Were I in the market for a legit monster-sized horn and didn't mind BBb tuba this would definitely get very strong consideration from me.

That's not true. Rudi Meinl made much more of only 3 6/4 BBb. I have seen defently more than 3 here in Europe

Maybe Dave meant that there are only 3 made that are in the US.

I've played the one that is now at Baltimore Brass. It is huge, but it's much easier to play than you might expect. It's a different blow because of its size, and it would take a bit to get acclimated, but I didn't get the "massive air hog" thing (but then again, I like big bore tubas and don't ever get the "air hog" thing). I would have liked to spend more time with it. I'd like to compare it to a Miraphone 98 and 497. And a MW 197. And I'd like to have the dough to be able to travel and test them all.

This is purely a question based on nothing but speculation. Is there a difference between a Rudy 5/4 BBb and the 6/4 here? I would assume there are many 5/4 BBb Rudy's, but given the size of their 5/4, I would think a 6/4 would be very rare.

There is. The 6/4 has a 22" bell while the 5/4 has a 20" bell. I'd assume the 6/4 is fatter too. The Rudolf Meinl website says the 5/4 is wonderful for large symphony orchestras, while the 6/4 is preferred in large orchestras for Wagner. Not sure what the difference between that is, but it seems to be more than the bell size. I don't really know either, though.

Imagine spending $22k JUST to play Wagner with it. Oof!

I owned a Rudy 3/4 CC for many years (should have NEVER sold it). When I bought it, I didn't know it was a 3/4 tuba, and it certainly didn't sound like one.

For technical clarification and unnecessary minutiae...

BAT = Big Ass Tuba (or Big Assed Tuba) - a term (coined by Tony Clements?) referring to really big piston valve tubas

BART = Big Ass Rotary Tubas - refers to really big rotary valve tubas

My understanding is that a ban (along with Emmett's works) has been in effect.

1) Did you actually play it?
2) Did you play it with the same mouthpiece you use on other tubas?
3) Did you try to overblow the horn by subconscious reflex or conscious thought, "It's a bigger horn, it must take more air...."

From my experience, playing many different instruments, including a Conn 38K which due to the size of the bugle taper is arguably a 6/4 horn, a large horn cannot in and of itself take more air than a 4/4 sized horn, whatever that may be, for two reasons:

1) throat or venturi of the mouthpiece;
2) the purpose of the mouthpiece being the transition of flow theory over the embouchure to static wave theory resonating the given pitch.

No matter how large the expansion of the bugle, a person can only get so much air through a mouthpiece with a given venturi. This is a matter of physics, flow rate, and Bernoulli's principal. It may seem like it takes more, but that is usually the function of a turn in the tubing or the placement of a brace interfering with a node or antinode, the response of one or more notes, and the player pushes harder to get the same response.

Example: I used to own a Besson BBb New Standard 3-valve comp. It played great. Second ledger line CC below the staff was stuffy, and I found the place that caused it. But it was in the valve block and I couldn't, of course, change it, as I could have if it were a brace elsewhere on the horn. So I had to be careful to not push the CC any more than necessary. Likewise, I had two mouthpieces: the Wick 1 with its 8.4 mm throat, and my custom Kanstul 18 with the same cup diameter, but an 8.2 throat. Yes, the funnel cup of the Wick 1 versus the bowl cup of the 18 also figured a little bit into this. The Wick 1 was an air hog because of its larger throat, and a lesser extent the funnel. The Kanstul 18 I could play all day and support any phrasing. Likewise when I played a PT82 on a Conn 38K: basement to above the staff all day long, no breath issues as it also had the 8.2mm throat.

Larger tubas do NOT take more air. Because of the extra mass, they do need more efficient air to get the most out of them, which entails fitting the proper mouthpiece to both the horn and the player to manage the breath support, especially in cup size and geometry, and most importantly, the throat and backbore geometry.
