Closed back Khorns


I recently had my Khorns refurbished and veneered to update their look. While they were in the shop I had them close the back up to make a airtight box for the woofer. 

I moved them from the corners and the bass was amazing. 
Wondering if anyone else has done this. 
Thanks

That cabinet is sufficiently large enough to work well sealed with that woofer.
