Not a whole lot to say in this update,
This is all the easy stuff done, now to measure all three drivers and come up with a Crossover!
- applied two coats of Osmo oil to the boxes
- put some 2" wool batting on the inside of the boxes
- installed the drivers so I could start measuring for a crossover (upper back is a dummy back with two terminal cups just for measuring)

Measurement time,
Any suggestions or hints about the XO would be appreciated.
I have yet to listen to the XO, so I have no idea if this will be okay or sound like crap yet, parts are supposed to arrive tomorrow and then I can start to play around in the real world. About 1 week left, no rush, no pressure...
Yes, I am using high DCR air coils, I have other options in the tool box if this turns out to be a bad idea.
I was trying to keep the parts count down for the mid and tweeter as space is limited for where I wanted to put the board with those components. I did have more complex versions of the XO, but this was the least amount of parts I could use and still be happy. Might not have needed fourth order electrical on the woofer, but I have lots of space in the bottom compartment and wasn't as thrifty with the Iso woofer low pass circuit.
Comments good or bad welcomed!

With the measurements done and some tweaks done to the crossover, it was time to listen to it, tweak a little more and then build them.
Never having really thought about it before, a three way has double the filters of a two way, and with the drivers I am using, it added up to a lot of parts.
Pic of mess on the floor as I try out parts for the XO.
Pics of building a crossover, pretty normal stuff.
Couple shots of speakers all ready to take to InDIYana tomorrow.
Finished with hours to spare....
See you there!
