What size room are the JBL Studio 630 and Klipsch RP-600M 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:

Studio 630 features a 1" High Frequency Compression Tweeter and 1 x 6.25" PolyPlas Woofer . 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
Studio 630 has a frequency range of 45-40k Hz whereas RP-600M has a frequency range of 45-25k Hz.
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
Bookshelf Speakers
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
Studio 630 is a 6 ohms speaker compared to the RP-600M which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Studio 630 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 Studio 630, 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.
Studio 630 can handle a max power of 150 watts RMS from the amp the whereas RP-600M has a max power handling value of 100 watts RMS, 50 watts less than the Studio 630.
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. Studio 630 has a 5-Way post which doesn't feature bi-amping/bi-wiring.
Klipsch RP-600M's Dual binding posts/bi-wire/bi-amp terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Studio 630 and RP-600M 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 JBL Studio 630's and Klipsch RP-600M's external dimensions. JBL Studio 630 has external dimensions of 230 x 280 x 372mm ( 14.6 x 9-1/16inch x 11-1/16inch ) whereas Klipsch RP-600M has external dimensions of 399.0 x 202.0 x 301.0mm ( 15.7 x 7.9 x 11.8inch) .
JBL Studio 630 is 27mm shorter and 21mm less deeper than Klipsch RP-600M but it is also 28mm wider.
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 Studio 630 is approximately 644.0cm2 / 99.8inch2 and base area of the Klipsch RP-600M is approximately 608.0cm2 / 94.2inch2. The Studio 630 requires 6% more surface area than the RP-600M 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 JBL Studio 630 weighs 9.02kg / 19.8lbs and the Klipsch RP-600M weighs 7.30kg / 16.1lbs. This makes the Studio 630 24% heavier than the RP-600M.
Here is a comparison of how Studio 630 and RP-600M's weights compare with the average, max and min weights in Passive Bookshelf class.
