Is HP (high power) mode a switch on the crossover?

Gavin,
A switch will be the easy way to implement this idea but I have in mind to have 3 binding posts, one for the negative connection, a positive for the DM(direct mode) and an alternate positive for the HP(high power). Both the low pass xover for the bass unit and the high pass xover for the mid unit are changed in the HP version. Both the crossover point and slopes will be effected.

Atjan you have no idea on just how keen and excited we are to get it done. I try to curb my enthusiasm in dealing with all our suppliers not to put to much pressure on them. It takes some serious self-control but we want to bring all with us and make them all part of the vision and project.

Atjan, have a missed a post or 2? Are you no longer in SA but in Aus?

Maybe not very exciting but here are screenshots of the envisaged port. It will be molded and then slot in a similar aluminum machined flare at the opening to the outside at the back of the speaker. I find port tuning so very critical every time that I do experiments. It is influenced by many factors and simulations are only a start. Besides the crossover resistance stemming from the bass/midrange inductors, I also found that stuffing in the working enclosures is very critical as well as external factors such as different amps and placement. Because of this, We will make the port, at least the 1st unit or 2, in such a way that we can fine tune the port almost as the last part of the design when all else is done and dusted.
