Platinum 200 3G features a 1" MPD III Tweeter, a 4" Midrange and 1 x 6" RDT III Woofer with a Crossover frequency at 825 Hz - 3000Hz. On the other hand, the 702 S3 features a 1" Tweeter, a 6" Midrange and 3 x 6.5" Aerofoil Woofer.
Frequency Response
Platinum 200 3G has a frequency range of 23-60k Hz whereas 702 S3 has a frequency range of 46-28k Hz. With a minimum frequency of 23Hz, the Platinum 200 3G can go significantly deeper on the low side and provide stronger bass compared to the 702 S3's min frequency of 46Hz.
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
Platinum 200 3G is a 4 ohms speaker compared to the 702 S3 which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Platinum 200 3G can provide this impedance level.
These two speakers also have different sensitivity levels. Platinum 200 3G sensitivity is rated at 88dB and the 702 S3's is rated at 90 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.
Both handle the same maximum of 300 watts RMS, though Platinum 200 3G is rated up to 300 watts and 702 S3 30-300 watts.
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.

Input Type and Bi-Amping / Bi-Wiring
Both Platinum 200 3G and 702 S3 features dual binding post speaker terminals for bi-amping or bi-wiring.
Monitor Audio Platinum 200 3G's Binding post terminals allows Bi-amping or bi-wiring
B&W 702 S3's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Platinum 200 3G and 702 S3 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.

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 Platinum 200 3G's and B&W 702 S3's external dimensions. Monitor Audio Platinum 200 3G has external dimensions of 1041.0 x 368.0 x 455.0mm (41 x 14.5 x 17.8-inch) whereas B&W 702 S3 has external dimensions of 1138.0 x 192.0 x 391.0mm (44.8-inch x 7.6-inch x 15.4-inch).
B&W 702 S3 is 176mm narrower and 64mm less deeper than Monitor Audio Platinum 200 3G but it is also 97mm taller.
Below you can see the front view size comparison of Monitor Audio Platinum 200 3G and B&W 702 S3 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 Platinum 200 3G is approximately 1674.4cm2 / 259.5inch2 and base area of the B&W 702 S3 is approximately 750.7cm2 / 116.4inch2. The Platinum 200 3G requires 123% more surface area than the 702 S3 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 Monitor Audio Platinum 200 3G weighs 35.80kg / 78.8lbs and the B&W 702 S3 weighs 33.46kg / 73.6lbs. This makes the Platinum 200 3G 7% heavier than the 702 S3.
Here is a comparison of how Platinum 200 3G and 702 S3's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - Monitor Audio Platinum 200 3G costs roughly 2x what B&W 702 S3 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 | A | Monitor Audio Platinum 200 3G digs deeper - 23Hz against 46Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (88dB vs 88dB) - both want much the same power. |
| Amplifier match | B | B&W 702 S3 is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | evenly matched | Similar power handling (300W vs 300W). |
| Size | depends | B&W 702 S3 is easier to place; Monitor Audio Platinum 200 3G is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Monitor Audio Platinum 200 3G: bi-amping; B&W 702 S3: bi-amping. B&W 702 S3 sits in a wider range (8 models), so a matched surround system is easier later. |
| Price | B | B&W 702 S3 is cheaper - $6,998 against $13,900, about 50% less; arguably a different class. |
A Monitor Audio Platinum 200 3G B B&W 702 S3
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?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 46Hz anyway, which makes the cheaper B&W 702 S3 much easier to justify. Match it to your room: we rate Monitor Audio Platinum 200 3G the better fit for a very large room; elsewhere the two are rated the same.
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.
