This is exactly what I am looking for. So we will be waiting for these.
Its such a good idea for me and my space. I was going to use 4 parts express 1cu ft blank front box with 8" woofers and stack 2 of them per stand.
But I like this design a lot. It will be awhile before I would need them. I currently am waiting on my mini kit and once that is done then I want to build a set set of XLS Encore's.
