Front or Down Firing Sub

I know that there have been discussions of the merits of front vs down firing subs, and ported vs sealed. Mine is just a little different. I have a REL Storm III down firing ported sub which for placement reasons I would like to rest on its side (with proper feet support) and use front firing. Will this work or is there something in the design or the mechanics such as support of the magnet when sitting vertical that will cause problems.
