TH vs MLTL - AE18H+

Has anyone experience with tapped horns and transmission lines?
is there any reason why the sound quality of a TH should supersede that of the TL? The Tapped horn design in the pictures is just an example...though I haven't been able to improve upon this design, has no bearing on whether or it is possible to achieve, with a more knowledgeable designer.

Any thoughts?


(not going to change drivers fyi)

I don't really have anyone to guide through the tapped horn experience
I'm just a guy twisiting numbers to try get a response, so take the designs with a grain of salt. I'm sure someone else can do better.....actually be my guess...lol

Box has to 32" wide and about the same in dept.

If you got the space and you want a very high sound quality from your drivers.

Martinsson's Blog - ROAR18

See the original ROAR18 as an example for layout and design.
The simulation below is a larger version more optimized for your driver and a slightly lower downward response.

The plane loading of the front resonator and the splith path loading of the driver increases the ability to create very steep shock waves and enables a very high resolution of all the real life textures, timbre and modulations of the bass.

This is response that I got from the MLTL that I like, the peak at the knee is only 1db (94db to 93db back to 94db) ...91db at 20hz...1 watt...I'm trying to create the best TH to maintain that extension and a decent sensitivity

Should I be so in love with the Tapped horn as a subwoofer enclosure that I abandon my MLTL and potentially loose sensitivity for what what TH has to offer in the bandwidth that I desire? Does that question make sense?

I feel like the TH provides awesome assistance to the woofer diaphragm, which I might need in my case with my 18" wind sail but most of the levels in intended use are at 1-2mm of xmax in either enclosure.
