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.

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

A generation apart: JBL Studio 6 88LCR is the newer design, against a 2017 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.

Area	Better	Why
Bass	B	JBL Studio 6 88LCR digs deeper - 43Hz against 60Hz.
Amplifier needs	B	JBL Studio 6 88LCR is more sensitive (96dB vs 88dB), so it goes louder on the same amplifier.
Headroom	B	JBL Studio 6 88LCR takes more power (175W vs 100W) - more in hand in a big room.
Size	depends	Monitor Audio CP-WT240LCR is easier to place; JBL Studio 6 88LCR 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 88LCR sits in a wider range (15 models), so a matched surround system is easier later.
Price	A	Monitor Audio CP-WT240LCR is cheaper - $1,300 against $1,600, about 19% less.

A Monitor Audio CP-WT240LCR B JBL Studio 6 88LCR
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?

JBL Studio 6 88LCR leads across most of the measured areas for a fairly modest premium, which makes it the easier pick if the budget stretches. Monitor Audio CP-WT240LCR is the one to take if it does not. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 60Hz anyway, which makes the cheaper Monitor Audio CP-WT240LCR much easier to justify. Match it to your room: we rate Monitor Audio CP-WT240LCR the better fit for near-field listening and a small room, and JBL Studio 6 88LCR for a mid-size room and a large 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.
