I knid of still learning this SQ stuff. But if I'm thinking of the same thing. It means all of your crossovers are active electronic crossovers. Instead of passive crossovers. Advantages would be flexibilty in the crossover points. With most electronic (active) crossovers you can adjust the crossover points infinitly between two points. Where as with passives the only way to change crossover points is either through a switch on the crossover. Or by changing the impedence. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Any help ?
