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
Ultra Bookshelf and RP-600M have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Ultra Bookshelf sensitivity is rated at 87 dB and the RP-600M's is at 96 dB. This 9 dB difference makes the Klipsch RP-600M a more sensitive speaker compared to SVS Ultra Bookshelf, hence will play louder with the same amount of watts.
Sensitivity

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.
Ultra Bookshelf 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 Ultra Bookshelf.
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
Both Ultra Bookshelf and RP-600M features dual binding post speaker terminals for bi-amping or bi-wiring.
SVS Ultra Bookshelf's 5-way post terminals allows Bi-amping or 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 Ultra Bookshelf 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 SVS Ultra Bookshelf's and Klipsch RP-600M's external dimensions. SVS Ultra Bookshelf has external dimensions of 380.0 x 218.0 x 281.0mm ( 14-15/16 x 8-9/16 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) .
SVS Ultra Bookshelf is 19mm shorter and 20mm less deeper than Klipsch RP-600M but it is also 16mm wider.
Below you can see the front view size comparison of SVS Ultra Bookshelf 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 SVS Ultra Bookshelf is approximately 612.6cm2 / 95.0inch2 and base area of the Klipsch RP-600M is approximately 608.0cm2 / 94.2inch2. The Ultra Bookshelf requires 1% more surface area than the RP-600M 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 SVS Ultra Bookshelf weighs 8.64kg / 19lbs and the Klipsch RP-600M weighs 7.30kg / 16.1lbs. This makes the Ultra Bookshelf 18% heavier than the RP-600M.
Here is a comparison of how Ultra Bookshelf and RP-600M's weights compare with the average, max and min weights in Passive Bookshelf class.
