Tim Stinson here. Owner of Luminous Audio. Just hoping to share ideas and perhaps obtain some knowledge from others on designs repairs.
Yes. I have had many TLs, and have drawn way more — mostly Woden lines.
My first experince was a set of Radford S-90. I was also a player in the initial introduction of proprt TOL modelers — was present for Augspurger’s AES presentaion of nhis work and at the same time wa helping Martin to first publish his work on the internet. Came to this forum almost 2 and a half decades ago to clear up some TL misconceptions.

Cool. I will check it out soon. I would love to run down my design w you at some point. I am using a scan speak
26W/4534G in almost 6 feet of line. the area immediately behind the driver is 1.25 times the sd of the driver. the mouth is exactly the sd. I am using acousta-stuff throughout. A little bit of egg crate foam in the first 25% of the line. The final 25% of the line I stuff more heavily to make the driver think it is in a longer line (Albert trick). That is done to ear. Your thoughts on my basics?

To start you off (open a thread in the appropriae forum to take it further):
First thing: Sd has next to nothing with the design of a TL. And line length depends on the line taper & any mass-loading.
Soundd like a design usng "Classical Techniques{, maybe a 1 in 10 chance of getting something good, even less that it is optimal. Ibuilt a lot of those.

Hi Dave, So sorry for the delay in getting back to you sir. I and my entire family have been trading colds back and forth. Would you be willing to help me improve upon my design with the given enclosure? For a fee of course. I would love to make them better obviously. I would value your input greatly. My best, Tim
Me help design a TL? I just draw other people’s lines.
I do have solid theoretical understanding, and a bunch of experience buiding them.

Would you be willing to look at what I am doing now and offer suggestions for the same sized box?
So sorry to get back to you so late Dave. My Mom is not at all well. My cabinet dimensions are 12.5" wide, 31.5" tall and 18" deep. All walls are 1.5" thick. The mouth currently is 9.5" wide and 5.25" tall. 10" scan speaker woof. I would simply love and appreciate your help! Tim@luminousaudio.com 804-467-7900
Scanspeak Discovery 26W/4534G
12.5" wide, 31.5" tall and 18" deep. All walls are 1.5" thick
So 24.1 x 72.4 x 38.1 > 1:3:1.58
66.5 litres less bracing.
The mouth?

Hi Dave, I do not understand the......So 24.1 x 72.4 x 38.1 > 1:3:1.58
the sub's external dimensions are what I gave. All 6 walls are 1.5" thick. The vent/opening of the t-line I call the mouth as that is what Albert called it. The bracing is 3/4" a grade plywood. What else can I get you sir?

What does it looknlike on the inside?
All we can tell from what we know so faris that the box is probably small and the terminus too large.
