R-1650-W features a 1" Soft-Dome Tweeter and 1 x 6.5" Poly Woofer. On the other hand, the R-5650-S II features a 1" Horn-loaded dome Tweeter and 1 x 6.5" Cerametallic Woofer with a Crossover frequency at 3400 Hz.
Frequency Response
R-1650-W has a frequency range of 53-20kHz whereas R-5650-S II has a frequency range of 60-23kHz. With a minimum frequency of 53Hz, the R-1650-W can go significantly deeper on the low side and provide stronger bass compared to the R-5650-S II's min frequency of 60Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the In-wall class in our database.
Low Frequency
In-wall 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
R-1650-W and R-5650-S II have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R-1650-W sensitivity is rated at 88 dB and the R-5650-S II's is at 92 dB. This 4 dB difference makes the Klipsch R-5650-S II a more sensitive speaker compared to Klipsch R-1650-W, hence will play louder with the same amount of watts.
Sensitivity
In-wall 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.
R-5650-S II can handle a max power of 50 watts RMS, whereas R-1650-W has a max power handling value of 35 watts RMS, 15 watts less than the R-5650-S II.
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
R-1650-W features Spring Posts type posts and R-5650-S II has a Spring Posts type posts. None of these speakers 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 Klipsch R-1650-W's and Klipsch R-5650-S II's external dimensions. Klipsch R-1650-W has external dimensions of 331.0 x 204.0 x 77.0mm (13.0000-inch x 8.0000-inch x 3.0000-inch) whereas Klipsch R-5650-S II has external dimensions of 331.0 x 204.0 x 94.0mm (13.0000-inch x 8.0000-inch x 3.6875-inch).
Klipsch R-1650-W has the same height and width with Klipsch R-5650-S II. On the other hand, with a thickness of 77.0mm, it is 17mm less deeper.
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 R-1650-W weighs 2.95kg / 6.5lbs and the Klipsch R-5650-S II weighs 3.27kg / 7.2lbs. This makes the R-5650-S II 11% heavier than the R-1650-W.
Here is a comparison of how R-1650-W and R-5650-S II's weights compare with the average, max and min weights in Passive In-wall class.

Both are Klipsch, from different ranges - so the house sound is shared and the differences are mostly in scale, engineering and price.
| Area | Better | Why |
|---|
| Bass | A | Klipsch R-1650-W digs deeper - 53Hz against 60Hz. A subwoofer would even that out. |
| Amplifier needs | B | Klipsch R-5650-S II is more sensitive (92dB vs 88dB), so it goes louder on the same amplifier. |
| Headroom | B | Klipsch R-5650-S II takes more power (50W vs 35W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Price | A | Klipsch R-1650-W is cheaper - $318 against $458, about 31% less. |
A Klipsch R-1650-W B Klipsch R-5650-S II
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?
Klipsch R-5650-S II is ahead, but only on 1 of the measured areas, and it costs about 44% more. That is a lot of money for a narrow margin on paper - Klipsch R-1650-W looks like the sensible buy unless something else about the Klipsch R-5650-S II appeals to you. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 60Hz anyway, so judge these on the other rows instead. If your amplifier is modest, vintage or valve-based, Klipsch R-5650-S II is the safer partner - the other will want more current or more watts to sound its best.
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.
