In this review, we will be comparing Dymension DM20 and Silver C250 7G, two Passive Center Channel speakers from Definitive Technology and Monitor Audio . Let's have a brief look at the main features
of Definitive Dymension DM20 and Monitor Audio Silver C250 7G first before getting into our more
detailed comparison.
What size room are the Definitive Dymension DM20 and Monitor Audio Silver C250 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:
In the following sections, we will get into more detail in order to better understand how the Definitive Dymension DM20 and Monitor Audio Silver C250 7G compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Dymension DM20 is a 2-way design whereas the Silver C250 7G is a 3-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.

None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Dymension DM20 is a 4 ohms speaker compared to the Silver C250 7G 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 Dymension DM20 can provide this impedance level.
These two speakers also have different sensitivity levels. Dymension DM20 sensitivity is rated at 89 dB and the Silver C250 7G's is rated at 88.5 dB.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Dymension DM20 features Binding post type posts and Silver C250 7G has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
Physical Specs
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Definitive Dymension DM20's and Monitor Audio Silver C250 7G's external dimensions. Definitive Dymension DM20 has external dimensions of 134 x 775 x 166 mm ( 5.3 x 30.5 x 6.5 in) whereas Monitor Audio Silver C250 7G has external dimensions of 205.0 x 482.0 x 274.0mm ( 8-1/16 x 18-15/16 x 10-3/4inch) .
Definitive Dymension DM20 is 71mm shorter and 108mm less deeper than Monitor Audio Silver C250 7G but it is also 293mm wider.
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 Definitive Dymension DM20 is approximately 1286.5cm2 / 199.4inch2 and base area of the Monitor Audio Silver C250 7G is approximately 1320.7cm2 / 204.7inch2. The Dymension DM20 requires 3% less surface area than the Silver C250 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 Definitive Dymension DM20 weighs 10.00kg / 22lbs and the Monitor Audio Silver C250 7G weighs 10.63kg / 23.4lbs. This makes the Silver C250 7G 6% heavier than the Dymension DM20.
Here is a comparison of how Dymension DM20 and Silver C250 7G's weights compare with the average, max and min weights in Passive Center Channel class.
