ictponder Posted March 7, 2018 Report Share Posted March 7, 2018 I'm limited to 25 cu.ft net for 4 x zv.5 18's on 10k 6" Kerf Torres calc = 33hz Width = 46" Height = 6" Length = 13.25 (9" straight parts internal roundover ) With this setup I'm just barely on the minimum side for port area (276in.sq) but i should still be under 30 meters per second. Should I raise the port another inch and get less compression (35hz tune) or will this be ok? I wanted to tune at 30 but limited space and kerf design won't allow it. Pink area is port volume. There is more bracing for subs, it's just hidden in this image. Link to comment Share on other sites More sharing options...

Knocker Posted April 7, 2018 Report Share Posted April 7, 2018 You could always do four 15's or three 18s and not have to worry about fighting for space. Cone area is nice but properly ported enclosures with happy drivers in "optimum" airspace is better in my opinion. "Optimum" depends what you want. If you want sq then smaller ported enclosures have flatter response and less group delay although require more power due to less efficiency . Larger enclosures will have a larger peak at tuning, require less power due to higher efficiency, and get louder. Unless you're chasing 160s I think four 15's or three 18's is plenty of slam when installed and tuned properly. Link to comment Share on other sites More sharing options...
ictponder Posted April 10, 2018 Author Report Share Posted April 10, 2018 He already purchased the subs so I have to make it work. I am mostly concerned with the port volume and if this design will cause too much velocity. I can make the port slightly bigger but since I can't make the box any bigger I'd have to go from 33, which is already king of high for what he wants to 35. This design will be over 30m/s Link to comment Share on other sites More sharing options...
