Drivers
One of the fundamental differences between these two speakers is that DBR62 is a 2-way design whereas the Uni-Fi UB5 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.

DBR62 features a 1" Soft-Dome Tweeter and 1 x 6.5" Aramid fiber Woofer . On the other hand, the 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.
Frequency Response
DBR62 has a frequency range of 44-35k Hz whereas Uni-Fi UB5 has a frequency range of 46-25k Hz. With a minimum frequency of 44Hz, the DBR62 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.

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
DBR62 is a 6 ohms speaker compared to the Uni-Fi UB5 which has a nominal impedance of 4 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 Uni-Fi UB5 can provide this impedance level.
These two speakers also have different sensitivity levels. DBR62 sensitivity is rated at 86 dB and the Uni-Fi UB5's is rated at 85 dB. This 1 dB difference makes the ELAC Debut Ref DBR62 a more sensitive speaker compared to ELAC Uni-Fi UB5, 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.
DBR62 can handle a max power of 140 watts RMS from the amp the whereas DBR62 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
DBR62 features Post type posts and Uni-Fi UB5 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
DBR62 has a front firing port whereas Uni-Fi UB5 has a rear firing ports. ELAC Debut Ref DBR62's front-firing port gives more flexibility in placement in regards to proximity to walls compared to ELAC Uni-Fi UB5 with its rear-firing port.
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 Debut Ref DBR62's and ELAC Uni-Fi UB5's external dimensions. ELAC Debut Ref DBR62 has external dimensions of 362.0 x 210.0 x 277.0mm ( 14-1/4 x 8-1/4 x 10-7/8inch) whereas ELAC Uni-Fi UB5 has external dimensions of 324.0 x 200.0 x 273.0mm ( 12.7 x 7.8 x 10.7inch) .
ELAC Debut Ref DBR62 is clearly the larger of the two speakers. Its body is 10mm wider, 38mm taller and 4mm deeper than ELAC Uni-Fi UB5.
Below you can see the front view size comparison of ELAC Debut Ref DBR62 and ELAC Uni-Fi UB5 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 Debut Ref DBR62 is approximately 581.7cm2 / 90.2inch2 and base area of the ELAC Uni-Fi UB5 is approximately 546.0cm2 / 84.6inch2. The DBR62 requires 7% more surface area than the Uni-Fi UB5 which gives it a small disadvantage on placement in tight spaces.
