What size room are the Klipsch RP-160M and KEF Q150 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:

RP-160M features a 1" Tractrix Horn Tweeter and 1 x 6.5" Cerametallic Woofer with a Crossover frequency at 1500Hz. On the other hand, the Q150 features a 1" vented aluminum Dome Tweeter and 1 x 5.25" Aluminum Woofer with a Crossover frequency at 2500Hz.
Frequency Response
RP-160M has a frequency range of 45-25k Hz whereas Q150 has a frequency range of 51-28k Hz. With a minimum frequency of 45Hz, the RP-160M can go significantly deeper on the low side and provide stronger bass compared to the Q150's min frequency of 51Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf 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
RP-160M and Q150 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-160M sensitivity is rated at 95 dB and the Q150's is at 86 dB. This 9 dB difference makes the Klipsch RP-160M a more sensitive speaker compared to KEF Q150, hence will play louder with the same amount of watts.
Sensitivity
Bookshelf 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.
Both handle the same maximum of 100 watts RMS, though RP-160M is rated up to 100 watts and Q150 10-100 watts.
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
RP-160M features Dual binding posts posts which make bi-amping or bi-wiring possible. Q150 has a Post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both RP-160M and Q150 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
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 Klipsch RP-160M's and KEF Q150's external dimensions. Klipsch RP-160M has external dimensions of 424.0 x 224.0 x 327.0mm (16.6 x 8.8 x 12.8inch) whereas KEF Q150 has external dimensions of 303.0 x 180.0 x 278.0mm (11.9 x 7.0 x 10.9inch).
Klipsch RP-160M is clearly the larger of the two speakers. Its body is 44mm wider, 121mm taller and 49mm deeper than KEF Q150.
Below you can see the front view size comparison of Klipsch RP-160M and KEF Q150 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 Klipsch RP-160M is approximately 732.5cm2 / 113.5inch2 and base area of the KEF Q150 is approximately 500.4cm2 / 77.6inch2. The RP-160M requires 46% more surface area than the Q150 which gives it a small disadvantage on placement in tight spaces.
Here is 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 Klipsch RP-160M weighs 9.03kg / 19.9lbs and the KEF Q150 weighs 5.60kg / 12.3lbs. This makes the RP-160M 61% heavier than the Q150.
Here is a comparison of how RP-160M and Q150's weights compare with the average, max and min weights in Passive Bookshelf class.

A generation apart: KEF Q150 is the newer design, against a 2015 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass |
A |
Klipsch RP-160M digs deeper - 45Hz against 51Hz. A subwoofer would even that out. |
| Amplifier needs |
A |
Klipsch RP-160M is more sensitive (95dB vs 86dB), so it goes louder on the same amplifier. |
| Headroom |
evenly matched |
Similar power handling (100W vs 100W). |
| Size |
depends |
KEF Q150 is easier to place; Klipsch RP-160M is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability |
A |
Klipsch RP-160M: bi-amping. Klipsch RP-160M sits in a wider range (17 models), so a matched surround system is easier later. |
A Klipsch RP-160M
B KEF Q150
depends neither is better in the abstract - it turns on your room, placement 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?
Klipsch RP-160M has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 51Hz anyway, so judge these on the other rows instead. In a large or open-plan room, Klipsch RP-160M has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, KEF Q150 is the easier speaker to get right.
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.
