This is gonna sound odd (pardon the pun) but I can't even remember which search engine I used to find that info and I didn't see it in google (spent about 15 seconds). I'll try to find it again when I get home but there's a high chance my earlier sources were mistaking about the subwoofer.
And woodstock, I never said it was gonna sound good. I just said it would sound better (provided there was a subwoofer). But as an actual user of the laptop, your word is definitely better than mine.
