DBR62 features a 1" Soft-Dome Tweeter and 1 x 6.5" Aramid fiber Woofer . On the other hand, the R-51M features a 1" Tractrix Horn Tweeter and 1 x 5.25" Copper-spun IMG Woofer with a Crossover frequency at 1660Hz.
Frequency Response
DBR62 has a frequency range of 44-35k Hz whereas R-51M has a frequency range of 62-21k Hz. With a minimum frequency of 44Hz, the DBR62 can go significantly deeper on the low side and provide stronger bass compared to the R-51M's min frequency of 62Hz.
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
DBR62 is a 6 ohms speaker compared to the R-51M which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. DBR62 sensitivity is rated at 86 dB and the R-51M's is rated at 93 dB. This 7 dB difference makes the Klipsch R-51M a more sensitive speaker compared to ELAC Debut Ref DBR62, 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 120 watts RMS from the amp the whereas R-51M has a max power handling value of 85 watts RMS, 35 watts less than the DBR62.
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 Single Gold Plated Binding Posts - 5-way type posts and R-51M has a Single Gold Plated Binding Posts - 5-way type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
DBR62 has a front firing port whereas R-51M 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 Klipsch R-51M 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 Klipsch R-51M'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 Klipsch R-51M has external dimensions of 338.0 x 178.0 x 215.0mm ( 13.3 x 7.0 x 8.4inch) .
ELAC Debut Ref DBR62 is clearly the larger of the two speakers. Its body is 32mm wider, 24mm taller and 62mm deeper than Klipsch R-51M.
Below you can see the front view size comparison of ELAC Debut Ref DBR62 and Klipsch R-51M 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 Klipsch R-51M is approximately 382.7cm2 / 59.3inch2. The DBR62 requires 52% more surface area than the R-51M 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 ELAC Debut Ref DBR62 weighs 8.23kg / 18.1lbs and the Klipsch R-51M weighs 5.00kg / 11lbs. This makes the DBR62 65% heavier than the R-51M.
