Anyone know what the minimum ported enclosure recommendation will be on the new OA 15's? They don't have it on the website anywhere and I can't find anything on google. I am seriously debating on getting in on the preorder on them but dont want to give up to much room. I'm wanting to do around 2.5 possibly up to 3 cf and run it off of a PPI P1000.1. I am more after SQ than SPL so I'm not looking to run a huge box.
