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 LSX II and LS50C Meta 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 KEF LSX II's and KEF LS50C Meta's external dimensions. KEF LSX II has external dimensions of 240 × 155 × 180 mm ( 9.5 × 6.1 × 7.1 inch) whereas KEF LS50C Meta has external dimensions of 301.0 x 201.0 x 281.0mm ( 11-13/16 x 7-7/8 x 11-1/16inch) .
KEF LS50C Meta is clearly the larger of the two speakers. Its body is 46mm wider, 61mm taller and 101mm deeper than KEF LSX II.
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 LS50C Meta is approximately 564.8cm2 / 87.5inch2. The LSX II requires 51% less surface area than the LS50C Meta which gives it a small advantage on placement in tight spaces.
