looks like im going to get started on the box for the inwall first. mtg90 is helping me by designing the network. he does this using pure mind power because hes that awesome. so basically i come up with a crazy idea. He makes it actually work
the goal with this inwall is as follows:
1. use the same TD12M driver with the DNA-360 as my mains
2. make box big enough for a tune that works well with a 80Hz cross over
3. stick out from the wall only far enough as absolutely necessary
4. be an attractive option for others that cannot do a false wall and are looking for a high performance inwall solution
After a few God awful Google sketches involving using half my front wall cavity as an enclosure, Matt and I decided a 1 cft. box would work best. this allows for a tune of 50Hz and an F3 of 80Hz (thanks Matt). the TD12M driver is just barley over 6.5" tall, so is the SEOS 12 and 360. we are using two 2" ports each 5" long. making the box 7.25" deep and then adding a double baffle will give everything about 8" of breathing room when surface mounted. that leaves plenty of room for some insulation.
i ended up with a box 14.25" wide. 34" tall. and 7.25" deep not counting the extra baffle. im going with a 14.25" width because 16" on center studs tend to be just 14.5 inches apart. the 14.25" width will allow for shimming if needed.
my local lumber yard (Mans Lumber in Canton, MI) is pretty awesome. i come up with a cutlist on an iPhone ap, call them up. order the material. email them the cutlist. and they call me a few days later when its done. pretty cool huh?
here is the cutlist i am using on this build
Td12m Inwall Project.pdf 77k .pdf file
two of the 12.75x5.75 pieces will be used for the top and bottom caps. the others i will cut holes in and use as window bracing. then all i have to do is cut out the hole for the driver and WG and im all set.
