You're asking the wrong question! Wattage alone doesn't tell you which speaker is better. Here's why:

* Wattage is power, not sound quality: Higher wattage means the speaker can potentially be louder. It doesn't mean it will sound better.

* Speaker size and design matter: A small 6-watt speaker might be plenty loud in a small room, while a large 24-watt speaker might sound thin and weak.

* Other factors: Sound quality depends on the speaker drivers, the enclosure, and the electronics inside.

Here's what to focus on when choosing an iPod docking speaker:

* Sound quality: Listen to reviews or demos if possible to judge how it sounds to you.

* Features: Do you need Bluetooth, aux input, multiple drivers, or a subwoofer?

* Size and portability: How big and heavy is it? Where will you use it?

* Price: What's your budget?

Bottom line: Don't get fixated on wattage. Look at the whole picture to find the speaker that's right for you.
