Hello again,

I just had a question thread going about retuning my cabinet here.
http://www.hometheatershack.com/for...iscussion/53377-sub-replacement-now-what.html

When I had the sub apart I upgraded the bracing inside. This had been recommended to me when I first built it a couple years back. I actually did notice significant panel flexing at high output levels with the old build. The original build thread is here.

So I already had 3 oak braces coupling back to front. I also had 3 plywood gussets glued and nailed in. As I mentioned, the sides are big and would still flex at high volume. To fix this up I cross braced the 2 sides, plus top and bottom. I found some rough cut 1"x4" ash for this. Here are some pictures of what I am talking about starting with some before shots and ending with the new bracing. The new bracing is glued and screwed in.

It is not as pretty inside as many peoples' projects, but I know it was strong before and will be very strong now. And yes, many experts predicted I was under-braced, and indeed I was. Thank you again for everything.

I have not finished retuning the enclosure. I can't turn it up yet but I will let you know. There was never much flex at normal home theater listening levels, but I like to try stuff once and a while.
