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 Active 200 and LS50 Wireless 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 Q Acoustics Q Active 200's and KEF LS50 Wireless II's external dimensions. Q Acoustics Q Active 200 has external dimensions of 285.0 x 172.0 x 291.0mm ( 11-3/16 x 6-3/4 x 11-7/16inch) whereas KEF LS50 Wireless II has external dimensions of 277.8 x 200.0 x 322.3mm ( 10.9375 x 7.875 x 12.6875inch) .
Q Acoustics Q Active 200 is 28mm narrower and 31.3mm less deeper than KEF LS50 Wireless II but it is also 7.2mm taller.
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 Q Acoustics Q Active 200 is approximately 500.5cm2 / 77.6inch2 and base area of the KEF LS50 Wireless II is approximately 644.6cm2 / 99.9inch2. The Active 200 requires 22% less surface area than the LS50 Wireless II which gives it a small advantage on placement in tight spaces.
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 Q Acoustics Q Active 200 weighs 7.50kg / 16.5lbs and the KEF LS50 Wireless II weighs 10.00kg / 22lbs. This makes the LS50 Wireless II 33% heavier than the Active 200.
