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.
Cabinet Type and Port Position
Both ORA and LSX II 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 Kanto ORA's and KEF LSX II's external dimensions. Kanto ORA has external dimensions of 177.0 x 101.0 x 189.0mm ( 6.94inch x 3.94inch x 7.5inch ) whereas KEF LSX II has external dimensions of 240 × 155 × 180 mm ( 9.5 × 6.1 × 7.1 inch) .
Kanto ORA is 54mm narrower and 63mm shorter than KEF LSX II but it is also 9mm deeper.
Below you can see the front view size comparison of Kanto ORA and KEF LSX II 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 Kanto ORA is approximately 190.9cm2 / 29.6inch2 and base area of the KEF LSX II is approximately 279.0cm2 / 43.2inch2. The ORA requires 32% less surface area than the LSX II which gives it a small advantage on placement in tight spaces.
