High Frequency

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
Heresy IV is a 8 ohms speaker compared to the L100 Classic which has a nominal impedance of 4 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the L100 Classic can provide this impedance level.
These two speakers also have different sensitivity levels. Heresy IV sensitivity is rated at 99 dB and the L100 Classic's is rated at 90 dB. This 9 dB difference makes the Klipsch Heresy IV a more sensitive speaker compared to JBL L100 Classic, hence will play louder with the same amount of watts.

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.
Heresy IV 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 L100 Classic.
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. L100 Classic has a Five-way gold-plated binding posts which doesn't feature bi-amping/bi-wiring.
