Tuba 18 vs Table Tuba

#1 Post by Nordo »

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 :wink:

Having fitted drivers in T18s, it's a bit tricky! But it's a good question.
Built:
6xDR200, 2xT39, 2xT48, 2xJack110, 1xOmni10.5, 1xAutotuba, 1xT18, 1xSLA Pro, 1xW8, 1xW10

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 :thumbsup: 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)
Build in process - 2 WH6, one Alpha 6a loaded, one PRV Audio 6MB250-NDY loaded

Two 2x6 shorty SLA Pro's
One T39, 16", 3012LF loaded
Tall AutoTuba, 20" wide, 2x 8" MCM 55-2421
TruckTuba, 8½" wide, 2x 8" MCM 55-2421

Hmm, when in doubt, read the instructions. :oops:
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. :wink:
