Delta features a 1" Titanium dome Horn-Loaded Tweeter, a 6.5" Midrange and 2 x 6.5" Fibreglass Woofer with a Crossover frequency at 280Hz and 2750Hz. 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
Delta has a frequency range of 35-22k 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 Delta's min frequency of 35Hz.
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
Delta and Silver 500 7G have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Delta sensitivity is rated at 92 dB and the Silver 500 7G's is at 90.5 dB. This 1 dB difference makes the Triangle Signature Delta a more sensitive speaker compared to Monitor Audio Silver 500 7G, 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.
Silver 500 7G can handle a max power of 250 watts RMS, whereas Delta has a max power handling value of 120 watts RMS, 130 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.
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
Both Delta and Silver 500 7G features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
Delta has a front firing port whereas Silver 500 7G has a rear firing ports. Triangle Signature Delta's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Monitor Audio Silver 500 7G with its rear-firing port.
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 Triangle Signature Delta's and Monitor Audio Silver 500 7G's external dimensions. Triangle Signature Delta has external dimensions of 1170.0 x 233.0 x 372.0mm (46-1/16 x 9-3/16 x 14-5/8inch) 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).
Triangle Signature Delta is 90mm narrower and 21mm less deeper than Monitor Audio Silver 500 7G but it is also 85mm 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.
Monitor Audio Silver 500 7G needs about 46% more floor or shelf area. Monitor Audio Silver 500 7G is 21mm deeper, so it stands that much further out from the wall. Triangle Signature Delta is 85mm 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 Triangle Signature Delta is approximately 866.8cm2 / 134.4inch2 and base area of the Monitor Audio Silver 500 7G is approximately 1269.4cm2 / 196.8inch2. The Delta requires 32% less surface area than the Silver 500 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 Triangle Signature Delta weighs 33.00kg / 72.6lbs and the Monitor Audio Silver 500 7G weighs 22.53kg / 49.6lbs. This makes the Delta 46% heavier than the Silver 500 7G.
Here is a comparison of how Delta 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 - Triangle Signature Delta costs roughly 1.9x 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 35Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (92dB vs 91dB) - both want much the same power. |
| Headroom | B | Monitor Audio Silver 500 7G takes more power (250W vs 120W) - more in hand in a big room. |
| Size | depends | Triangle Signature Delta is easier to place; Monitor Audio Silver 500 7G is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Triangle Signature Delta: bi-amping; Monitor Audio Silver 500 7G: bi-amping. Monitor Audio Silver 500 7G sits in a wider range (8 models), so a matched surround system is easier later. |
| Price | B | Monitor Audio Silver 500 7G is cheaper - $3,200 against $6,000, about 47% less; arguably a different class. |
A Triangle Signature Delta 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 is the easier recommendation: it leads on most of the measured areas and costs less. Take Triangle Signature Delta if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 35Hz anyway, so judge these on the other rows instead. Think about the whole system, not just the speakers: the roughly $2,800 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
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.
