In this review, we will be comparing Uni-Fi UB5 and Denton 85, two Passive Bookshelf speakers from ELAC and Wharfedale. Let's have a brief look at the main features
of ELAC Uni-Fi UB5 and Wharfedale Denton 85 first before getting into our more
detailed comparison.
What size room are the ELAC Uni-Fi UB5 and Wharfedale Denton 85 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 ELAC Uni-Fi UB5 and Wharfedale Denton 85 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Uni-Fi UB5 is a 3-way design whereas the Denton 85 is a 2-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.

Uni-Fi UB5 features a 1" Soft-dome Tweeter , a 4" Midrange and 1 x 5.25" Aluminum Woofer with a Crossover frequency at 270Hz and 2700Hz. On the other hand, the Denton 85 features a 1" woven textile Soft-Dome Tweeter and 1 x 6.5" Woven Kevlar Woofer with a Crossover frequency at 3100Hz.
Frequency Response
Uni-Fi UB5 has a frequency range of 46-25k Hz whereas Denton 85 has a frequency range of 45-20k Hz. With a minimum frequency of 45Hz, the Denton 85 can go slightly deeper then the Uni-Fi UB5's min frequency of 46Hz.
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

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
Uni-Fi UB5 and Denton 85 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Uni-Fi UB5 sensitivity is rated at 85 dB and the Denton 85's is at 88 dB. This 3 dB difference makes the Wharfedale Denton 85 a more sensitive speaker compared to ELAC Uni-Fi UB5, 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 Uni-Fi UB5 and the Uni-Fi UB5 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.
Uni-Fi UB5 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 UB5.
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 UB5 has a Post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both Uni-Fi UB5 and Denton 85 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 ELAC Uni-Fi UB5's and Wharfedale Denton 85's external dimensions. ELAC Uni-Fi UB5 has external dimensions of 324.0 x 200.0 x 273.0mm ( 12.7 x 7.8 x 10.7inch) whereas Wharfedale Denton 85 has external dimensions of 342.0 x 240.0 x 304.0mm ( 13-7/16v x 9-7/16 x 11-15/16inch) .
Wharfedale Denton 85 is clearly the larger of the two speakers. Its body is 40mm wider, 18mm taller and 31mm deeper than ELAC Uni-Fi UB5.
Below you can see the front view size comparison of ELAC Uni-Fi UB5 and Wharfedale Denton 85 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 ELAC Uni-Fi UB5 is approximately 546.0cm2 / 84.6inch2 and base area of the Wharfedale Denton 85 is approximately 729.6cm2 / 113.1inch2. The Uni-Fi UB5 requires 25% less surface area than the Denton 85 which gives it a small advantage 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 ELAC Uni-Fi UB5 weighs 7.48kg / 16.5lbs and the Wharfedale Denton 85 weighs 9.00kg / 19.8lbs. This makes the Denton 85 20% heavier than the Uni-Fi UB5.
