Im struggling to get a good box design that can place my existing sub (Dayton rss390-hf 15) in the closet and vent into the room. 4th order working within 11cf I get a peaky response between 20-40hz. Ported response is still a fantastic 20hz up and flat..But how does that then vent into the room. At least without a giant 15" hole in the wall?
the space
The sub shown can almost fit as it is behind that wall its currently in front of. Thats the location I plan to build the new box for. Its already the a/v cabinet so it works well. But I need the sound only going to the media room, not the room behind it.
Its a closet in one of the spare bedrooms I converted to hold the a/v equipment. The space below the shelving is 24" high, 20" deep and 42" wide.
Any ideas? My next option is a THT table or something because I dont want to lose any output, just try to keep the space functional. The existing box is a bit of an eye sore.
