Hi there: No, there are many possible designs presented. Take time to read the whole thread to gain some understanding of Tom Danley's wonderful tapped horn concept and the DIY possibilities including many comments by the inventor TD and others who have constructed TH(s) . ...regards, Michael
No colaborative design needed. Just download hornresp, google for the awesome tutorial which one of the member here did on another forum (google for "tapped horn tutorial") and put in a driver you like. If you dont know which driver, try some pro audio ones, they usually all work great.
Or just use one of those: http://www.volvotreter.de/th.htm

I´m sorry too post this, but I just dont bother reading 350 pages of replies
Have you all agreed on a collaborative design?
Here are some of the completed projects photos

Would these principles hold true for TH and T-TQWT as well?
Port Flares - Evaluation of noise
Port Flares - Evaluation of noise
Can anyone tell me how to determine the Rms value? Its the one I always have trouble with and can never find it.

Large Scale signal analysis ( like Klippel ) is not part of evaluations.

Neither are the thermal effects.
These are important considerations.
On more than one occasion the same horn designs loaded with Eminence drivers failed compared to the same design with JBL 2226H drivers after periods of extended hard use.
( I would attribute this to JBL's more robust design and the superiority of the SVC cooling system that dissipates heat more effectively. )

Does this comment pertain to one of the tapped horn projects in this thread? If yes, which one. Is this part of your personal experiences? If yes, can you expand, e.g.: time, place, event.
Thank you for the Klippel poster, and any additional information will be appreciated.
Regards,

It was a folded horn ( but not one particular to this TH thread ).
It was a design used for exclusively for PA on another forum.
The situation was 8 cabs ( 4 with 3015LF, 4 with 2226H ).
After 7 hours of use the 3015 were dead.
The Loudspeaker handbook By John Eargle
has Chapter 9 "Thermal Failure Modes of Loudspeakers"
page 233 - 243 ( use Google Book preview).
It details and graphs the VGC system
( which I incorrectly called the SVC system on the previous post )
Syd
FWIW: I can attest to the durability of the 2226H.
I measured one that was part of a large touring system with 8 years of hard constant use and the T/S parms. were very close to manufacturer's spec.

I had to reduce the bass speakers to well below 1W to get the total sound from the stereo pair of full range speakers and the mono bass speaker to sound right.
Listening to just the bass speaker there seemed to be very little information.
Listening to just the small full range speakers gave an acceptable sound.
Adding the bass channel and the sound became real. Turning off the bass channel and the music lost and voices lost that "realness".
The mains were running at ~0.5W each and the bass ~0.1W
Although the bass speaker is twin 18inches it is not a sub woofer. Output falls steeply below 20Hz.
