Decoupling for Cornwall IV's

I'm currently using six of these (three per speaker) and they definitely tightened the bass. They also raise the tweeters by 2".

For short money, it was worth the improvement. 

I looked at the isolation pad, it’s pretty specific, 63 hz. If your looking for complete DE coupling you need to go with springs, shocks and sorbothane gaskets between the suspension parts...

Just like a Rolls Royce.. :-)

Ah..........alas, I've only a Bentley!
I will nonetheless, look into your point of reference more carefully...
Thank you!
