Thanks very much for the reply - I will be putting several coats of lacquer on the baffle once I have finished working it. I got a pair of 6" precision ports that I am going to install recessed into the baffle, such that the face of the port is flush with the baffle (rather than sitting proud of it). I am also planning to back mount the 604s, and put a 45 degree bevel (eased) 'flaring' to the face of the baffle. There are not a lot of elements, but doing them right is going to take good planning and plenty of time to assure precision.

In this case, the journey is as much fun as arriving at the destination.

regards -- Roger
