One completed enclosure, minus the back panel, ready for finishing

It all starts when the UPS guy delivers three boxes of drivers, which contain 16 Vifa XT18WO09 woofers and 16 Fountek JP2 ribbon tweeters. The drivers alone weigh more than 100#.

When the drivers arrive it's time to go out and buy some mdf. This project requires three 3/4" panels and one 1" panel (for the baffles). It's best to have the lumber yard crosscut them about two inches longer than you will need; mdf is very heavy and this makes them much easier to carry.

Finally it's time to cut up some mdf. The panels for one enclosure are pictured in the background getting a test fit.

A closer view. The long panel inside the enclosure is a brace that runs longitudinally across the full width of the enclosure about 6' behind the drivers. Cutouts will be made behind each woofer.

Marking the cutouts for braces that will be placed between each second woofer. These are not called for in the plans, but braces like this have worked so well in other tall speaker projects that I decided to add them to the XT8 enclosures.

Measure twice, cut once. The cutouts for these woofers need to be precise, so it's best to do some trial cutouts and recesses on a piece of scrap mdf. Here I have done two and set one woofer into the hole - a perfect fit!

The final template with three woofer cutouts and a partial tweeter cutout that will accommodate three tweeters. Everytning fits, so it's on to the real baffles.

Preparing to draw out the woofer center points on one of the 1" mdf baffles.
