What size room are the Klipsch RP-160M and KEF Q350 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 Q350 features a 1" vented aluminum Dome Tweeter and 1 x 6.5" Aluminum Woofer with a Crossover frequency at 2500Hz.
Frequency Response
RP-160M has a frequency range of 45-25k Hz whereas Q350 has a frequency range of 63-28k 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 Q350's min frequency of 63Hz.
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 Q350 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 Q350's is at 87 dB. This 8 dB difference makes the Klipsch RP-160M a more sensitive speaker compared to KEF Q350, 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.
Q350 can handle a max power of 120 watts RMS, whereas RP-160M has a max power handling value of 100 watts RMS, 20 watts less than the Q350.
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.
Which plays louder on your 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. Q350 has a Post which doesn't feature bi-amping/bi-wiring.

KEF Q350's Post terminals
Cabinet Type and Port Position
Both RP-160M and Q350 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 Q350'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 Q350 has external dimensions of 358.0 x 210.0 x 306.0mm (14.0 x 8.2 x 12.0inch).
Klipsch RP-160M is clearly the larger of the two speakers. Its body is 14mm wider, 66mm taller and 21mm deeper than KEF Q350.
Below you can see the front view size comparison of Klipsch RP-160M and KEF Q350 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 Q350 is approximately 642.6cm2 / 99.6inch2. The RP-160M requires 14% more surface area than the Q350 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 Q350 weighs 7.60kg / 16.7lbs. This makes the RP-160M 19% heavier than the Q350.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass |
A |
Klipsch RP-160M digs deeper - 45Hz against 63Hz. |
| Amplifier needs |
A |
Klipsch RP-160M is more sensitive (95dB vs 87dB), so it goes louder on the same amplifier. |
| Headroom |
evenly matched |
Similar power handling (100W vs 120W). |
| Size |
depends |
KEF Q350 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. |

B KEF Q350
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 63Hz anyway, so judge these on the other rows instead. Match it to your room: we rate Klipsch RP-160M the better fit for near-field listening and a small room, and KEF Q350 for a mid-size room and a 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.
