I have no experience with the Tylers, but many speakers require a break in period, sometimes a very long one. That may be one possiblity.
Also, apparently the B&W's may have greater bass extension than the Tylers, so it may be you're hearing more of the highs.
I was curious, so I looked at these reviews:

Hope this helps.
