View Full Version : Need A Box Design

04-15-2007, 07:59 AM

i have been trying to design a box but seem to get it wrong, i dont have the knowledge to design a ported box correctly. i would be willing to pay for somone to design me a set of plans so that i can give them to a woodworker so that they could make the box.
i would just pay somone to build the box but i live in the UK and its going to be difficult to send it.

anyway i want a ported box for a RE SX 15, i have 30" width 17" height and 20" depth, i calculated that i have 4.73 cubic feet. i dont know what tuning i should have for that size box, but the RE internet site says 34Hz for 4 cubes.

so would 4.73 cubes be alright, as the driver is going to take up some box space.

also which way should the sub be facing, is it towards the tailgate or facing the roof.

Here you go 3.75 @ 34HZ w/46.50 sq/in of port.


Can't really do any better on volume of port/driver without compensating for each.

PM me for details.

its going into a golf mk4 2001, which way should the sub face, i was thinking of facing it towards the tail gate, but i have heard that by facing the sub at the roof towards the rear window you get a higher amount of db

as stated in my PM,

The box I designed is going to be the most ideal port / driver volume that you are going to be able to accomplish with the limited space you are working with.

As far the the sub positioning, with the design, you can plan the dirver on the top panel of the box. This is what I would recommend in a VW Golf.. driver up port back.
