Need speakers that can rock with just one watt? You found da place.

Don't go by the 1m/1w sensitivity, you have to go by 1m/2.83v, as all the drivers will receive the same voltage. 98dB/1w is 2.83v into 8 ohms, but it's 4v into 16 ohms. So if they're both rated 98dB/1w then the 16 ohm driver will have 3dB lower sensitivity with equal voltage input. Padding down a tweeter with a resistor LPad is no biggy, but with a full range or woofer the resistor power requirements could be substantial. OTOH if the woofer has higher voltage sensitivity that would help offset the need for baffle step compensation.
