My way if mounting it.
This way the hurricane nuts line up perfectly.

I don't know if there is the space in a T60 to do it, but what I did worked quite good!

It is the first post. On that page.

How much voltage can this driver take?? (JBL GTO804) I've had it up to 20v, that gave me a headache, so I turned it down and during listening it peaks at about 2.5v If you want to play it safe, don't go beyond 25 volts or so, which is about 80% of the RMS rating of the driver (~28 volts is the RMS ...

I've now turned the Tuba 180 degrees, so the mouth is away form the corner.
Stupid move you might say.
Not in my room.

This way the bass seems so much more omni directional!
And it takes the top off of the very low end, which actually is rather loud!!
More testing to come

Sure! The panel with the hurricane nuts are the one that is being permanently installed in the Tabletuba. The on with the rubber gaskets are the one I will be screwing the driver to an then fasten that panel to the Baffle. That makes sense. Is that a new addition in the plans or is that something t...

So it is now done!
Havent pu any finishing touches on it yet, and don't know if I will be doing that either.
Too lazy to take it downstairs again when I can watch another movie

While I resize pictures and upload, all you in here with Tubas, take a listen to this track!

I thought I knew that track well, altso the bass part of it.
The deep end is astonishing

It is done

T Even more since I've seen other builds where the spacer is held in place by Hurricane nuts and bolts. In every build I've ever seen, the spacer is glued in and the nuts and bolts hold the speaker. The spacer is essentially part of the baffle, not like a giant washer that can be taken on and off. ...

This is one of the places where I misunderstood the plans.
I actually thought I was supposed to do it this way.

But we'll see either this evening or tomorrow when the glue is dry.

Well, I will try and see if it can be done.
I plan on using some rubber gasket, the same as on the wood panel, between the hard rubber gasket and the wood.
That way I should get some nice compression, without having to dig to deep in the wood.

If not then I will have a problem

Panel 9 and the braces for panel are in place. Panel 10 are in place, but not the bracers yet. A conclusion on this build so far: DON'T go with 17" wide panels. You will have to make two bracers :broke: hehe, I can't imagine the difference from 16" wide panels to 17" wide panels would...
