I'm happy to report that one of my projects will get the go ahead on Saturday. A Tempest dedicated to music, which will be used with my Martin Logan speakers. After talking to Adire, they convinced me from changing my ported EBS design to an Adire Alignment setup. I'll deliver the plans to a local carpenter, who has been highly recommended for his exotic and unusual designs. I'll tell him to deliver an MDF box in the stated dimensions, and to use his imagination on the outside of the box. All I'm going to ask for is that the sub be finished with glossy black paint and a couple of coats of clearcoat People have told me to expect something out of the ordinary, so I'm happy (I think there will be some motifs outside the box, and stuff like that). So far, the tips I've been thinking on giving him are: 1) DON'T use screws on the box, but rather glue everything and clamp it. 2) Be sure to caulk the inside of the box. 3) Follow the inside dimensions perfectly. Is there anything I'm missing? Also, if someone thinks an AA is not an optimal design for music... now is the time. I still have a chance to build any other design (a Q=0.707 sealed box, perhaps?) I'm anxious to start this! Javier.
