Rel Does Not Recomment Isolation Stands

"Even though I am NOT electronics engineer I think this is an interesting subjet..."

Since we're dealing with what sounds "good"-that alone is debated  endlessly, Engineering white papers docs, graphs, charts etc. only go so far. 

Anything aftermarket, best to just try and decide with your own ears.

Thanks for posting this, @artemus_5. I’m shopping for a sub, and REL was at the top of my list. The sub is going to be on a suspended floor, and any rattle will be unacceptable. I think it likely that I would buy an isolation platform, but if using it means the sub doesn’t perform satisfactorily, then I won’t use a sub.

@tablejockey "best to just try and decide with your own ears” Correct, if test is blind (listener does not know which specific cable is used). In 99% opinion-reviews, cables are ranked by “looking good more expensive is better point”  not performance.

That reminds me, I need to order some SVS isolation feet!  Thankfully I don't own any Rel subs, so they should be great with the ones I have.

@jimcrane

I have been running Rel’s for 15-20 yrs. They sound great and integrate extremely well. No worries about performance...unless you isolate them. I wouldn't give up on them

The secret is to keep the crossover point as low as possible. Volume should be just enough to blend with the mains. They make the mains sound even better.
