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-5650-W II and R-3800-W II have the same Impedance of 8 ohms and their sensitivity is also same at 93 dB.

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-W II and R-3800-W II have the same power range of up to 50 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.
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-5650-W II features Spring post type posts and R-3800-W II has a Spring post 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-5650-W II's and Klipsch R-3800-W II's external dimensions. Klipsch R-5650-W II has external dimensions of 331.0 x 204.0 x 94.0mm (13.0000-inch x 8.0000-inch x 3.6875-inch) whereas Klipsch R-3800-W II has external dimensions of 374.0 x 232.0 x 99.0mm (14.6875-inch x 9.1250-inch x 3.8750-inch).
Klipsch R-3800-W II is clearly the larger of the two speakers. Its body is 28mm wider, 43mm taller and 5mm deeper than Klipsch R-5650-W II.
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-5650-W II weighs 3.27kg / 7.2lbs and the Klipsch R-3800-W II weighs 3.58kg / 7.9lbs. This makes the R-3800-W II 9% heavier than the R-5650-W II.

Siblings in Klipsch's Reference II series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | B | Klipsch R-3800-W II digs deeper - 46Hz against 52Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (93dB vs 93dB) - both want much the same power. |
| Headroom | evenly matched | Similar power handling (50W vs 50W). |
| Size | depends | Klipsch R-5650-W II is easier to place; Klipsch R-3800-W II is bigger, which usually goes with fuller bass. Your room decides. |
| Price | evenly matched | Much the same money ($858 vs $858 a pair). |
A Klipsch R-5650-W II B Klipsch R-3800-W 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-3800-W II 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 52Hz anyway, so judge these on the other rows instead.
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.
