Center Slot ported box for 2 Rockford Fosgate P3D4's, tuned for everything from rap to country...35hz???

Ok...well I built the box over this past weekend.  It was really pretty easy.  I can't wait to see how it sounds.

 

All parts were cut out using the table saw, I did have to trim the longer pieces to the correct length with a circular saw and fence...but no biggie.

 

 

I started by laying out where things were going to go.  This helps pre-drill holes and also allows you to double check the port spacing at all points.

 

I started assembly with the interior port walls.

 

 

Next were the bottom and sides.

 

If you have never used these clamps....just buy them.  They are worth every penny!!

 

Here we are almost completely done.

 

 

Just need to put in the wire and mount the subs and it will be read for a trial run.

That is superb work sir, it reminds me of how this forum was back in it's heyday. If anything I would remove some of the damping material close to the port inner ends as it may affect performance and tuning somewhat, something like 2-3 inches each side.

Thanks I will do that when I take the subs out for finishing the box exterior.  I am thinking I am going to Bondo all the screw holes, route all the edges and have it sprayed with bedliner.  I normally carpet them...but I think for this application I had rather have the bedliner finish.

 

It sounds really good so far.  I have not had time to set the amp gains with my oscilloscope nor have I tuned the whole system yet.  The box does not require much power to get really loud.

 

Thanks again for all your help!!!
