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 DM30 and Dymension DM60 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Dymension DM30 sensitivity is rated at 93 dB and the Dymension DM60's is at 88 dB. This 5 dB difference makes the Definitive Dymension DM30 a more sensitive speaker compared to Definitive Dymension DM60, 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 DM30 and the Dymension DM30 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 DM30 and Dymension DM60 has the same power range of 50-300 watts.
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 DM30 features Binding post type posts and Dymension DM60 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
