Reference 7 2023 features a 1" Aluminum oxyd ceramic Tweeter, a 6.85" Midrange and 2 x 6.85" Aluminum ceramic tungsten (Wave-surround) Woofer with a Crossover frequency at 190 / 3200 Hz. On the other hand, the Platinum 300 3G features a 1" MPD III Tweeter, a 4" Midrange and 2 x 8" RDT III Woofer with a Crossover frequency at 650 Hz - 3000 Hz.
Frequency Response
Reference 7 2023 has a frequency range of 23-40k Hz whereas Platinum 300 3G has a frequency range of 17-60k Hz. With a minimum frequency of 17Hz, the Platinum 300 3G can go significantly deeper on the low side and provide stronger bass compared to the Reference 7 2023's min frequency of 23Hz.
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
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.
Platinum 300 3G can handle a max power of 400 watts RMS, whereas Reference 7 2023 has a max power handling value of 320 watts RMS, 80 watts less than the Platinum 300 3G.
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.
Input Type and Bi-Amping / Bi-Wiring
Platinum 300 3G features Binding post posts which make bi-amping or bi-wiring possible. Reference 7 2023 has a Binding post which doesn't feature bi-amping/bi-wiring.
Monitor Audio Platinum 300 3G's Binding post terminals allows 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 Canton Reference 7 2023's and Monitor Audio Platinum 300 3G's external dimensions. Canton Reference 7 2023 has external dimensions of 977.9 x 279.4 x 431.8mm (38.5 x 11 x 17inch) whereas Monitor Audio Platinum 300 3G has external dimensions of 1131.1 x 429.8 x 525 mm (44.5 x 16.9 x 20.6-inch).
Monitor Audio Platinum 300 3G is clearly the larger of the two speakers. Its body is 150.6mm wider, 153.1mm taller and 93.2mm deeper than Canton Reference 7 2023.
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 Platinum 300 3G needs about 87% more floor or shelf area. Monitor Audio Platinum 300 3G is 93mm deeper, so it stands that much further out from the wall. Monitor Audio Platinum 300 3G is 153mm 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 Canton Reference 7 2023 is approximately 1206.4cm2 / 187.0inch2 and base area of the Monitor Audio Platinum 300 3G is approximately 2257.5cm2 / 349.9inch2. The Reference 7 2023 requires 47% less surface area than the Platinum 300 3G 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 Canton Reference 7 2023 weighs 33.11kg / 72.8lbs and the Monitor Audio Platinum 300 3G weighs 53.60kg / 117.9lbs. This makes the Platinum 300 3G 62% heavier than the Reference 7 2023.
Here is a comparison of how Reference 7 2023 and Platinum 300 3G's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - Monitor Audio Platinum 300 3G costs roughly 1.8x what Canton Reference 7 2023 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 Platinum 300 3G digs deeper - 17Hz against 23Hz. A subwoofer would even that out. |
| Headroom | B | Monitor Audio Platinum 300 3G takes more power (400W vs 320W) - more in hand in a big room. |
| Size | depends | Canton Reference 7 2023 is easier to place; Monitor Audio Platinum 300 3G is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | B | Monitor Audio Platinum 300 3G: bi-amping. |
| Price | A | Canton Reference 7 2023 is cheaper - $11,000 against $19,999, about 45% less; arguably a different class. |
A Canton Reference 7 2023 B Monitor Audio Platinum 300 3G
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?
The usual trade-off: Monitor Audio Platinum 300 3G measures better, Canton Reference 7 2023 costs about about 82% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 23Hz anyway, which makes the cheaper Canton Reference 7 2023 much easier to justify. Match it to your room: we rate Canton Reference 7 2023 the better fit for a small room and a mid-size room, and Monitor Audio Platinum 300 3G 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.
