History
What size room are the Polk R600 and Polk R700 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:

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.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that R600 is a 2-way design whereas the R700 is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

R600 features a 1" Pinnacle Ring Radiator Tweeter and 2 x 6.5" Polypropylene Turbine Cone Woofer with a Crossover frequency at 2700Hz. On the other hand, the R700 features a 1" Pinnacle Ring Radiator Tweeter, a 6.5" Midrange and 2 x 8" Polypropylene Woofer with a Crossover frequency at 350Hz and 2700Hz.
Frequency Response
R600 has a frequency range of 43-38k Hz whereas R700 has a frequency range of 38-38k Hz. With a minimum frequency of 38Hz, the R700 can go significantly deeper on the low side and provide stronger bass compared to the R600's min frequency of 43Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
R600 and R700 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R600 sensitivity is rated at 87.5 dB and the R700's is at 88 dB.
Sensitivity
Floor-standing Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
R700 can handle a max power of 300 watts RMS, whereas R600 has a max power handling value of 200 watts RMS, 100 watts less than the R700.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.

Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
R700 features Post posts which make bi-amping or bi-wiring possible. R600 has a Post which doesn't feature bi-amping/bi-wiring.

Physical Specs
The size of a speaker can sometimes be 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 R600's and Polk R700's external dimensions. Polk R600 has external dimensions of 1063.8 x 280.7 x 381.6mm (41.9 x 11 x 15inch) whereas Polk R700 has external dimensions of 1143.8 x 320.7 x 428.3mm (45 x 12.6 x 16.9inch).
Polk R700 is clearly the larger of the two speakers. Its body is 40mm wider, 80mm taller and 46.7mm deeper than Polk R600.
Below you can see the front view size comparison of Polk R600 and Polk R700 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 R600 is approximately 1071.2cm2 / 166.0inch2 and base area of the Polk R700 is approximately 1373.6cm2 / 212.9inch2. The R600 requires 22% less surface area than the R700 which gives it a small advantage 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 Polk R600 weighs 21.50kg / 47.3lbs and the Polk R700 weighs 35.90kg / 79lbs. This makes the R700 67% heavier than the R600.
Here is a comparison of how R600 and R700's weights compare with the average, max and min weights in Passive Floor-standing class.

Siblings in Polk Audio's Reserve series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | B | Polk R700 digs deeper - 38Hz against 43Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (88dB vs 88dB) - both want much the same power. |
| Headroom | B | Polk R700 takes more power (300W vs 200W) - more in hand in a big room. |
| Size | depends | Polk R600 is easier to place; Polk R700 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | B | Polk R700: bi-amping. |
| Price | A | Polk R600 is cheaper - $1,698 against $2,198, about 23% less. |
A Polk R600 B Polk R700
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Polk R700 leads across most of the measured areas for a fairly modest premium, which makes it the easier pick if the budget stretches. Polk R600 is the one to take if it does not. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 43Hz anyway, which makes the cheaper Polk R600 much easier to justify. Match it to your room: we rate Polk R600 the better fit for a mid-size room, and Polk R700 for a very large room.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
