DT8LCR features a 1" Hard-Dome Tweeter and 1 x 8" Polypropylene 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
DT8LCR has a frequency range of 27-30kHz whereas R-5800-W II has a frequency range of 40-23kHz. With a minimum frequency of 27Hz, the DT8LCR 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
DT8LCR and R-5800-W II have the same Impedance of 8 ohms but where they differ is the sensitivity levels. DT8LCR sensitivity is rated at 89 dB and the R-5800-W II's is at 94 dB. This 5 dB difference makes the Klipsch R-5800-W II a more sensitive speaker compared to Definitive DT8LCR, 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.
DT8LCR can handle a max power of 100 watts RMS, whereas R-5800-W II has a max power handling value of 50 watts RMS, 50 watts less than the DT8LCR.
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
DT8LCR 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.
