Only too much power and too much abuse hurts speakers. While you could possibly do damage to a tweeter or fullrange speaker by over-driving an under-sized amplifier into more of a compressed/continuous mode, it is very unlikely that you would hurt a subwoofer with that voice coil capacity by under-powering it to that degree. The sub simply will not come close to its potential and a smaller amplifier can reach its limit earlier when driving a woofer like the L7 which is pretty darn demanding.
