burko Posted July 9, 2011 Report Share Posted July 9, 2011 I'm planning a build of 1 Fi BTL N2 18s off of two Crescendo BC3500s walled off in my truck, and I'm using the Torres Speaker Box Tuning Calculator. I'm wondering exactly what the "# of Common Port Walls" option means. I have about 52" of width to work with, so I'm looking for the port to be 50.5 inches wide, so it would span across the entire top of the box. I've been messing around a little bit with some of my options and I'm not quite sure what the option I mentioned is referring to. If someone could clear this up, I'd appreciate it.

bassfiend316 Posted July 9, 2011 Report Share Posted July 9, 2011 Its how many outside walls of the box are also port walls. If you go side to side across the top, it would be 3. Top, left side and right side. Link to comment Share on other sites More sharing options...
burko Posted July 9, 2011 Author Report Share Posted July 9, 2011 Its how many outside walls of the box are also port walls. If you go side to side across the top, it would be 3. Top, left side and right side. If that's the case, then why do I get the error message when 4 is input? What is stopping me from making a slot port that uses the the top, left and right sides, and bends at the back and continues down, therefore making 4 common port walls?

Lbox88 Posted July 9, 2011 Report Share Posted July 9, 2011 If you go to the torres box calc thread, he lists links for the number of common walls towards the bottom of the first post. UBL | Build Log Link to comment Share on other sites More sharing options...

Supercharged DCs Posted July 9, 2011 Report Share Posted July 9, 2011 That would be 3 common walls my good sir, not 4. At least that's I believe that's what you are describing. Bassless once again.

That's still 3 common port walls that bend to another box side is still treated as one wall because you're looking at the port as a whole. You can only have 1,2, or 3 common port walls.

You'll be using 3 walls, top left side and right side. -Zach-2010 Toyota TundraFull Hybrid Audio SQ 7" BDS on 37's 2000 Ford Expedition 160+ dB Green Turd -SOLD- Link to comment Share on other sites More sharing options...
