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
Expression ESL 13A is a 4 ohms speaker compared to the Illusion ESL C34A which has a nominal impedance of 6 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 Expression ESL 13A can provide this impedance level.
These two speakers also have different sensitivity levels. Expression ESL 13A sensitivity is rated at 91 dB and the Illusion ESL C34A's is rated at 90 dB. This 1 dB difference makes the MartinLogan Expression ESL 13A a more sensitive speaker compared to MartinLogan Illusion ESL C34A, 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.
Expression ESL 13A and Illusion ESL C34A has the same power range of 20-600 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
Expression ESL 13A features Binding post type posts and Illusion ESL C34A has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
Physical Specs
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons.
