shamless plug...but heck yea. My best 'test' is my 17 year old son. I took one home, and he immediately took his whole home system and threw it in the garage. It plays to 40, and at 18-20 he's knocking crap off the walls!
The passive radiator adds bass, where most home docking stations don't.
Check Amazon, they offer the best deals on them, and fast shipping!
The IK is for Ipod, and there is a ZK for Zune.
Then for the bedroom or kitchen, check out the smaller IK350 ( also available battery pack) and Ik150 alarm clock
<had to plug that in there>
