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 LT and Genelec G Three 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 LT's and Genelec G Three's external dimensions. KEF LSX II LT has external dimensions of 240 × 155 × 180 mm ( 9.5 × 6.1 × 7.1 inch) whereas Genelec G Three has external dimensions of 299 x 189 x 178 mm ( 11.8 x 7.4 x 7) .
KEF LSX II LT is 34mm narrower and 59mm shorter than Genelec G Three but it is also 2mm deeper.
Below you can see the front view size comparison of KEF LSX II LT and Genelec G Three 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 KEF LSX II LT is approximately 279.0cm2 / 43.2inch2 and base area of the Genelec G Three is approximately 336.4cm2 / 52.1inch2. The LSX II LT requires 17% less surface area than the Genelec G Three which gives it a small advantage on placement in tight spaces.
