BSW Midranges... got cold feet

[Sablotny]

I had a bit of time yesterday to start my Stage 1 speaker upgrade (thanks for the great deal Halston), and figured I'd do the easiest part first- the dash midranges. Upon removing the stock drivers, however, they didn't look as cheap as I expected. Decent butyl surrounds, with a bigger magnet and seemingly longer excursion that the BSW units. I was also concerned that there are already high pass filters in the stock leads, the BSW units come with another capacitor, and I didn't like the idea of wiring these both up. So- can anyone tell me if the BSW units truly sound better?
