Spikes for Vienna Mahler?

I have a new pair of Vienna Mahler speakers and wish to replace the factory spikes with longer ones. The spikes that are furnished are 3/4" at best and do not penatrate the carpet. Any Mahler users know of scorce for spikes that can replace the shorter ones?
audiopoints.com has a large selection.
Orchard Bay acoustics can make you cones from 1 inch x 1 inch, 1.5 w x 1.75 to 2.25 L, or even 2 x 2.5 threaded to fit your speakers. As with anything in audio how much do you want to spend.
