In this review, we will be comparing ni-Fi 2.0 UC52 and DCR52, two Passive Center Channel speakers by ELAC Let's have a brief look at the main features
of ELAC Uni-Fi 2.0 UC52 and ELAC Debut Ref DCR52 first before getting into our more
detailed comparison.
What size room are the ELAC Uni-Fi 2.0 UC52 and ELAC Debut Ref DCR52 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 2.0 UC52 and ELAC Debut Ref DCR52 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 ni-Fi 2.0 UC52 is a 3-way design whereas the DCR52 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.

ni-Fi 2.0 UC52 features a 1" soft dome Tweeter , a 4" Midrange and 2 x 5.25" dished aluminum Woofer with a Crossover frequency at 200hZ and 2000HZ. On the other hand, the DCR52 features a 1" cloth dome Tweeter and 2 x 5.25" aramid fiber Woofer .
Frequency Response
ni-Fi 2.0 UC52 has a frequency range of 48-35k Hz whereas DCR52 has a frequency range of 55-35k Hz. With a minimum frequency of 48Hz, the ni-Fi 2.0 UC52 can go significantly deeper on the low side and provide stronger bass compared to the DCR52's min frequency of 55Hz.
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 Center Channel class in our database.

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
ni-Fi 2.0 UC52 is a 6 ohms speaker compared to the DCR52 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. ni-Fi 2.0 UC52 sensitivity is rated at 85 dB and the DCR52's is rated at 87 dB. This 2 dB difference makes the ELAC Debut Ref DCR52 a more sensitive speaker compared to ELAC Uni-Fi 2.0 UC52, 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.
ni-Fi 2.0 UC52 can handle a max power of 140 watts RMS from the amp the whereas DCR52 has a max power handling value of 120 watts RMS, 20 watts less than the ni-Fi 2.0 UC52.
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
ni-Fi 2.0 UC52 features 5-Way post type posts and DCR52 has a 5-Way post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both ni-Fi 2.0 UC52 and DCR52 have front firing ports. front ported speakers offers more flexibility in placement in regards to proximity to walls&surfaces compared to rear ported speakers.
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 2.0 UC52's and ELAC Debut Ref DCR52's external dimensions. ELAC Uni-Fi 2.0 UC52 has external dimensions of 186.0 x 545.0 x 294.0mm ( 7-5/16 x 21-7/16 x 11-9/16inch) whereas ELAC Debut Ref DCR52 has external dimensions of 188.0 x 529.0 x 243.0mm ( 7-3/8 x 20-13/16 x 9-9/16inch) .
ELAC Debut Ref DCR52 is 16mm narrower and 51mm less deeper than ELAC Uni-Fi 2.0 UC52 but it is also 2mm 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 ELAC Uni-Fi 2.0 UC52 is approximately 1602.3cm2 / 248.4inch2 and base area of the ELAC Debut Ref DCR52 is approximately 1285.5cm2 / 199.3inch2. The ni-Fi 2.0 UC52 requires 25% more surface area than the DCR52 which gives it a small disadvantage on placement in tight spaces.
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 2.0 UC52 weighs 11.70kg / 25.7lbs and the ELAC Debut Ref DCR52 weighs 10.14kg / 22.3lbs. This makes the ni-Fi 2.0 UC52 15% heavier than the DCR52.
Here is a comparison of how ni-Fi 2.0 UC52 and DCR52's weights compare with the average, max and min weights in Passive Center Channel class.
