B&W 802D Floor Spikes??

The reason I was asking is they are an expensive option
for the 802, and I know what spikes do in general, but wanted
to know what they bring to the 802 in particular. I'm sure it's the same standard things, but wanted to see if it was
worth the extra $$. I normally do not use spikes because they never penetrate my thing carpet, but the monster 802's will so!?

Thanks Jppenn! I called my dealer and left a message
about this. I told them I called B&W, and they said "yes"
I was eligible for spikes, but I did not know what they meant by that, but now I think I do! :o)

Thanks again!
