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 and Dymension DM10 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Dymension DM40 sensitivity is rated at 87 dB and the Dymension DM10's is at 90 dB. This 3 dB difference makes the Definitive Dymension DM10 a more sensitive speaker compared to Definitive Dymension DM40, hence will play louder with the same amount of watts.
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 DM40 and the Dymension DM40 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 DM40 can handle a max power of 250 watts RMS from the amp the whereas Dymension DM10 has a max power handling value of 200 watts RMS, 50 watts less than the Dymension DM40.
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 Binding post type posts and Dymension DM10 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
