With the current limits of USB power, wattage in any usb powered speakers is downright pathetic. Carrying around speakers that need a wall wart also makes no sence, since the goal is portability. Since firewire can output 12v... this opens up a possibility of using car amp IC's to power speakers ( of whatever design you come up with). Using this it is theoretically possible to obtain up to 12 watts of true RMS power per channel, which is certainly more than almost any but the most high end 2.0 speakers, and even those are powered by AC power supplies.
Does anyone know the current capabilities of firewire? Particularly on a laptop? It would at least need to provide about 2 amps of power wouln't it?
Is this safe, or is there a possibility of runing a laptops power supply by pulling too much power?
Please , any ideas/ thoughts here would be greatly apreciated-I am tired of having to spend over $50 on ehhhh decent enough sounding speakers because their "portable".
