Dymension DM10 features a 1" aluminum oxide Hard-Dome Tweeter and 2 x 5.25" Polypropelene Woofer. On the other hand, the ProCenter 2000 features a 1" pure aluminum dome Tweeter and 2 x 5.25" BDSS Woofer.
Frequency Response
Dymension DM10 has a frequency range of 81-23 kHz whereas ProCenter 2000 has a frequency range of 42-30k Hz. With a minimum frequency of 42Hz, the ProCenter 2000 can go significantly deeper on the low side and provide stronger bass compared to the Dymension DM10's min frequency of 81Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel 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
Dymension DM10 is a 4 ohms speaker compared to the ProCenter 2000 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 DM10 can provide this impedance level.
These two speakers also have different sensitivity levels. Dymension DM10 sensitivity is rated at 90 dB and the ProCenter 2000's is rated at 91 dB. This 1 dB difference makes the Definitive ProCenter 2000 a more sensitive speaker compared to Definitive Dymension DM10, hence will play louder with the same amount of watts.
Sensitivity
Center Channel 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.
ProCenter 2000 can handle a max power of 250 watts RMS, whereas Dymension DM10 has a max power handling value of 200 watts RMS, 50 watts less than the ProCenter 2000.
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
Dymension DM10 features 5-Way post type posts and ProCenter 2000 has a 5-Way post type posts. None of these speakers feature bi-amping/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 Definitive Dymension DM10's and Definitive ProCenter 2000's external dimensions. Definitive Dymension DM10 has external dimensions of 186 x 496 x 311 mm (7.3 x 19.5 x 12.2 in) whereas Definitive ProCenter 2000 has external dimensions of 169.0 x 432.0 x 164.0mm (6-5/8 x 17 x 6-7/16inch).
Definitive Dymension DM10 is clearly the larger of the two speakers. Its body is 64mm wider, 17mm taller and 147mm deeper than Definitive ProCenter 2000.
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 DM10 is approximately 1542.6cm2 / 239.1inch2 and base area of the Definitive ProCenter 2000 is approximately 708.5cm2 / 109.8inch2. The Dymension DM10 requires 118% more surface area than the ProCenter 2000 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 Definitive Dymension DM10 weighs 13.20kg / 29lbs and the Definitive ProCenter 2000 weighs 4.55kg / 10lbs. This makes the Dymension DM10 190% heavier than the ProCenter 2000.
Here is a comparison of how Dymension DM10 and ProCenter 2000's weights compare with the average, max and min weights in Passive Center Channel class.

These sit in different price classes - Definitive Dymension DM10 costs roughly 1.8x what Definitive ProCenter 2000 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 | Definitive ProCenter 2000 digs deeper - 42Hz against 81Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (90dB vs 91dB) - both want much the same power. |
| Amplifier match | B | Definitive ProCenter 2000 is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | B | Definitive ProCenter 2000 takes more power (250W vs 200W) - more in hand in a big room. |
| Size | depends | Definitive ProCenter 2000 is easier to place; Definitive Dymension DM10 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Neither adds bi-amping, a sub output or height drivers. Definitive Dymension DM10 sits in a wider range (8 models), so a matched surround system is easier later. |
| Price | B | Definitive ProCenter 2000 is cheaper - $379 against $699, about 46% less; arguably a different class. |
A Definitive Dymension DM10 B Definitive ProCenter 2000
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?
Definitive ProCenter 2000 is the easier recommendation: it leads on most of the measured areas and costs less. Take Definitive Dymension DM10 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 81Hz anyway, so judge these on the other rows instead. Match it to your room: we rate Definitive Dymension DM10 the better fit for a small room, and Definitive ProCenter 2000 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.
