Okay this should reel in a good amount of people from search engines I feel :D

I was looking around for thread sizes to speaker feet/spikes because I'm going to have to buy 8 of them soon and had to do a lot of searching and finally found something definitive. These may vary with time but it should still give people something to go on.


Please inform us if we have missed one.
This list is based on the best information we have from the different loudspeaker manufacturers listed and our customers. It is possible that some speakers may have non-original manufacturer inserts installed on your speakers or that your speakers had different inserts used on a select group of speakers made.

It is always a good idea to double check, see our Speaker Spike FAQ page for more information.
