In this review, we will be comparing Dymension DM40 and Prime Tower, two Passive Floor-standing speakers from Definitive Technology and SVS. Let's have a brief look at the main features
of Definitive Dymension DM40 and SVS Prime Tower first before getting into our more
detailed comparison.
What size room are the Definitive Dymension DM40 and SVS Prime Tower 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 DM40 and SVS Prime Tower 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 DM40 is a 2-way design whereas the Prime Tower 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.

Dymension DM40 features a 1" aluminum oxide 2 x Hard-Dome Tweeter and 4 x 4.5" Polypropelene Woofer . On the other hand, the Prime Tower features a 1" aluminum dome Tweeter , a 4.5" Midrange and 2 x 6.5" Polypropylene Woofer with a Crossover frequency at 350Hz and 2100Hz.
Frequency Response
Dymension DM40 has a frequency range of 55-23 kHz whereas Prime Tower has a frequency range of 30-25k Hz. With a minimum frequency of 30Hz, the Prime Tower can go significantly deeper on the low side and provide stronger bass compared to the Dymension DM40's min frequency of 55Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Floor-standing class in our database.

Definitive Dymension DM40
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 DM40 is a 4 ohms speaker compared to the Prime Tower 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 DM40 can provide this impedance level.
On the other hand, they have the same sensitivity of 87 dBdB.

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 DM40 features 5-Way post type posts and Prime Tower has a 5-Way 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 DM40's and SVS Prime Tower's external dimensions. Definitive Dymension DM40 has external dimensions of 950 x 261 x 255 mm ( 37.4 x 10.3 x 10.0 in) whereas SVS Prime Tower has external dimensions of 931.0 x 204.0 x 297.0mm ( 36-5/8 x 8 x 11-11/16inch) .
SVS Prime Tower is 57mm narrower and 19mm shorter than Definitive Dymension DM40 but it is also 42mm deeper.
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 DM40 is approximately 665.6cm2 / 103.2inch2 and base area of the SVS Prime Tower is approximately 605.9cm2 / 93.9inch2. The Dymension DM40 requires 10% more surface area than the Prime Tower 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 DM40 weighs 17.30kg / 38.1lbs and the SVS Prime Tower weighs 18.23kg / 40.1lbs. This makes the Prime Tower 5% heavier than the Dymension DM40.
Here is a comparison of how Dymension DM40 and Prime Tower's weights compare with the average, max and min weights in Passive Floor-standing class.
