Drivers
One of the fundamental differences between these two speakers is that Rebellion is a 2-way design whereas the Heresy IV 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.

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.
Rebellion can handle a max power of 200 watts RMS from the amp the whereas Heresy IV has a max power handling value of 100 watts RMS, 100 watts less than the Rebellion.
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
Heresy IV features 5-Way post posts which make bi-amping or bi-wiring possible. Rebellion has a Binding post which doesn't feature bi-amping/bi-wiring.
