Is it just the color difference?

Are there Specifications difference?

Anybody have Both Specifications to be able tell the difference?

Some say the 55 is louder but the printed specs for both boxes say they're identical, although the speakers are constructed differently the same specs are mentioned for both

So there's some tweaking going on, but JVC say's it's all the same

0 difference, it goes without saying 

The pc55 is better than the 550 because the speakers are better in the pc55...i have both

You stopped collecting boomboxes and moved to HiFi...your point is moot!

JK Reno!
