Easily spiked my SRS 2, here's a link to good spikes

Rex81

I finally spiked my SRS 2. I avoided doing it for a long time due to the fact that I like to move speakers in and out a lot and spiking 150 lb speakers makes that a little more difficult.

But it's certainly one of the best effort/dollar/improvement ratios out there.

For anyone considering it, just do it. You'll be happy. To make it easier, I recommend these spikes as a cheap but good option. You can spend more, you can spend less, but I think this is the sweet spot. Get 8 tall, sharp come spikes for $25 shipped from Madisound. Extra bonus: because they're 1/4-20 thread, they use the existing inserts that are in the SRS models. Maybe others, I don't know.

I just lifted one end of the speaker off the ground, unscrewed the flat meta pads that are stock, screwed in the spikes, let the speaker down, then lifted the other side and did the same. Repeat for other speaker and I finished in under 2 minutes.

Glad it worked out for you..... Im not sure why, but i see the site you listed & to me those dont look sturdy enough for speakers over 100lbs. Maybe its just me

They'll reasonably dense and seem to hold the speakers sturdily. I needed tall ones for my thick carpet.

I've used those you can also get a bigger base to attach them to which also raises them up even more. They're pretty stout for what they are.

Randy, you have a point there. They look exactly like the ones I used for the 2Bs, which are quite a bit lighter @80 LBs. Hey if it works for him as it did for me all power to ya.

I also used the same spikes as the OP on my 2B's. I have walked them across the room on the carpet with no problems. That is putting the speakers total weight on one spike.

Yeah, Madisound offers a beefier option for 3x the price, (which still isn't bad) that is basically this spike screwed into a larger cone base so the speaker is sitting on a larger surface area if that's what you fancy. But I believe the threaded area is the same and that's what's handling all the load. Because they're using Polk's original insert, I have no doubt these will hold up just fine. Others may want to pay for the additional piece of mind of the larger set.

I used the cheapies.

The first couple of threads are doing all the work...the first thread is doing about 1/3 of it alone.

Using something that has a "head" on it actually makes the screw stronger. If we screw it in all the way and force it against the threads, we can preload the screw.

I'm not saying that we actually need to...the simple screw in type without the cone 'head' seem to work under most cases. It may just be that once they are in place most ppl don't move them. It would be the lateral forces that we should be concerned about.
