[QUOTE="audioholic, post: 672926, member: 549629"] If you understand that sound is merely waves within the air molecules, and that a speaker creates these waves via its back and forth motion (being very basic here heh), by 'displacing' the air, you'd then realize that the big issue in how loud you'll get isn't about power ratings or even efficiency specifically, its about who moves more air. The driver's excursion abilities, power ratings, efficiency and enclosure design all play a role in this, but ultimately its who moves more air that wins. Therefore, when you ask which would be louder, the 500 watt setup or the 1800 watt setup, all other things being equal, as squeak said, its in the 'all other things' that are equal where your answer to whom is louder lies. If they are both displacing the same amount of air when all is said and done, they will both have the same SPL, even if one is running 100X the power, or one is in twice the sized box, etc. [/QUOTE]
