In this review, we will be comparing RP-600M and Uni-Fi UB5, two Passive Bookshelf speakers from Klipsch and ELAC. Let's have a brief look at the main features
of Klipsch RP-600M and ELAC Uni-Fi UB5 first before getting into our more
detailed comparison.
What size room are the Klipsch RP-600M and ELAC Uni-Fi UB5 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 Klipsch RP-600M and ELAC Uni-Fi UB5 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 RP-600M 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.

RP-600M features a 1" Tractrix Horn Tweeter and 1 x 6.5" Cerametallic Woofer with a Crossover frequency at 1500Hz. 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
RP-600M has a frequency range of 45-25k Hz whereas Uni-Fi UB5 has a frequency range of 46-25k Hz. With a minimum frequency of 45Hz, the RP-600M 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.

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
RP-600M is a 8 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. RP-600M sensitivity is rated at 96 dB and the Uni-Fi UB5's is rated at 85 dB. This 11 dB difference makes the Klipsch RP-600M 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.
RP-600M can handle a max power of 140 watts RMS from the amp the whereas RP-600M has a max power handling value of 100 watts RMS , 40 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
RP-600M features Dual binding posts/bi-wire/bi-amp 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 RP-600M and Uni-Fi UB5 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 Klipsch RP-600M's and ELAC Uni-Fi UB5's external dimensions. Klipsch RP-600M has external dimensions of 399.0 x 202.0 x 301.0mm ( 15.7 x 7.9 x 11.8inch) 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) .
Klipsch RP-600M is clearly the larger of the two speakers. Its body is 2mm wider, 75mm taller and 28mm deeper than ELAC Uni-Fi UB5.
Below you can see the front view size comparison of Klipsch RP-600M 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 Klipsch RP-600M is approximately 608.0cm2 / 94.2inch2 and base area of the ELAC Uni-Fi UB5 is approximately 546.0cm2 / 84.6inch2. The RP-600M requires 11% more surface area than the Uni-Fi UB5 which gives it a small disadvantage 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 Klipsch RP-600M weighs 7.30kg / 16.1lbs and the ELAC Uni-Fi UB5 weighs 7.48kg / 16.5lbs. This makes the Uni-Fi UB5 2% heavier than the RP-600M.
Here is a comparison of how RP-600M and Uni-Fi UB5's weights compare with the average, max and min weights in Passive Bookshelf class.
