REL Strata III spikes

It depends who you talk to at Sumiko, I was given contradictory advice in emails by two people there about whether to use rugs under the subs. I used mine on concrete [with rugs] with the cones and they worked fine. Of course I don't know what the stock spikes are like; I have found that the brass cones are much better than the stock steel spikes supplied with speaker stands; you would expect this as they cost much more and are obviously of higher quality.

If you do this use brass bolts.

I have two REL Stadium subs. They do come with spikes but I didn't get them either as I bought them used. I am using Star Sound cones on mine and it made a noticeable difference to me and others listening when we compared them with and without. I am a Star Sound dealer but am not sure of the current status of the company, the owner has had health problems in his family. But the cones definitely tightened up the bass.

I don't know for sure but the manual talks about using the spikes as if they were included. I talked to Sumico about them and they were clueless, suggesting I talk to a dealer. As I understand it they not only import REL but now own the company so they should know if anyone did. They have fallen a long way from what they were in the old days when I was a dealer for them. The cones I mentioned have a matching cup available for wood floors.
