Drivers
One of the fundamental differences between these two speakers is that Grandis GR6T 6.5" 3-Way High Fidelity Tower Speaker (SINGLE) is a 2-way design whereas the Motion XT F200 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.

Grandis GR6T 6.5" 3-Way High Fidelity Tower Speaker (SINGLE) has a frequency range of 30-42k Hz whereas Motion XT F200 has a frequency range of 27-25k Hz. With a minimum frequency of 27Hz, the Motion XT F200 can go slightly deeper then the Grandis GR6T 6.5" 3-Way High Fidelity Tower Speaker (SINGLE)'s min frequency of 30Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Grandis GR6T 6.5" 3-Way High Fidelity Tower Speaker (SINGLE)
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Grandis GR6T 6.5" 3-Way High Fidelity Tower Speaker (SINGLE) and Motion XT F200 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Grandis GR6T 6.5" 3-Way High Fidelity Tower Speaker (SINGLE) sensitivity is rated at 85 dB and the Motion XT F200's is at 92 dB. This 7 dB difference makes the MartinLogan Motion XT F200 a more sensitive speaker compared to Aperion Grandis GR6T 6.5" 3-Way High Fidelity Tower Speaker (SINGLE), 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 Grandis GR6T 6.5" 3-Way High Fidelity Tower Speaker (SINGLE) and the Grandis GR6T 6.5" 3-Way High Fidelity Tower Speaker (SINGLE) 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Motion XT F200 can handle a max power of 600 watts RMS, whereas Grandis GR6T 6.5" 3-Way High Fidelity Tower Speaker (SINGLE) has a max power handling value of 500 watts RMS, 100 watts less than the Motion XT F200.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
