thefourth Posted June 28, 2014 Report Share Posted June 28, 2014 Have you tried designing with 2 common walls? I see you have a 3" external port, but no port walls? 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.

MACnonsence6 Posted June 28, 2014 Author Report Share Posted June 28, 2014 shit thats what the 3 should be in not where its at my bad. 3 common walls would be an L port though like i have sketched in paint correct?

MACnonsence6 Posted June 28, 2014 Author Report Share Posted June 28, 2014 so then if my calculations are correct this is how its built if an L port like in paint has 3 common walls so im tuned rather low I picked up an MTX Sw1212 powered subwoofer today.

MACnonsence6 Posted June 28, 2014 Author Report Share Posted June 28, 2014 i think im going to build another box to the effect of something like this using full thread rod and a small piece of mdf for bracing as to not take up alot of space but this should give me enough space the right tuning and just about enough port area. could anyone offer any advice as to other ideas for these subs tantric said 2-2.5 cubes each tuned to low-mid 30s then keeping port area 14-16. this is going in a trunk car with subs and port forward I picked up an MTX Sw1212 powered subwoofer today.
