Not sure what TL parameters are.
Download WinISD (free) and play with it.
If you believe WinISD, there is nothing to be gained by changing the vent size from 4" to 5"
My enclosure net size is 10,702.1 cubic inches and if using the insulation boosts it by 20%, it is...
Could be I am doing something wrong operating the software also.
It would be interesting to have an original 2235 to measure as reference.
On the enclosure front, I am at 10,702 cu in (6.2 cu...
My first 2225H is done being conditioned and I did a DATS test on it again.
This is after 24hrs at 20hz and 24hrs at 32hz
This is what the software had to say...

I'd like a book that I can learn in to, but is something I can understand now.
Usually I have to open the book and read a page.
I tried a few used places and of course ebay and all those that I could find are even more expensive than the new ones off Amazon?
I did see that the library in Las Cruces has a copy so maybe I can...
Meanwhile.....
While I'm building on the cabinets, I have one of the speakers being "conditioned".

What an expensive book.
I thought of buying it for reference, but they want a ton of money for it.
Does this include one diameter minimum from the top or bottom?
Very nice looking.
Do you have cad-cam software?
I was expecting different calculations other than a cylinder since it's hollow.
Easy enough.
Interesting reading.
Thank you
I think it's extremely interesting that volume can be gained with insulation.
If there is a formula or way to estimate this, I'd love to include it in my little spreadsheet.
Thanks again
Thank you for your time and effort Ian Mackenzie.
I was worrying about making stupid arithmetic errors, so this morning I did a simple spread sheet.
There are several variables like internal...
Ok
Down to 6.145 cu ft
no other drivers in the boxes.
if I use 2x2s that would be another 279 cu in.
No idea how to figure port displacement.
We're down to 6.1915 cu ft not counting the ports.
0.2 cu ft for the spkr and 279 cu in for the corner bracing.
After doing some subtracting I came up with 6.3529 cu ft. net
I'm remembering now a conversation with the speaker reconing guy (because I couldn't find any 2235s that were not crazy expensive) where he told me about reconing the 2225s with 2235 kits saying what...
The cu ft box measurement is gross, not subtracting 1x1" corner bracing or the speaker itself. The box is 30" tall, 17" wide 22.75" deep inside.
I'll be pushing the speakers with a McIntosh MC275 so...
I used the DATS V3 to drive the woofer overnight at about 30hz. So it ran from 14:30 yesterday until about 09:00 this morning. Ran the test again and nothing had changed.
Did you know about the...
Probably because it's a 2225H not a 2235H.
I just discovered that my memory was playing tricks on me.
:o:
It's different but in a good direction.
