In this review, we will be comparing R-15PM and RP-600M, two Bookshelf speakers by Klipsch The main difference between these two speakers is that the Klipsch R-15PM is a Powered speaker which means that it has a built-in amplifier inside the speaker body so you don't need an external power amp or an integrated amp whereas the Klipsch RP-600M is a Passive speaker so has to be matched with an amplifier to get any sound from it.

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.
Cabinet Type and Port Position
Both R-15PM 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 Klipsch R-15PM's and Klipsch RP-600M's external dimensions. Klipsch R-15PM has external dimensions of 317.5 x 177.8 x 250.8mm ( 12.5 x 7 x 9.875inch) whereas Klipsch RP-600M has external dimensions of 399.0 x 202.0 x 301.0mm ( 15.7 x 7.9 x 11.8inch) .
