Cal,
the driver chamber throat CSA is about 130 cm sq, the volume at 4 in deep is 3900 cm cube, thus the upper cutoff freq given by fh = c x Athroat / (2 pi x Vchamber) = 180 Hz. Perfect for bass enhancement from horn. 4 inches is good number.

Yep. that's more or less the dims. I came up with an NS6. Too big for my purpose. I can reach similar low freq. (39 Hz) with the 5" Visaton in a much smaller enclosure. Let me think about it, and see if it would work as a compliment to a pair of full range on-wall Cornu-Spiral.
Why would a 5 in Visaton reach 39 hz easier than 6 in Aura ns6 in smaller enclosure? Lower fs?
Thanks. I have to keep them close to me or they might slip under the radar. I really do owe them some of my time.
I will need a tweeter with the CSS mid bass drivers so the OEM polycarbonate domes, Technics paper cones, Hi-Vi SS1-II fabric domes and the CSS RT1 ribbons all followed me home today.
I have a feeling the ribbon motors will take up too much space inside but I am hoping to find a nice match with one of the other three, something I can fit fairly close to the woofers.
Just thinking out loud for now as that part is still days away. 🙂
Cheers.

Not much lower fs, but still lower at 52 Hz vs. 55 Hz for the Aura. There are other considerations. Here are the specs.
God! I hate it when inanimate objects do that! I always have a difficult time explaining that "Twilight Zone Effect" to my wife...😀
Yes but it means moving it further from the bass unit
416-8C
Mine stopped asking a long time ago. 😀 Thankfully these are not recent purchases, just stuff othwerwise collecting dust.
EDIT: I was in a rush. If the HiVi dome sounds best [I use that tweeter for the livingroom TV] I will use it. I will simulate where the tweeter can actually be placed before the final decision is made. I hate to admit it though, I am still a sucker for a good paper cone tweeter. Call me old fashioned but if the Technics happens to win, I won't beat myself up over it, and I do have others I can bring to the table to make sure I'm not being an sentimental idiot. 🙂
Hey Big Al,
I think you are right. I will if I can. I begin the cabinets soon I'll be able to tell more in a few days.

Nope no room for a ribbon unless I move it out of the driver chamber and that means too much separation between them.
Note to self: Just because you Googled "Perfect Pentagon" doesn't mean that's what will show up on the screen. Should have checked, would have saved time on layout. 😡
Tonight I start the channels. Pics coming soon.

So the interesting part has begun. I am making a big mess and it is going very slowly.
Cutting the channel pieces with a bandsaw works really well but everything else makes me want to cut off my...
This better sound good 'cause this is way less fun to build.
Next time I have a bright idea can someone just smack me up side 'o' the head.

No need to smack you, usually when one gets this kind of ideas there is no stopping anyone. Waiting for the end result. So, less posting more fabricating...😀 You can post everything when done.
Maybe that's the smack I need.
Back at 'er tomorrow, there's a hockey game to be watched tonight. 🙂

Wow, you are taking foam fabrication to the edge. Even if it does not sound as good as the effort applied, you have pioneered a new technique in enclosure materials and construction.
Can't wait to hear the results.
