Rel Does Not Recomment Isolation Stands

Lifting speakers off the floor, subs or floorstanders, will alter the frequency response as heard at the listening position. I think of this whenever I read a post where in someone praises the practice of placing things under speakers for isolation, etc, and wonder how much of the change is due merely to the elevation, albeit small yet extant. FWIW.

REL is wrong plain and simple, They will put 12 coats of lacquer but won't cop for a set of 10.00 springs in bulk... Cracks me up.. BLING and glitter sells. What actually works you have to train people about.. Nothing changes..

I like both or course, Bling and Springs.. LOL

As far as raising the speaker yes it can be an issue, I'm actually dealing with a tweeter that use to burn a hole in you. By raising the speaker 1" and turning the tweeter 90 degrees, I was amazed.. Things just worked.. 

Engineer, NO! Mechanic YES..

The HSU subs that I have now perform worse when I've experimented with isolating them and raising them up.They seem to be engineered to perform at their best close to the floor and on the feet that come with them.

I understand. As I said, I was somewhat shocked when I learned this. From an engineering standpoint, it seems wrong. However, I have had them for 15-20 yrs and they sound great to me. Integrating with the speakers is very easily done too. Once they are setup, they add much more than just deep bass. That said, I’m still thinking of the ramifications of this " Controlled Rattle" system of integration.

I’ll probably file this along with the cables which also make a difference despite but don’t measure good

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..:-)
