R-34C features a 1" aluminum Tractrix horn Tweeter and 4 x 3.5" copper spun IMG Woofer. On the other hand, the R-620F features a 1.0" Tweeter and 2 x 6.5" Copper-spun IMG Woofer with a Crossover frequency at 2000Hz.
Frequency Response
R-34C has a frequency range of 82-21k Hz whereas R-620F has a frequency range of 38-21k Hz. With a minimum frequency of 38Hz, the R-620F can go significantly deeper on the low side and provide stronger bass compared to the R-34C's min frequency of 82Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel 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-34C and R-620F have the same Impedance of 8 ohms and their sensitivity is also same at 96 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-34C and R-620F have the same power range of up to 100 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-34C features Post type posts and R-620F has a Post type posts. None of these speakers feature bi-amping/bi-wiring.
