Hello everyone, I was using the search button, but I didn't come up with a solid answer. I'm hoping someone here can help me out. I'm looking for the recommend box size for 1 orphan sealed. I've read from other post that said the orphan are about the same as the SA-8 and likes the sealed box size of .17^3ft. I've also read a post from mike, that It needed .2 to .5^3ft, but I'm not sure if it was the recommended for seal or port. I actually wanted to try out they type of boxes and see which one sounds better to me. I do want to to try to make a passive radiator box, which I believe these subs were intended for. Here is the info from another post on this forum.
