What size room are the ATC SCM150PSL and Monitor Audio Silver 500 7G speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

SCM150PSL features a 0.98" Tweeter, a 2.95" Midrange and 1 x 14.76" Woofer with a Crossover frequency at 380Hz & 3.5kHz. 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
SCM150PSL has a frequency range of 60-17k 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 SCM150PSL's min frequency of 60Hz.
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
SCM150PSL and Silver 500 7G have the same Impedance of 8 ohms but where they differ is the sensitivity levels. SCM150PSL sensitivity is rated at 91 dB and the Silver 500 7G's is at 90.5 dB.
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.
SCM150PSL can handle a max power of 1500 watts RMS, whereas Silver 500 7G has a max power handling value of 250 watts RMS, 1250 watts less than the SCM150PSL.
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.
Monitor Audio Silver 500 7G
Input Type and Bi-Amping / Bi-Wiring
Silver 500 7G features Binding post posts which make bi-amping or bi-wiring possible. SCM150PSL has a XLR 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 SCM150PSL's and Monitor Audio Silver 500 7G's external dimensions. ATC SCM150PSL has external dimensions of 884.0 x 498.0 x 568.0mm () 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 175mm narrower and 175mm less deeper than ATC SCM150PSL but it is also 201mm taller.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
ATC SCM150PSL needs about 123% more floor or shelf area. ATC SCM150PSL is 175mm deeper, so it stands that much further out from the wall. Monitor Audio Silver 500 7G is 201mm taller.
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the ATC SCM150PSL is approximately 2828.6cm2 / 438.4inch2 and base area of the Monitor Audio Silver 500 7G is approximately 1269.4cm2 / 196.8inch2. The SCM150PSL requires 123% more surface area than the Silver 500 7G which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The ATC SCM150PSL weighs 67.20kg / 147.8lbs and the Monitor Audio Silver 500 7G weighs 22.53kg / 49.6lbs. This makes the SCM150PSL 198% heavier than the Silver 500 7G.
Here is a comparison of how SCM150PSL and Silver 500 7G's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - ATC SCM150PSL costs roughly 11.2x what Monitor Audio Silver 500 7G does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | B | Monitor Audio Silver 500 7G digs deeper - 27Hz against 60Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (91dB vs 91dB) - both want much the same power. |
| Headroom | A | ATC SCM150PSL takes more power (1500W vs 250W) - more in hand in a big room. |
| Size | depends | Monitor Audio Silver 500 7G is easier to place; ATC SCM150PSL is bigger, which usually goes with fuller bass. Your room decides. |
| Cabinet | depends | Sealed vs Ported. Sealed is tighter and happier near a wall; ported digs lower but wants space behind it. |
| Expandability | B | Monitor Audio Silver 500 7G: bi-amping. |
| Price | B | Monitor Audio Silver 500 7G is cheaper - $3,200 against $35,999, about 91% less; arguably a different class. |
A ATC SCM150PSL B Monitor Audio Silver 500 7G
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Monitor Audio Silver 500 7G has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 60Hz anyway, so judge these on the other rows instead. Match it to your room: we rate ATC SCM150PSL the better fit for a small room and a mid-size room, and Monitor Audio Silver 500 7G for a large room and a very large room.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
