 XD's and Polk TSi100's external dimensions. Dynaudio Focus 20 XD has external dimensions of 362.0 x 198.4 x 308.0mm ( 14.25 x 7.8125 x 12.125inch) whereas Polk TSi100 has external dimensions of 279.4 x 177.8 x 259.0mm ( 11.0 x 7.0 x 10.1inch) .

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 20 XD is approximately 611.1cm2 / 94.7inch2 and base area of the Polk TSi100 is approximately 460.5cm2 / 71.4inch2. The Focus 20 XD requires 33% more surface area than the TSi100 which gives it a small disadvantage on placement in tight spaces.
