What size room are the MartinLogan Motion C10 and MartinLogan ESL C speakers good for?

The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:

Listening Environment* MartinLogan Motion C10 MartinLogan ESL C
Near-field Poor Poor
Small Room Average Poor
Mid-size Room Good Good
Large Room Average Good
Very Large Room Poor Average

(* Approximate Room sizes: Small < 100sq. ft / 9 m2, Mid-size: 100-220 sq. ft / 9-20 m2, Large 220-400 sq. ft / 20-36 m2, Very Large: > 400 sq. ft / 36 m2. Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual listening experience changes depending on floor height, room shape, surface materials, listening position, speaker locations, etc.)

In the following sections, we will get into more detail in order to better understand how the MartinLogan Motion C10 and MartinLogan ESL C compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers

One of the fundamental differences between these two speakers is that Motion C10 is a 2-way design whereas the ElectroMotion ESL C 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.

Driver MartinLogan Motion C10 MartinLogan ESL C
Driver Setup 2-way 3-way
Tweeter 1.0 x 1.4-inch 1 x 1-7/16-inch
Midrange - -
Woofer 2 x 5.5-inch 2 x 5.25-inch

Motion C10 features a 1.0 x 1.4" Folded Motion Ribbon Tweeter and 2 x 5.5" Woven Fiberglass Woofer with a Crossover frequency at 1000Hz and 2000Hz. On the other hand, the ElectroMotion ESL C features a 1 x 1-7/16" Folded Motion Tweeter and 2 x 5.25" high-rigidity aluminum woofers Woofer .

Frequency Response

Motion C10 has a frequency range of 63-25k Hz whereas ElectroMotion ESL C has a frequency range of 66-23k Hz. With a minimum frequency of 63Hz, the Motion C10 can go slightly deeper then the ElectroMotion ESL C's min frequency of 66Hz.

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

Motion C10 and ElectroMotion ESL C have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Motion C10 sensitivity is rated at 93 dB and the ElectroMotion ESL C's is at 89 dB. This 4 dB difference makes the MartinLogan Motion C10 a more sensitive speaker compared to MartinLogan ESL C, 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 Motion C10 and the Motion C10 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.

Motion C10 can handle a max power of 300 watts RMS from the amp the whereas Motion C10 has a max power handling value of 200 watts RMS , 100 watts less than the ElectroMotion ESL C.

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

Motion C10 features Binding post type posts and ElectroMotion ESL C 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. In this section, we are going to compare MartinLogan Motion C10's and MartinLogan ESL C's external dimensions. MartinLogan Motion C10 has external dimensions of 184 x 483 x 293mm ( 7-1/4inch x 19inch x 11-1/2inch ) whereas MartinLogan ESL C has external dimensions of 194.0 x 582.0 x 410.0mm ( 7-5/8 x 22-7/8 x 16-1/8inch) .

MartinLogan ESL C is clearly the larger of the two speakers. Its body is 99mm wider, 10mm taller and 117mm deeper than MartinLogan Motion C10.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited. The base surface area of the MartinLogan Motion C10 is approximately 1415.2cm2 / 219.4inch2 and base area of the MartinLogan ESL C is approximately 2386.2cm2 / 369.9inch2. The Motion C10 requires 41% less surface area than the ElectroMotion ESL C which gives it a small advantage on placement in tight spaces.

Weight Comparison

The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The MartinLogan Motion C10 weighs 10.70kg / 23.5lbs and the MartinLogan ESL C weighs 14.55kg / 32lbs. This makes the ElectroMotion ESL C 36% heavier than the Motion C10.

Here is a comparison of how Motion C10 and ElectroMotion ESL C's weights compare with the average, max and min weights in Passive Center Channel class.
