DI 6.5S features a 1" Hard-Dome Tweeter and 1 x 6.5" Polymer Woofer. On the other hand, the R-5800-W II features a 1" Horn-loaded dome Tweeter and 1 x 8" Cerametallic Woofer with a Crossover frequency at 2600 Hz.
Frequency Response
DI 6.5S has a frequency range of 26-30kHz whereas R-5800-W II has a frequency range of 40-23kHz. With a minimum frequency of 26Hz, the DI 6.5S can go significantly deeper on the low side and provide stronger bass compared to the R-5800-W II's min frequency of 40Hz.
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
DI 6.5S and R-5800-W II have the same Impedance of 8 ohms but where they differ is the sensitivity levels. DI 6.5S sensitivity is rated at 90 dB and the R-5800-W II's is at 94 dB. This 4 dB difference makes the Klipsch R-5800-W II a more sensitive speaker compared to Definitive DI 6.5S, 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.
DI 6.5S can handle a max power of 200 watts RMS, whereas R-5800-W II has a max power handling value of 50 watts RMS, 150 watts less than the DI 6.5S.
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
DI 6.5S features Spring post type posts and R-5800-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 Definitive DI 6.5S's and Klipsch R-5800-W II's external dimensions. Definitive DI 6.5S has external dimensions of 185.0 x 185.0 x 104.0mm (7.2500-inch x 7.2500-inch x 4.0625-inch) whereas Klipsch R-5800-W II has external dimensions of 374.0 x 232.0 x 101.0mm (14.6875-inch x 9.1250-inch x 3.9375-inch).
Definitive DI 6.5S is 47mm narrower and 189mm shorter than Klipsch R-5800-W II but it is also 3mm deeper.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Klipsch R-5800-W II needs about 22% more floor or shelf area. Klipsch R-5800-W II is 189mm taller.
