Rel Does Not Recomment Isolation Stands

jtcf, some subs like the REL bottom firing units can really rock the joint. I use to really like it, but things change. That's one, I don't drink so cranking the system is usually an occasion but not the norm.

Raising a bass unit UP is one of the thing REL does rather nicely. The BOTTOM sub just need a butt plate or slot load it and use and air bag to decouple. Stack 2,3,4 high, ALL are decoupled because the bottom one was. I like that idea..:-)

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.
