Specifically the first and second gen speakers on the 15.4"ers. I want to do a comparison to what I currently have on my 2.33Ghz MBP against a new computer I unfortunately can't play with first. I've spent the last few weeks looking and even in the maint manual for the thing there is no mention of W for the speakers. The best I've been able to find is a part number on http://www.welovemacs.com/9227192.html Not even a peep about its specs. Bah! Anyone?
