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
Gold C250 6G and Platinum C250 3G have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Gold C250 6G sensitivity is rated at 87.5 dB and the Platinum C250 3G's is at 88dB.
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 Gold C250 6G and the Gold C250 6G 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.
Gold C250 6G can handle a max power of 300 watts RMS from the amp the whereas Gold C250 6G has a max power handling value of 250 watts RMS , 50 watts less than the Platinum C250 3G.
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
Both Gold C250 6G and Platinum C250 3G features dual binding post speaker terminals for bi-amping or bi-wiring.
