Just seeing that last pic brings back memories of all the scrapes and cuts all over my hands from scraping that crap out of several X-series speakers built by AV123. I didn't even bother for my Statiks. I just upgraded the crossovers.
Exactly. Even with a putty knife, I had to get in there with my bare hands to pick and tear a lot of that crud out of there. A bunch of scraped up knuckles, sore finger tips, cracked/split finger nails, etc, etc. It took more time to remove that crud out of just one enclosure than it did to upgrade both crossovers from start to finish.
I tell you what though, installing that No-Rez was well worth it. It greatly improved the speed, tautness and detail in the upper bass and mid-bass. The bass didn't get any deeper, but due to the improvements just mentioned, the X-Statik's became more visceral, impactful, and definitely more "up to speed" with the open baffle section, making it a more complete package from top to bottom.
If I had to do it all over again and go through all of the pain and aggravation again, I most certainly would.
If you're still using your X-Statik's, I'd highly recommend doing the No-Rez. These speakers definitely benefit from it in a big way.
