Drivers
One of the fundamental differences between these two speakers is that Denton 85 is a 2-way design whereas the Uni-Fi BS U5 Slim is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

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.
Low Frequency
Bookshelf Speakers
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 and Uni-Fi BS U5 Slim have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Denton 85 sensitivity is rated at 88 dB and the Uni-Fi BS U5 Slim's is at 85 dB. This 3 dB difference makes the Wharfedale Denton 85 a more sensitive speaker compared to ELAC Uni-Fi BS U5 Slim, hence will play louder with the same amount of watts.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Denton 85 and the Denton 85 can provide this impedance level.

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 140 watts RMS from the amp the whereas Denton 85 has a max power handling value of 120 watts RMS , 20 watts less than the Uni-Fi BS U5 Slim.
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. Uni-Fi BS U5 Slim has a Post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Denton 85 and Uni-Fi BS U5 Slim 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 ELAC Uni-Fi BS U5 Slim'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 ELAC Uni-Fi BS U5 Slim has external dimensions of 340.0 x 180.0 x 328.0mm ( 13-3/8 x 7-1/16 x 12-7/8inch) .
ELAC Uni-Fi BS U5 Slim is 60mm narrower and 2mm shorter than Wharfedale Denton 85 but it is also 24mm deeper.

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 ELAC Uni-Fi BS U5 Slim is approximately 590.4cm2 / 91.5inch2. The Denton 85 requires 24% more surface area than the Uni-Fi BS U5 Slim which gives it a small disadvantage on placement in tight spaces.
