Howdey guys,

I'm looking to get a pair of loudspeakers to crank some rock and rap mostly.

I already have a Harman Kardon 3490 which will be powering whatever speakers I end up buying.

I host a lot of parties and like to play music loud.

The room I'll be playing music in is my carpeted living room and it's about 30 ft x 30ft.

Anybody have any opinions on these?  http://pittsburgh.craigslist.org/ele/4114318172.html

Or does anybody have any reccomedations on something fairly cheap (less than $500) that should fit the bill?

Thanks in advance guys!
