Jupiter 5/4?

[bububassboner]

In a different post Roger Lewis said this...

Jupiter is going to be introducing a pro level 5/4 this month sometime. I heard about it at Midwest. Based on how their 4/4 sounds and plays it might be worth looking into. I have no personal experience with this instrument at this time.

All the best.

Does anyone have more info on this? Maybe a picture or 10?

I've seen the 5/4 jupiter. It's designed the same as the 4/4 model just with a larger bore. It's wrapped very similarly to the Besson 995, but doesn't look quite as big but they haven't settle on the size yet I don't think.

Has anybody played this Jupiter CC Tuba?

The new larger Jupiter won't be put into production. Jupiter is going to make the horn larger and fully 5/4. Similar to the Thor and equally large horns.

Any one hear anything about this horn lately?

The tuba studio at Fredonia shares tuba storage/practice rooms, so I get to play a 1291 BBb, my 188, a Jupiter 4/4, and a vintage CC 186. Fun!

My impression of the the Jupiter:
low end wasn't impressive. But, it wasn't edgy, so if you don't like low-end edge, there ya go. Above average middle range, and average high end.
I really liked the action/throw of the pistons. Great ergonomics. Intonation was excellent, I think(don't remember).
Strange 5th valve linkage. The rubber stopper would fall off sometimes.
Some of the problems could have been exacerbated from the valves being misaligned and sticky.

Hopefully the Jupiter 5/4 will have some improvements.

I had a chance to play this horn at Midwest and it is definitely - on the way. The one they had there felt like the sound hit the wall about 3/4 of the way out of the bell and it played a tad stuffy in the low register. It has potential but some work needs to be done, in my opinion, before it is market ready. It is a good design but I would like to see a slightly bigger bell and the horn was pretty heavy. I think they are on the right track, but it needs a little more development at this point. I, personally, would like to see a larger bell and more resonance out of this instrument.

Just my opinion.

5/4? Really? Looks thin in the bottom area for that....

I had the same thought, but Jupiter labels it as a 5/4, so I'll honor their opinion.

(My 188 looks bigger)

Personally.... I thought their 4/4 played more like a 7/8 tuba... (not that big for my tastes)

As far as I know, there are no ANSI or ISO standards for the "x/4 system" (see "Rudolf Meinl") ...

I've played two prototypes of this horn, one last spring and one last fall. The first one never saw the light of day but the latest incarnation is definitely in the large 4/4 to 5/4 range. It played well but still needed improvements. Jupiter was experipenting with some square slides, but I guess they've decided against that.

Not what I'd call a 5/4, especially due to the bottom bow and more tapered throat.

At the NAMM show, Sam Pilafian demonstrated a rounded tuning slide and square one in front of myself and Steve Ferguson asking for opinions of the overall change in tone quality. They're not done with the tweaking and possibly using some square slides.

I understand and greatly appreciate graduated bore as applied through a rotary valveset (around .08" from top to bottom on my Neptune). But how does one obtain a significant increase on piston valves between 1 and 4 without it looking and feeling weird? Isn't this more a matter of stepping up the bore from 4th (piston) to 5th (rotor)? What am I missing here?
