Drivers
One of the fundamental differences between these two speakers is that SCM20PSLT is a 2-way design whereas the Silver 500 7G is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

SCM20PSLT features a " Tweeter and 1 x " Woofer with a Crossover frequency at 2.2kHz. On the other hand, the Silver 500 7G features a 1" gold dome C-CAM with Uniform Dispersion (UD) Waveguide II Tweeter, a 3" Midrange and 2 x 8" C-CAM RST II Woofer.
Frequency Response
SCM20PSLT has a frequency range of 55-25k Hz whereas Silver 500 7G has a frequency range of 27-35k Hz. With a minimum frequency of 27Hz, the Silver 500 7G can go significantly deeper on the low side and provide stronger bass compared to the SCM20PSLT's min frequency of 55Hz.
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
SCM20PSLT is a ohms speaker compared to the Silver 500 7G which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. SCM20PSLT sensitivity is rated at 85 dB and the Silver 500 7G's is rated at 90.5 dB. This 6 dB difference makes the Monitor Audio Silver 500 7G a more sensitive speaker compared to ATC SCM20PSLT, hence will play louder with the same amount of watts.

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.
Silver 500 7G can handle a max power of 250 watts RMS, whereas SCM20PSLT has a max power handling value of watts RMS, 250 watts less than the Silver 500 7G.
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.
Input Type and Bi-Amping / Bi-Wiring
Silver 500 7G features Binding post posts which make bi-amping or bi-wiring possible. SCM20PSLT has a 1 x Rear Panel Mounted Female XLR, pin 2 hot which doesn't 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 ATC SCM20PSLT's and Monitor Audio Silver 500 7G's external dimensions. ATC SCM20PSLT has external dimensions of () whereas Monitor Audio Silver 500 7G has external dimensions of 1085.0 x 323.0 x 393.0mm (42-11/16 x 12-11/16 x 15-7/16inch).
Monitor Audio Silver 500 7G is clearly the larger of the two speakers. Its body is 323mm wider, 1085mm taller and 393mm deeper than ATC SCM20PSLT.
