Test Ports
|
For round one of the testing , seven test ports were built
The ports are made from PVC pipe, with a 270mm flange at each end. One or more smaller supporting rings are utilised, depending on the construction of the actual flare. The MDF pieces were glued together with PVA glue, and the PVC pipe was glued into the MDF with epoxy resin. The mounting end of the flare has a bolt pattern the same as a 10 inch driver, and is stepped so that the flare lines up with the inside face of the box. |

The ports have a stepped mounting flange so that they line up flush with the inside face of the box, as shown in this picture.

For round two of the testing, another eight ports were built.
The same construction method was employed for the round two ports, except that a larger 360mm mounting flange was required |
