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.

Both handle the same maximum of 120 watts RMS, though Studio 2 55IW is rated up to 120 watts and Phantom H-50 30-120 watts.

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

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.

Area	Better	Why
Bass	A	JBL Studio 2 55IW digs deeper - 40Hz against 52Hz.
Amplifier needs	evenly matched	Similar sensitivity (88dB vs 88dB) - both want much the same power.
Amplifier match	A	JBL Studio 2 55IW is the easier load at 8 ohms.
Headroom	evenly matched	Similar power handling (120W vs 120W).
Size	depends	Similar cabinet size - neither is easier to fit.
Expandability	depends	Neither adds bi-amping, a sub output or height drivers. JBL Studio 2 55IW sits in a wider range (15 models), so a matched surround system is easier later.
Price	A	JBL Studio 2 55IW is cheaper - $600 against $798, about 25% less.

A JBL Studio 2 55IW B DALI Phantom H-50
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 2 55IW is the easier recommendation: it leads on most of the measured areas and costs less. Take DALI Phantom H-50 if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 52Hz anyway, so judge these on the other rows instead.

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.
