xpoppadaddyx Posted June 29, 2016 Author Report Share Posted June 29, 2016 Your sketchup doesn't match what you have in Torres. In Torres you have the port as 16.5" x 3", but in your sketchup model your port looks to be about 33" wide. Your sketchup doesn't match what you have in Torres.

I don't have Torres on this terminal to plug in the new dims. Do you think this will work? 2002 Chevy Trailblazer (Build) 2013 Nissan Altima (Build) Poppa's YouTube Channel Poppa's FB Page Poppa's Instagram Link to comment Share on other sites More sharing options...

ShadeTreeMechanic Posted June 29, 2016 Report Share Posted June 29, 2016 How close is the port to the back wall? The back wall might add to the port length and It looks like the brace on the port entrance might also. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon) Link to comment Share on other sites More sharing options...

ckeeler11 Posted June 29, 2016 Report Share Posted June 29, 2016 You don't have enough port area you will have port velocities around 120 ft/sec. Which will kill output and cause port noise. you want to get to 80 sq. inches of port area or more. Link to comment Share on other sites More sharing options...

Which will kill output and cause port noise. you want to get to 80 sq. inches of port area or more. You are correct. How would you increase that number using the model? To increase port area you need to increase the height and width of your port. This will also require you to increase the length to keep tuning the same. You can probably get away with as low as 70 sq in of port area, but I wouldn't want to go below that if it can be avoided. A couple other things, the way you have the port layed out in your most recent pic, its a 1 common wall port instead of a 3. You should add in the woofer displacement, which in your case is .234 cu ft. A double baffle would be a good idea as well. Here is how your Torres should look before you start figuring out the port: What vehicle is this going in? You are probably going to have a bit of a challenge fitting the port in this box. Unless you can fire the port out the side, pretty much the only place to put it is along the top like you have it. To get the port area you need this is probably going to result in a really inefficient high aspect ratio port, which is significantly less than ideal.

ckeeler11 Posted June 29, 2016 Report Share Posted June 29, 2016 To help with port length you could tune a little higher. 31 is pretty low look to around 35. Link to comment Share on other sites More sharing options...
xpoppadaddyx Posted June 29, 2016 Author Report Share Posted June 29, 2016 It will be going in a Chevy Trailblazer so I figured porting this way wouldn't be an issue. It will be double baffled for sure. I was thinking of a couple of areo ports but I seen where you like slot ports better and as do I. I'll plug in everything you said when I'm at my terminal and post back up with a new model.
