Drivers
One of the fundamental differences between these two speakers is that Dymension DM10 is a 2-way design whereas the Dymension DM70 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 DM10 and Dymension DM70 have the same Impedance of 4 ohms and their sensitivity is also same at 90 dB.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Dymension DM10 and the Dymension DM10 can provide this impedance level.

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.
Dymension DM10 can handle a max power of 300 watts RMS from the amp the whereas Dymension DM10 has a max power handling value of 200 watts RMS , 100 watts less than the Dymension DM70.
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 DM10 features Binding post type posts and Dymension DM70 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
