    I replaced the polyfill from my SRSs with Acousta Stuf. I have no idea whether it is an improvement because I made so many mods at the same time (yeah, unscientific, but it is expeditious!). However, somebody had filled my SRSs with probably twice as much polyfill as had been originally installed. Furthermore, they had filled the bottom chamber of the cabinets behind the PRs with egg-crate foam.

    In my 1Cs, which I'm working on now, I'm reusing the stock polyfill.

    Here's what the upper part of the cabinets looked like:

    I apologize once again for the screwy pictures; I couldn't figure out how to delete the "big" picture.

    For God's sake, Larry, I've learned something from you guys!

    Although I still need to figure out how to add, manipulate and delete pictures that I import into a post on the Forum!

    Of course I removed all that crap.

    Cheers, and have a great day!

    I need to decide on BH5 or Norez for the 2.3TL and place my order. Any suggestions?

    I can't remember which thread it was in, but I recall reading Face's Or maybe VR3's response that NoRez was better for mids, highs and BH5 was better for low end. I haven't used either so I cannot comment as to which would be better.

    Also, thanks Fred for your response.

    For those who have asked questions about installing BH5 inside SRSs or 1Cs, I have a couple of pictures of the insides of my SRSs that I took after putting in 4" wide strips behind the MWs and 2" strips inside the side walls of the cabinet. I did basically the same configuration in the 1Cs, except the strips behind the MWs were only 3" wide.

    There are also a pictures of the way I cut the BH5, which I found somewhat difficult to work with. I clamped a metal fence posts on each side of the cut line, compressed the BH5, and used a very sharp carpet knife to make the cut between the fence posts. It gave me a good clean cut, and was faster, even considering the set up time for each cut.

    I've also included some pictures of the BH5 on and in the 1Cs, showing the BH5 behind the MWs.

    The order of the pictures did not follow the way I intended to insert them. From left to right: Inside of SRSs, 1Cs with BH5 installed, BH5 through crossover opening in SRSs, inside of SRSs with BH5 installed on right side and back, four strips of BH5 on 1C ready for installation. Bottom row pictures: one cut strip of BH5, set up for cutting one strip of BH5.

    Nice pics - and great cutting! When I did mine I used titanium coated "cuts everything" scissors and a utility knife. The edges weren't as straight and smooth.

    The pics do a good job illustrating the installation.

    drumminman,

    Thank you. I'm glad I may be able to give back a bit to this Forum. I have certainly benefited greatly from the work and postings of others.

    Onward and upward to better and better sound, especially from our Polks!
