In this review, we will be comparing Uni-Fi 2.0 UF52 and RP-280F, two Passive Floor-standing speakers from ELAC and Klipsch. Let's have a brief look at the main features
of ELAC Uni-Fi 2.0 UF52 and Klipsch RP-280F first before getting into our more
detailed comparison.
What size room are the ELAC Uni-Fi 2.0 UF52 and Klipsch RP-280F 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 UF52 and Klipsch RP-280F 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 2.0 UF52 is a 3-way design whereas the RP-280F 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 2.0 UF52 features a 1" soft dome Tweeter , a 4" Midrange and 3 x 5.25" Aluminum Woofer with a Crossover frequency at 200hZ and 2000HZ. On the other hand, the RP-280F features a 1" Tractrix Horn Tweeter and 2 x 8" Cerametallic Woofer .
Frequency Response
Uni-Fi 2.0 UF52 has a frequency range of 42-35k Hz whereas RP-280F has a frequency range of 32-25k Hz. With a minimum frequency of 32Hz, the RP-280F can go significantly deeper on the low side and provide stronger bass compared to the Uni-Fi 2.0 UF52's min frequency of 42Hz.
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 Floor-standing 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
Uni-Fi 2.0 UF52 is a 6 ohms speaker compared to the RP-280F which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Uni-Fi 2.0 UF52 sensitivity is rated at 85 dB and the RP-280F's is rated at 98 dB. This 13 dB difference makes the Klipsch RP-280F a more sensitive speaker compared to ELAC Uni-Fi 2.0 UF52, 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.
Uni-Fi 2.0 UF52 can handle a max power of 150 watts RMS from the amp the whereas Uni-Fi 2.0 UF52 has a max power handling value of 140 watts RMS , 10 watts less than the RP-280F.
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
RP-280F features Binding post posts which make bi-amping or bi-wiring possible. Uni-Fi 2.0 UF52 has a 5-Way post which doesn't feature bi-amping/bi-wiring.
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 UF52's and Klipsch RP-280F's external dimensions. ELAC Uni-Fi 2.0 UF52 has external dimensions of 999.0 x 232.0 x 323.0mm ( 39-5/16 x 9-1/8 x 12-11/16inch) whereas Klipsch RP-280F has external dimensions of 1094.0 x 269.0 x 442.0mm ( 43-1/16 x 10-9/16 x 17-3/8inch) .
Klipsch RP-280F is clearly the larger of the two speakers. Its body is 37mm wider, 95mm taller and 119mm deeper than ELAC Uni-Fi 2.0 UF52.
Below you can see the front view size comparison of ELAC Uni-Fi 2.0 UF52 and Klipsch RP-280F 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 2.0 UF52 is approximately 749.4cm2 / 116.2inch2 and base area of the Klipsch RP-280F is approximately 1189.0cm2 / 184.3inch2. The Uni-Fi 2.0 UF52 requires 37% less surface area than the RP-280F which gives it a small advantage 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 UF52 weighs 19.73kg / 43.4lbs and the Klipsch RP-280F weighs 28.41kg / 62.5lbs. This makes the RP-280F 44% heavier than the Uni-Fi 2.0 UF52.
Here is a comparison of how Uni-Fi 2.0 UF52 and RP-280F's weights compare with the average, max and min weights in Passive Floor-standing class.
