What size room are the ELAC Uni-Fi Ref UBR62 and Monitor Audio Silver 100 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:

Drivers
One of the fundamental differences between these two speakers is that UBR62 is a 3-way design whereas the Silver 100 7G is a 2-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.

UBR62 features a 1" soft dome Tweeter, a 4" Midrange and 1 x 6.5" Aluminum Woofer. On the other hand, the Silver 100 7G features a 1" Hard-Dome Tweeter and 1 x 8" C-CAM RST II Woofer.
Frequency Response
UBR62 has a frequency range of 41-35k Hz whereas Silver 100 7G has a frequency range of 35-35k Hz. With a minimum frequency of 35Hz, the Silver 100 7G can go significantly deeper on the low side and provide stronger bass compared to the UBR62's min frequency of 41Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf 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
UBR62 is a 6 ohms speaker compared to the Silver 100 7G which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. UBR62 sensitivity is rated at 85 dB and the Silver 100 7G's is rated at 87.5 dB. This 3 dB difference makes the Monitor Audio Silver 100 7G a more sensitive speaker compared to ELAC Uni-Fi Ref UBR62, hence will play louder with the same amount of watts.
Sensitivity

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.
UBR62 can handle a max power of 140 watts RMS, whereas Silver 100 7G has a max power handling value of 120 watts RMS, 20 watts less than the UBR62.
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.

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 ELAC Uni-Fi Ref UBR62's and Monitor Audio Silver 100 7G's external dimensions. ELAC Uni-Fi Ref UBR62 has external dimensions of 359.0 x 210.0 x 332.0mm (14-1/8 x 8-1/4 x 13-1/16inch) whereas Monitor Audio Silver 100 7G has external dimensions of 377.0 x 232.0 x 332.0mm (14-13/16 x 9-1/8 x 13-1/16inch).

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 ELAC Uni-Fi Ref UBR62 is approximately 697.2cm2 / 108.1inch2 and base area of the Monitor Audio Silver 100 7G is approximately 770.2cm2 / 119.4inch2. The UBR62 requires 9% less surface area than the Silver 100 7G which gives it a small advantage 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 ELAC Uni-Fi Ref UBR62 weighs 10.70kg / 23.5lbs and the Monitor Audio Silver 100 7G weighs 9.43kg / 20.7lbs. This makes the UBR62 13% heavier than the Silver 100 7G.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass | B | Monitor Audio Silver 100 7G digs deeper - 35Hz against 41Hz. A subwoofer would even that out. |
| Amplifier needs | B | Monitor Audio Silver 100 7G is more sensitive (88dB vs 85dB), so it goes louder on the same amplifier. |
| Amplifier match | B | Monitor Audio Silver 100 7G is the easier load at 8 ohms. |
| Headroom | evenly matched | Similar power handling (140W vs 120W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | ELAC Uni-Fi Ref UBR62: bi-amping; Monitor Audio Silver 100 7G: bi-amping. Monitor Audio Silver 100 7G sits in a wider range (8 models), so a matched surround system is easier later. |
| Price | A | ELAC Uni-Fi Ref UBR62 is cheaper - $1,200 against $1,400, about 14% less. |
A ELAC Uni-Fi Ref UBR62 B Monitor Audio Silver 100 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 100 7G leads across most of the measured areas for a fairly modest premium, which makes it the easier pick if the budget stretches. ELAC Uni-Fi Ref UBR62 is the one to take if it does not. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 41Hz anyway, which makes the cheaper ELAC Uni-Fi Ref UBR62 much easier to justify. If your amplifier is modest, vintage or valve-based, Monitor Audio Silver 100 7G is the safer partner - the other will want more current or more watts to sound its best.
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.
