I'm a bit confused.
Table Tuba has a construction Degree of Difficulty of 3, but has 9 folds in the horn.
The Tuba 18 has a Degree of Difficulty of 5, but has only 7 folds in the horn.
Can people comment on what they have found is the construction degree of difficulty of these two subs.

Currently I am leaning toward the Tuba 18 due to its boost around 60Hz.
The subs (I am building 2) will be used mainly for movies and occasionally listening to music.

Cheers

Having fitted drivers in T18s, it's a bit tricky! But it's a good question.

It's not the number of folds that makes the T18 trickier to build, it's the need for a driver chamber cover as well as the tight fit of the driver.

That's a good reason I'd certainly have to agree that, while not really difficult, having to cut the access cover and creating an air tight flange does add to the difficulty of a build. (my experience with the Tall AutoTuba anyway)

Hmm, when in doubt, read the instructions.
Sorry Bill, I didn't realise that the TT didn't have an access side cover.
I assume that's what gives the TT a boost around 30-40Hz.
The bigger opening would also make installing the driver easier.
Interesting how critical the TT's placement is too. But that will suit me.
