Parts Express Speaker Cabinet 3/8 Toe Spike Set (2 Packs of 4)

Worked as described. Installed them on my Infinity subwoofer. This is an inexpensive sub so cabinet is particle board. Care must be taken to not strip out. Threads were a bit loose as other reviews describe but overall it wasn’t a problem.

These did the job on my secondary system with PSB speakers. I bought the towers used on Craigslist and the guy did not have the spikes, so I ordered these (mainly because of cost). They are 1/4" 20 threads and pretty long. they worked fine. I would not use these on a hi-end speaker however.

Worked great! Same diameter as the original so easy fit.Had to shake the spike back and worth if the threads stuck while screwing them in to continue to thread them. Not a big deal.Like how they are longer and pointier spikes then the originals.Get your speakers level and point those tweeters at ear level for perfect sound!

Nothing fancy, just good quality spikes and threaded inserts with locknuts. Whn properly installed, they work perfectly.

Worked well for me.

I wish it was possible to give zero, or negative stars. These spike feet are the worst quality product I have purchased in a long time. I purchased two packages, for two speaker stands. In the first package, 3 of the nuts and inserts were properly threaded and went together fine. The 4th insert was not properly threaded, and not of the threaded spikes would go into in very far. I spent a LOT of time getting the threaded chased in that one insert so it would somewhat work. In the second package not a single one of the inserts that go into the wood was threaded properly. The nuts would go completely up and down the threaded spikes, but none of them would screw into the inserts, not one. I wasted a lot of time, and damaged the paint on all four spikes by the time I was able to get the spikes to thread into the inserts, and that was only by using a pair of pliers.Obviously the quality control wherever these are made is horrible or non existent. I recommend everyone find different spike feet from a different source. I have ordered directly from Parts Express in the past, but after this experience I may never order any of their products again.

These are fine. Unlike some other low-dollar spikes,.. the threads are done well enough that you can turn them by hand when leveling your speakers.As others have mentioned,.. when using them in MDF type wood (what most speakers are made of),.. the base tends to unscrew from the wood, instead of the spike unscrewing from the base. Mainly this is when you've tightened the lock-nut, and are trying to loosen it to make an adjustment.So I recommend not tightening the nut until you are all done leveling. Perhaps just leave them finger tight forever.OR,.. what I which I had done is have some epoxy ready when I first installed them. Screw the bases into the wood,.. then back them out a bit,... put some epoxy on the threads and tighten them back up again. Then they should work as well as anything at any price.

They fit Martin Logan Motion 12s. They are pretty tall, but I’m using them as carpet spikes and we have deep carpet, so perfect for my needs.

The previous reviews were correct, these are in fact complete junk. Running a 1/4-20 die over the treads helped significantly, and after that... they are STILL junk. Good luck finding a better quality equivalent though. I tried extensively and came up empty, so these will have to do :(.
