What size room are the Polk TSi100 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:

Listening Environment* Polk TSi100 Klipsch RP-600M
Near-field Average Average
Small Room Good Good
Mid-size Room Average Average
Large Room Poor Poor
Very Large Room Bad Bad

(* Approximate Room sizes: Small < 100sq. ft / 9 m2, Mid-size: 100-220 sq. ft / 9-20 m2, Large 220-400 sq. ft / 20-36 m2, Very Large: > 400 sq. ft / 36 m2. Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual listening experience changes depending on floor height, room shape, surface materials, listening position, speaker locations, etc.)

In the following sections, we will get into more detail in order to better understand how the Polk TSi100 and Klipsch RP-600M compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

TSi100 features a 1" Dome Tweeter and 1 x 5.25" Organic Fiber Woofer with a Crossover frequency at 2500Hz. 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

TSi100 has a frequency range of 61-24k Hz whereas RP-600M has a frequency range of 45-25k Hz. With a minimum frequency of 45Hz, the RP-600M can go significantly deeper on the low side and provide stronger bass compared to the TSi100's min frequency of 61Hz.

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

TSi100 and RP-600M have the same Impedance of 8 ohms but where they differ is the sensitivity levels. TSi100 sensitivity is rated at 89 dB and the RP-600M's is at 96 dB. This 7 dB difference makes the Klipsch RP-600M a more sensitive speaker compared to Polk TSi100, 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.

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. TSi100 has a Pair of 5-way Binding Posts - Gold-Plated which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position

Both TSi100 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 Polk TSi100's and Klipsch RP-600M's external dimensions. Polk TSi100 has external dimensions of 279.4 x 177.8 x 259.0mm ( 11.0 x 7.0 x 10.1inch) 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 24.2mm wider, 119.6mm taller and 42mm deeper than Polk TSi100.

Below you can see the front view size comparison of Polk TSi100 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 Polk TSi100 is approximately 460.5cm2 / 71.4inch2 and base area of the Klipsch RP-600M is approximately 608.0cm2 / 94.2inch2. The TSi100 requires 24% 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 Polk TSi100 weighs 4.53kg / 10lbs and the Klipsch RP-600M weighs 7.30kg / 16.1lbs. This makes the RP-600M 61% heavier than the TSi100.

Here is a comparison of how TSi100 and RP-600M's weights compare with the average, max and min weights in Passive Bookshelf class.
