SCM50PSLT SE features a 0.98" Tweeter, a 2.95" Midrange and 1 x 9.21" Woofer with a Crossover frequency at 380Hz & 3.5kHz. On the other hand, the F328Be features a 1" Tweeter, a 5.25" Midrange and 3 x 8.0" Aluminum Woofer.
Frequency Response
SCM50PSLT SE has a frequency range of 70-20k Hz whereas F328Be has a frequency range of 26-40k Hz. With a minimum frequency of 26Hz, the F328Be can go significantly deeper on the low side and provide stronger bass compared to the SCM50PSLT SE's min frequency of 70Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing 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
SCM50PSLT SE and F328Be have the same Impedance of 8 ohms but where they differ is the sensitivity levels. SCM50PSLT SE sensitivity is rated at 85 dB and the F328Be's is at 91 dB. This 6 dB difference makes the Revel PerformaBe F328Be a more sensitive speaker compared to ATC SCM50PSLT SE, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing 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.
F328Be can handle a max power of 300 watts RMS, whereas SCM50PSLT SE has a max power handling value of watts RMS, 300 watts less than the F328Be.
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
F328Be features 5-way posts posts which make bi-amping or bi-wiring possible. SCM50PSLT SE has a XLR which doesn't feature bi-amping/bi-wiring.
Physical Specs
