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. On the other hand, the Heresy IV features a 1" titanium-diaphragm compression horn-loaded Tweeter, a 1.75" Midrange and 1 x 12" Fiber-composite Woofer.
Frequency Response
Silver 500 7G has a frequency range of 27-35k Hz whereas Heresy IV has a frequency range of 48-20k 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 Heresy IV's min frequency of 48Hz.
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
Silver 500 7G and Heresy IV have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Silver 500 7G sensitivity is rated at 90.5 dB and the Heresy IV's is at 99 dB. This 8 dB difference makes the Klipsch Heresy IV 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 Heresy IV has a max power handling value of 100 watts RMS, 150 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.

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
Both Silver 500 7G and Heresy IV features dual binding post speaker terminals for bi-amping or 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 Monitor Audio Silver 500 7G's and Klipsch Heresy IV's external dimensions. 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) whereas Klipsch Heresy IV has external dimensions of 631.0 x 394.0 x 337.0mm (24-13/16 x 15-1/2 x 13-1/4inch).
Klipsch Heresy IV is 454mm shorter and 56mm less deeper than Monitor Audio Silver 500 7G but it is also 71mm wider.
Below you can see the front view size comparison of Monitor Audio Silver 500 7G and Klipsch Heresy IV in scale.

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 Monitor Audio Silver 500 7G is approximately 1269.4cm2 / 196.8inch2 and base area of the Klipsch Heresy IV is approximately 1327.8cm2 / 205.8inch2. The Silver 500 7G requires 4% less surface area than the Heresy IV 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 Monitor Audio Silver 500 7G weighs 22.53kg / 49.6lbs and the Klipsch Heresy IV weighs 20.45kg / 45lbs. This makes the Silver 500 7G 10% heavier than the Heresy IV.

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 | A | Monitor Audio Silver 500 7G digs deeper - 27Hz against 48Hz. |
| Amplifier needs | B | Klipsch Heresy IV is more sensitive (99dB vs 91dB), so it goes louder on the same amplifier. |
| Headroom | A | Monitor Audio Silver 500 7G takes more power (250W vs 100W) - more in hand in a big room. |
| Size | depends | Klipsch Heresy IV is easier to place; Monitor Audio Silver 500 7G is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Monitor Audio Silver 500 7G: bi-amping; Klipsch Heresy IV: bi-amping. Klipsch Heresy IV sits in a wider range (12 models), so a matched surround system is easier later. |
| Price | evenly matched | Much the same money ($3,200 vs $3,198 a pair). |
A Monitor Audio Silver 500 7G B Klipsch Heresy IV
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 48Hz anyway, so judge these on the other rows instead. In a large or open-plan room, Monitor Audio Silver 500 7G has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Klipsch Heresy IV is the easier speaker to get right.
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.
