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.

Studio 6 Theater can handle a max power of 150 watts RMS, whereas Motion XT CI XTW6 has a max power handling value of 100 watts RMS, 50 watts less than the Studio 6 Theater.

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.

Verdict

These sit in different price classes - JBL Studio 6 Theater costs roughly 1.6x what MartinLogan Motion XT CI XTW6 does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.

Area	Better	Why
Bass	B	MartinLogan Motion XT CI XTW6 digs deeper - 56Hz against 65Hz. A subwoofer would even that out.
Amplifier needs	A	JBL Studio 6 Theater is more sensitive (96dB vs 91dB), so it goes louder on the same amplifier.
Amplifier match	B	MartinLogan Motion XT CI XTW6 is the easier load at 8 ohms.
Headroom	A	JBL Studio 6 Theater takes more power (150W vs 100W) - more in hand in a big room.
Size	depends	MartinLogan Motion XT CI XTW6 is easier to place; JBL Studio 6 Theater is bigger, which usually goes with fuller bass. Your room decides.
Expandability	depends	Neither adds bi-amping, a sub output or height drivers. JBL Studio 6 Theater sits in a wider range (15 models), so a matched surround system is easier later.
Price	B	MartinLogan Motion XT CI XTW6 is cheaper - $1,600 against $2,600, about 38% less; arguably a different class.

A JBL Studio 6 Theater B MartinLogan Motion XT CI XTW6
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.

Which should you choose?

Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 65Hz anyway, so judge these on the other rows instead. Match it to your room: we rate JBL Studio 6 Theater the better fit for a mid-size room and a large room, and MartinLogan Motion XT CI XTW6 for near-field listening and a small room.

And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
