philrab Posted October 20, 2014 Report Posted October 20, 2014 What's your clearance between the port and the back wall? Looks a little close from the pic. 2015 Toyota Tacoma Build Thread 2007 Mazda 3; 5000K HID's, Kenwood Excelon KDC-X997, Infinity Reference 6.5 comps in front and coaxials in the rear doors, JL 320.4 four channel, Rab Designs built ported enclosure with an SA12, Kenwood monoblock, Redline Leater shift boot/e-brake boot/center console cover, JBR short shifter/shifter bushings/rear motor mount.

philrab Posted October 22, 2014 Report Posted October 22, 2014 it is a 4" clearance I like to have a port width of clearance between the port entrace and the back wall. Being an inch short may not be the end of the world, but to hedge your bets I'd throw a roundover on both sides of that side of the port, inside and outside diameter (so that in cross section, the wood would look rounded and have no sharp edges.) It'll change your tuning slightly (bumping up the tuning on the ported side just a little most likely), but turbulent air don't sound good. You could also add some external port and short the internal port to gain some port clearance, but that will change your net airspace on the ported section. Subs are going to displace into the sealed sections correct? 2015 Toyota Tacoma Build Thread 2007 Mazda 3; 5000K HID's, Kenwood Excelon KDC-X997, Infinity Reference 6.5 comps in front and coaxials in the rear doors, JL 320.4 four channel, Rab Designs built ported enclosure with an SA12, Kenwood monoblock, Redline Leater shift boot/e-brake boot/center console cover, JBR short shifter/shifter bushings/rear motor mount.

cherojeep96 Posted October 22, 2014 Author Report Posted October 22, 2014 yes as of now the subs are going to be displaced in the sealed section unless it turns out not to work well that way i might go with a slight ext port and round off all the edges and also put in the 45s in atleast the back corners
philrab Posted October 22, 2014 Report Posted October 22, 2014 Any time I see a slot/square port, roundover is my recomendation. That's what I do on all my enclosures. 2015 Toyota Tacoma Build Thread 2007 Mazda 3; 5000K HID's, Kenwood Excelon KDC-X997, Infinity Reference 6.5 comps in front and coaxials in the rear doors, JL 320.4 four channel, Rab Designs built ported enclosure with an SA12, Kenwood monoblock, Redline Leater shift boot/e-brake boot/center console cover, JBR short shifter/shifter bushings/rear motor mount.

thefourth Posted October 23, 2014 Report Posted October 23, 2014 Are you running 1 cu sealed for both 12s? Thanks alaskanzx5 I might just do thatI can recone a sub myself. About a year ago I took 2 12" power acoustic mofos and made one sub. I took the magnet and the motor off of one and j b welded it to the other motor and magnet. I had to wind my own voice coil so it would work. After I was done hooked up to 2 boss 5000w amps. And shattered my back and all my side windows came to this thread to recommend soundqubed and ct sounds. OP goes with soundstream. oh lawd.
thefourth Posted October 23, 2014 Report Posted October 23, 2014 I believe your sealed section should be at least 2 cubes. Thanks alaskanzx5 I might just do thatI can recone a sub myself.
