Let's have a brief look at the main features
of KEF LS50 and KEF LS50C Meta first before getting into our more
detailed comparison.
LS50 and LS50C Meta are members of KEF's LS series of speakers. Below you can find the loudspeakers from this series.
What size room are the KEF LS50 and KEF LS50C Meta speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the KEF LS50 and KEF LS50C Meta compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
LS50 features Binding post type posts and LS50C Meta has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both LS50 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 LS50's and KEF LS50C Meta's external dimensions. KEF LS50 has external dimensions of 302.0 x 200.0 x 278.0mm ( 11.8 x 7.8 x 10.9inch) 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 LS50 is 1mm narrower and 3mm less deeper than KEF LS50C Meta but it is also 1mm 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 KEF LS50 is approximately 556.0cm2 / 86.2inch2 and base area of the KEF LS50C Meta is approximately 564.8cm2 / 87.5inch2. The LS50 requires 2% less surface area than the LS50C Meta which gives it a small advantage on placement in tight spaces.
