I have been having bad unloading issues with every box i attempt for my new XL m2 12s. I gave up Saturday afternoon and emailed several builders/designers that afternoon. I was not expecting a response till Monday at the least, Evan emailed me back Sunday morning. Very knowledgable, helpful, and customer service has been above average. I'm sure this box will fix my issues and bring life to my first big 5K build and make it something to represent DC soundlabs to the fullest.
I just wanted to post this for the ones still up in the air about choosing a designer. This is my personal opinion so far.
