REL Strata III spikes


I have a REL Strata III sub. The interior of the feet have threaded holes that I assume accommodate spikes. Did spikes come with these subs when new. Assuming they did, is anyone using spikes and is there a noticeable difference? I'm wondering if spikes with floor isolator discs on a wood floor would make a worthwhile tweak.

The Strata originally came with spikes and Sumiko recommended to "not" use them. I don't with mine atop a sandbox.
Forget the spikes and forget the rubber feet. You may get better sound with your Strata III by doing what I did.

Turn it upside down and put a board on the now upturned rubber feet, with something weighty on top of that board. You may have to turn up the volume level a bit on the sub, but the bass should get tighter and more tuneful. I also found, contrary to common "wisdom", to keep it out of the corner.

Enjoy,
Bob
Talked with Sumiko awhile ago. Recommended not to use the spikes unless on hard wood floor and not on slab foundation.
