DT6.5LCR features a 1" Hard-Dome Tweeter and 1 x 6.5" Polypropylene Woofer. On the other hand, the Stage 280W features a 1" Horn-Loaded Tweeter and 1 x 8" Polycellulose Woofer.
Frequency Response
DT6.5LCR has a frequency range of 28-30kHz whereas Stage 280W has a frequency range of 42-25kHz. With a minimum frequency of 28Hz, the DT6.5LCR can go significantly deeper on the low side and provide stronger bass compared to the Stage 280W's min frequency of 42Hz.
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
DT6.5LCR and Stage 280W have the same Impedance of 8 ohms but where they differ is the sensitivity levels. DT6.5LCR sensitivity is rated at 89 dB and the Stage 280W's is at 90 dB. This 1 dB difference makes the JBL Stage 280W a more sensitive speaker compared to Definitive DT6.5LCR, 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.
Stage 280W can handle a max power of 120 watts RMS, whereas DT6.5LCR has a max power handling value of 100 watts RMS, 20 watts less than the Stage 280W.
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
DT6.5LCR features Spring clip type posts and Stage 280W has a Spring clip 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 DT6.5LCR's and JBL Stage 280W's external dimensions. Definitive DT6.5LCR has external dimensions of 324.0 x 185.0 x 86.0mm (12.7500-inch x 7.2500-inch x 3.3750-inch) whereas JBL Stage 280W has external dimensions of 374.0 x 239.0 x 99.0mm (14.6875-inch x 9.3750-inch x 3.8750-inch).
