After a about an 9 months gathering and sifting of info, i finally got started on my build.
Decided on Ron's Austin 166 for the new home to my 168ES drivers.
That said, this is a tough build for a non carpenter mofro like me.
It will be slow and painful, any words of wisdom are welcome.
Cheers
Ed

!0/4 Dave picture to follow!
I need advice on using a joiner, are the bisquets supposed to fit tight in the slots or loose and they hold when glued?
Thanks

I need help here. 😕
The 166E has Vas 45.11 / Qts .21
The 168ES Vas 23.7 / Qts .26
Does the CC need to have less volume for the 168?

Measure three times, cut once!

I have already botched up a couple pieces trying get the angles right. Got pretty frustrated, then finally got a method that works.

Dave, I searched and read a ton, found lots of talk about the es-r volume adjustment but not the 168 sigma. Maybe I passed it up some how.
An externally hosted image should be here but it was not working when we last tested it.
I'm sure it was discussed, did you seacrh the FR Forum (might need to dig into the archives). Tony "layertine's" curcy Austin used FE168eS.

Thanks Dave, here & there... been so busy with 2 jobs now 😕
I think i missed out lots here. The last speaker build i did was that Lab12 tapped horn sub.
other CNC activity (off topic): Made 1/2" T-Rex for Halloween '09
Mr Ed, would really like to see more pics & good luck with your build.

Tony, how do you avoid squashing the pumpkins in the CNC? 🙄
cute job on the T-Rex
Tony your layertones have been very inspirational too me 
The Trex is cool too.
I am a little out of my league trying this build so its going slow, I have made a few mistakes but over all it will work out.
I am still confused on the chamber size, even after sifting through all the threads for the last 45 min. It could be not seeing the forest for tress...or input overload, as I am a pretty tired also. I will review tomorrow again.
I did get one more board glued up today🙂

"A rough guess is that the 168/166esr CC should be slightly smaller due to the difference in Vas." Ron C from fullrangedriver forum
Finally found it after restful

I'd build it to 166e specs and adjust the volume with small wooden blocs.
dave
My thought too Dave, I will start by using only two layers not three for the supra baffle and tune from there.
Thanks
Ed
hey, i'm on the east coast and am interested in the cnc A166 horn you did. i don't know if you're doing a one off or production run of flat packs but would probably get killed by shipping cost etc. sorry if i missed anything, prob. everything in your link wrt flat packs. so however i'd like to know if i could have a local shop do a one off from your cnc A166 program disc or whatever it is that they call it.Thanks Dave for the reminder 🙂

i'm trying to build a few different horns for my 166es-r drivers to find out first hand what sounds best vs., livability and waf. a cnc program would save time on one design which i may otherwise pass up. i have a dewalt 10 compound sliding miter saw, table saw so the angles aren't a problem just time consuming.
thing is, i'm not thrilled about building a speaker that has to be in corners to work properly given i've few acceptable corners to use where i'd want to keep a system. if cnc'ed i'd build it to try because of the ease. at the present a scratch build isn't very high on my to do list for the aforementioned reason and in part by ron clark's nonchalant aloof attitude toward the horn on my 166es-r thread. ron specifically said the A166 is passe and not designed or optimized for the 166es-r, not very encouraging. you're layered version with acrylic sides is visually exciting and well, were all blinded by beauty sometimes so i may want to give it a go. i don't know, we'll see and the cnc program would help with that if you can.
