I have a Logitech LS21 2.1 sound system I use for my PC. It comes with a small down firing sub-woofer (4 inch driver). Right now I have the sub sitting under my computer desk. I'm using it as a footstool but its not very comfortable lol. I plan to get one of those ottoman / footstool but I don't want it to get too cramped down there. I just want to know if it's okay to put the sub inside the ottoman? Will there be any issues with heat or sound quality? Thanks.
Here are pictures of the sub-woofer and ottoman I want to get:
