I've got a Tempest Driver, an Adire AVA250 amp, and two 3" flared port kits. I'm going to be building the Adire Vented Alignment as shown here: http://www.adireaudio.com/Files/Vent...plications.PDF I'm going to be using MDF board for this. I plan on cutting the corners of the sides of the walls into "L" shapes, so they will fit together nicely (called dado grooves?). I will be using only wood glue. Now most of this is clear to me, but when it comes to attaching the amp and the driver to the box, that's where I need some clarification. The box is supposed to be completely sealed, correct? How do I attach the driver and amp so I accomplish this? I remember reading something about weather stripping. I have silicone at my disposal. All around the edges of the amp plate is a kind of squishy foam. The edges of the driver are just metal. I understand that putting a screw into MFD may chip the board. The amp and driver both seem to require screws or bolts to hold them in place. How do I go about this? And when explaining, please use lots of detail, as I'm not much of a wood working expert. I'm thinking about drilling a hole through the MDF where each screw hole is on the driver/amp, and then using a nut and bolt to attach it (so there is no actual screw going into the MDF, simply a bold holding from the other side). But I'm concerned that the holes I drill will be too close to the opening for the driver/amp, and the MDF will break when I drill them, or tighten the bolts. Is it a problem if I put the amp close to the driver? (stick the amp at the bottom on the side of the box, and the driver is on the bottom) As for the legs on the box, how should I make those? How should I attach them? These 4 little legs will be supporting about 150lbs if I understand correctly, so they will need to be very strong and sturdy (in case I want to move the sub, the legs can't snap as I pull it across the floor). Thank you very much. Jonny K.
