I am (still!) working on my TLA speaker build. I have 2 cases of those NSB speakers PE used to have plus all the stuff to build it, I just need to find the time! Hopefully once the weather gets warmer I will be more willing to work in my garage on them.
I'm using some of the small dome tweeters in my project. I REALLY wanted to go 16 NSBs to a side with 8 of the tweeters but I think it's too tall for my room. I'm sort of following Thylanter's origianl design. I've got my router ready, and have played a bit with some small test boxes. I'll probably have a case left over (I honestly almost ordered 3 just for fun) so I'll have to come up with something else fun to do!
