I'm afraid I don't have any drawings, well except a few scribbles on a piece of paper.
I actually used "AJ Sealed Designer 2.0" software to calculate the box volume from the T/S parameters and then used the built in box calculator to work out the dimensions, constraining certain dimensions to make sure it would fit in the available space in the room. I then increased the volume by another 3 litres to allow for the Isobarik chamber and then increased the length by 10cm to allow for the sealed compartment for the amplifier panel.
All corners are half rebated to give additional strength and double the surface area for the glue. Corners are also screwed, mainly just to hold them together tightly while the glue set. Eventually the screws will be covered by the veneer. Everything was made from 18mm (3/4 inch) plywood except the speaker baffle board which is 18mm MDF. There was no reason for the choice of materials other than it was what I had lying around in the garage.
Once again, the drive units were used because I had them already in the loft. I originally bought them brand new about 10 years ago but never actually got round to using them. They are not the best drive units by any means but I am quite surprised how good they do sound. I may well replace them some time in the future with some better ones, but for now they are fine.
