Spikes for my Polk Subs

I broke off one of the rubber feet on one my Micropros somehow and I decided to try spikes. Problem was that all the spikes I researched needed for you to do some drilling of larger holes in your sub for the socket part of the spike to fit Too much of a hassle. I called Polk and they said the threads on their sub feet was 3/8". I saw these on Parts Express, ordered them, and they work perfectly in the sockets already in the sub. At first, I though they didn't look cool enough but after I installed them on my subs you can't see them anyway. They work perfect! Just thought I pass this on. I assume they'll work with any sub posts or spikes that are 3/8"

    I called Polk and they said the threads on their sub feet was 3/8".

    The DSW Pro subs use 6mm threads.

    ecause

    It's hard to say, because I got the Sherwood R-972 (Trinnov mode) almost the same day the spikes came in, and when I ran Trinnov the subs changed so dramatically that I don't know how much could be attributed to the spikes. I do know that the subs don't move anymore like they would sometimes do on movies like U-571.
