L52 Classic features a 0.75" Titanium Dome Tweeter and 1 x 5.25" Pulp Woofer with a Crossover frequency at 2800Hz. On the other hand, the RP-600M features a 1" Tractrix Horn Tweeter and 1 x 6.5" Cerametallic Woofer with a Crossover frequency at 1500Hz.
Frequency Response
L52 Classic has a frequency range of 47-24k Hz whereas RP-600M has a frequency range of 45-25k Hz. With a minimum frequency of 45Hz, the RP-600M can go slightly deeper then the L52 Classic's min frequency of 47Hz.
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.

High Frequency

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
L52 Classic is a 4 ohms speaker compared to the RP-600M which has a nominal impedance of 8 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 L52 Classic can provide this impedance level.
These two speakers also have different sensitivity levels. L52 Classic sensitivity is rated at 85 dB and the RP-600M's is rated at 96 dB. This 11 dB difference makes the Klipsch RP-600M a more sensitive speaker compared to JBL L52 Classic, 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.
L52 Classic can handle a max power of 100 watts RMS from the amp the whereas L52 Classic has a max power handling value of 75 watts RMS , 25 watts less than the RP-600M.
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. L52 Classic has a Five-way gold-plated binding posts which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
L52 Classic has a front firing port whereas RP-600M has a rear firing ports. JBL L52 Classic's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Klipsch RP-600M 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 JBL L52 Classic's and Klipsch RP-600M's external dimensions. JBL L52 Classic has external dimensions of 332.0 x 199.0 x 221.0mm ( 13-1/16 x 7-13/16 x 8-11/16inch) whereas Klipsch RP-600M has external dimensions of 399.0 x 202.0 x 301.0mm ( 15.7 x 7.9 x 11.8inch) .
Klipsch RP-600M is clearly the larger of the two speakers. Its body is 3mm wider, 67mm taller and 80mm deeper than JBL L52 Classic.
Below you can see the front view size comparison of JBL L52 Classic and Klipsch RP-600M 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 JBL L52 Classic is approximately 439.8cm2 / 68.2inch2 and base area of the Klipsch RP-600M is approximately 608.0cm2 / 94.2inch2. The L52 Classic requires 28% less surface area than the RP-600M which gives it a small advantage 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 JBL L52 Classic weighs 5.00kg / 11lbs and the Klipsch RP-600M weighs 7.30kg / 16.1lbs. This makes the RP-600M 46% heavier than the L52 Classic.
Here is a comparison of how L52 Classic and RP-600M's weights compare with the average, max and min weights in Passive Bookshelf class.
