There's an issue with the DNS servers hosting the my site's domain. I'm looking into it at the moment.
Hello again!
I tried with Google and Cloudflare DNS
C:\Windows\System32>nslookup diysubwoofers.org 8.8.8.8
Server: dns.google
Address: 8.8.8.8
*** dns.google can't find diysubwoofers.org: Server failed
C:\Windows\System32>nslookup diysubwoofers.org 1.1.1.1
Server: one.one.one.one
Address: 1.1.1.1
*** one.one.one.one can't find diysubwoofers.org: Server failed
Server: dns.google
Address: 8.8.8.8
*** dns.google can't find diysubwoofers.org: Server failed
C:\Windows\System32>nslookup diysubwoofers.org 1.1.1.1
Server: one.one.one.one
Address: 1.1.1.1
*** one.one.one.one can't find diysubwoofers.org: Server failed
and with online checkers, but maybe it will need some time to refresh the info.
Using domain server:

Hornresp seems to produce slightly different results, based on which model you use. I don't know which is the more accurate one, but I'd speculate it's the TH model.
Compare a straight flare tapped horn to a series tuned 6th order bandpass enclosure with the same volumes and tuning to find out.
Brian , how about a spreadsheet for

Looks like I can create a spreadsheet for it relatively quickly. However, what's the value of such an alignment? The box size is the same as a vented box for the same driver, so efficiency at low frequencies will be similar, and the arrangement looks like it's going to produce aberrations in the passband due to harmonic resonances. The Hornresp model also doesn't appear to be accurate as it could be (it should be modeled as a no-chamber OD design in Horresp, IMO).
I don't have a slight idea, it's sure look similar to mltl (one of my favorite alignments) you had. I am planning for a 10". Thanks
What about export (ph1)? Does that mean with the woofer flipped the other way?
Which of the BOXPLAN workbooks are you referring to? There are a few that provide the opportunity to model a specific enclosure two or more different ways in Hornresp.
Using the parac box plan I get a frequency response of 25hz to 75hz when exporting bp and I get
I know what the goal should be that has nothing to do with the question at hand.
We were discussing how there are 2 different results in hornresp when modeling but they are coming from the same box plan. Me personally for this build I’m really trying to get down to 20hz up to 70 but I’ll likely end up settling for 22 or 23 hz up to 65 in order to keep it musical.
