Boy am I tired. I still need to add a brace between the two woofers and foam, etc but should be ready to do some measurements next weekend. Cheers, Paul.

You've been busy, Paul....

And I'm sure that's a good kind of tired your feeling- the result of solid accomplishment!

Maybe I'll have a little of that feeling in a couple of weeks.

What drivers are going to be filling those holes in the baffles? Would there be a Morel Midrange in that mix?

Looking good! :T

Yup that's an MDM-55 mid-tweeter, dual RS225s in parallel, and a Seas 27TAF/G 3/4" metal dome tweeter. I couldn't cut the port hole until that new PE 4" outer flange comes in. They don't have measurements for it up yet, and it doesn't arrive until mid-week. That will give me time to make sure it's all sealed up nice and tight, put that other brace in, foam the walls, sand, make everything flush, etc. Still a lot of work but it's getting closer to the point I can measure.

Paul,

How do the simulations look? Imp. FR phase etc.

Hi Jed,
I only had measurements for the RS225s and did a pseudo model using a 4th order acoustic at 900hz. The breakup mode was down 40+db and went down from there. I don't have measurements for the others yet so I'm not able to start modeling. FWIW, as it will probably change, the main woofer filter I have modeled is a 3rd order electrical which becomes a 4th order acoustic. Looks like about 90db maybe 91db efficiency. I know it's all going to change once I measure them on the baffle though :-). Maybe next week I'll have them measured. Just hard to do during the week day. As you can tell, I'm pretty excited because I got all the parts cut, and one box pretty close over this weekend. I'll keep everyone abreast as things develop. I just get worn out sometimes and it's weeks before I get back to it :-). Cheers, Paul.
