In this review, we will be comparing Denton 85 and LS50, two Passive Bookshelf speakers from Wharfedale and KEF. Let's have a brief look at the main features
of Wharfedale Denton 85 and KEF LS50 first before getting into our more
detailed comparison.
What size room are the Wharfedale Denton 85 and KEF LS50 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 Wharfedale Denton 85 and KEF LS50 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Denton 85 features a 1" woven textile Soft-Dome Tweeter and 1 x 6.5" Woven Kevlar Woofer with a Crossover frequency at 3100Hz. On the other hand, the LS50 features a 1" Aluminum Vented dome Tweeter and 1 x 5.25" Magnesium/aluminum alloy Woofer with a Crossover frequency at 2200Hz.
Frequency Response
Denton 85 has a frequency range of 45-20k Hz whereas LS50 has a frequency range of 79-28k Hz. With a minimum frequency of 45Hz, the Denton 85 can go significantly deeper on the low side and provide stronger bass compared to the LS50's min frequency of 79Hz.
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.

High Frequency
Bookshelf Speakers
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.
Impedance and Sensitivity
Denton 85 is a 4 ohms speaker compared to the LS50 which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Denton 85 can provide this impedance level.
These two speakers also have different sensitivity levels. Denton 85 sensitivity is rated at 88 dB and the LS50's is rated at 85 dB. This 3 dB difference makes the Wharfedale Denton 85 a more sensitive speaker compared to KEF LS50, hence will play louder with the same amount of watts.

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.
Denton 85 can handle a max power of 120 watts RMS from the amp the whereas LS50 has a max power handling value of 100 watts RMS, 20 watts less than the Denton 85.
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
Denton 85 features Post posts which make bi-amping or bi-wiring possible. LS50 has a Post which doesn't feature bi-amping/bi-wiring.

KEF LS50's Post terminals
Cabinet Type and Port Position
Both Denton 85 and LS50 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 Wharfedale Denton 85's and KEF LS50's external dimensions. Wharfedale Denton 85 has external dimensions of 342.0 x 240.0 x 304.0mm ( 13-7/16 x 9-7/16 x 11-15/16inch) whereas KEF LS50 has external dimensions of 302.0 x 200.0 x 278.0mm ( 11.8 x 7.8 x 10.9inch) .
Wharfedale Denton 85 is clearly the larger of the two speakers. Its body is 40mm wider, 40mm taller and 26mm deeper than KEF LS50.
Below you can see the front view size comparison of Wharfedale Denton 85 and KEF LS50 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 Wharfedale Denton 85 is approximately 729.6cm2 / 113.1inch2 and base area of the KEF LS50 is approximately 556.0cm2 / 86.2inch2. The Denton 85 requires 31% more surface area than the LS50 which gives it a small disadvantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 Wharfedale Denton 85 weighs 9.00kg / 19.8lbs and the KEF LS50 weighs 7.20kg / 15.8lbs. This makes the Denton 85 25% heavier than the LS50.
Here is a comparison of how Denton 85 and LS50's weights compare with the average, max and min weights in Passive Bookshelf class.
