I got my son a pair of $30 bookshelf speakers and an APA150 amplifier, and when he was showing me the model he finished last night he had music playing, and I couldn't help but be impressed for a $30 set of bookshelfs and a $130 amplifier how good they sound, plugged into his laptop with a 3.5mm cable....
These speakers should be the go to for any budget systems surround duty.... and when paired with the apa150 and an ipod they make a nice little mp3 system... Anyway just figured I would share....
