..... My wife drives a 2007 BMW X5 and the "Premium Sound" upgrade in the Harmon Kardon has a MUCH better sub than the B&W. I love the highs. Just don't think the low end is great. I had a very nice aftermarket system installed in my previous cars so I am spoiled I guess. That being said, this is as good as the premium sound HK system in my wifes car. I honestly just thought the B&W system would blow it away, but in reality in does not......
Same feel here, the sub of B&W is not strong enough.
