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. 

@michaelc2020 I also heard about these isolation pads through Stereophile, I believe it was for the Volti Razz review. Thank you for the compliment on the system, I'm trying to keep it simple. 

@jbhiller I was using these with CW IV. I actually struggled with the CW IV placement to the point of almost giving up. These isolation pads really helped me and were a great low cost solution.

I also have a more expensive Townshend seismic bar solution; more effective but also way more expensive.
