Dual Loaded lab 15 Tuba-60

#1 Post by zefrenm »

We have 6 tuba 60s and after much debate and procrastination, my cousin has requested that four of his Tuba 60s' be replaced and combined into 2 cabinets. He has also been sold on using the correct inside widths this time too. A tuba 60 with an Internal width of 24" is convenient but stifles the bass. He is sure of it after hearing the tuba 24 built at recommended width, and he feels that the added width will be worth it. My plan is to build two T-60s together with them sharing the center panel since getting a 60"x 54" is impractical, as are gluing boards together. The build will be off an on as we are preparing for Electric Daisy Carnival and my sudden weight gain has necessitated the need to cut and tailor a new wardrobe.

the center panel acts as brace so weight can be cut here. Following the lines from the tuba 24, Victor Horta Art Nouveau-ish.

Not sure if I understand. Are you building 1 huge cab that is actually TWO T60s together, sharing "a side", in this case the center panel? Being that the inner panels have to be placed in the exact same spots, I would think securing the inner panels to the common center panel would be problematic.

Why not just two separate cabs, or one monster dual-12 cab?

Looking forward to the build. Good luck.

I'm confused as to why, normally you build duals just to save wood and build effort, it would make more sense to just build 2 cabs the way you are doing it. you just need one more side then! please explain
Before Fitzmaurice, big bass could only be had with just a hook and a nightcrawler.

maybe they operate a large tour based company. in this regard, less boxes equals less staff needed/less time for setup (only have to haul half as many boxes), as long as you've got a forklift.

also, now they can easily wire it for series lol.

Days 3 & 4

After coming back from Electric Daisy Carival, ive been busy with 3D renderings for an upcoming show and have been stifled by the heat in the garage. Over the past few weeks its been 110 degrees in the evenings in there so i havent wanted to build. But i did score some fans so as long as i profusely sweat im fine.

This panel is the most crucial in terms of accuracy, placement and alignment. a few 16ths off here is a world of woes later. Thank the lord for Compass and rule.

I love this way of building the tuba. two sets of guide lines, no straining to make angles meet or fancy straps and clamps.

Zefren, this dual T60 build of yours makes me wonder if you ever considered bolting some barndoors a la "Levan" to 4 of your T60's to increase the mouthsize even more... :noob:

Epic build, keep on making sawdust!

Looking great.

For some reason, you strike me as the kind of person who is just going to keep on building T60s until you have enough to sink a ship!

ZEF you are like "The Mad Scientist" of Tuba 60's 8)

So many different and interesting ideas, the concept of having an 'artistically' perforated central panel in quite possibly the largest Tuba 60 ever just has me in awe - the concept is one thing but harnessing the ability to do it without hundreds of dollars worth of fancy power tools is sheer brilliance.

I'm so pumped to watch this build progress through to completion, I sincerely hope you pull it off flawlessly without any major mishaps.

One question; Installing the panels for the horn path, with both sides already in place - how do you maintain sufficient glue within the joint whilst sliding the panels into place?

Absolutely sterling efforts my good man :clap:
