Passive Jubilee Crossover controller...

[Schu]

Could this unit be used to PASSIVELY control the crossover for a Jubilee 2 way system?

 

 

 

 

 

• Crossover network for the Utopia Be Focal NO6ACTIVE 2-Way Systems
• Two woofer knobs give you a choice of 10 low-pass frequency settings and 8 different crossover slopes
• The tweeter knobs let you select from 7 high-pass frequencies and 8 level selections
• In total, the Crossblock gives you 80 woofer settings and 56 tweeter settings
• Heavy-duty, hand-rolled coils and capacitors
• High efficiency and low distortion

Very nice! But I bet it ain't cheap.

Neat unit.  But you would still need to EQ.  Why not a pair of passive networks and an EQ?

And....correct me if I'm wrong...... still no driver time/phase alignment.

[babadono]

High $$$$$ ( I am assuming) crossover with electrolytic capacitors? Hmmm

I don't think that's possible in a passive.

So these would probably be better suited for a direct radiator application versus a long horn loaded LF.

Focal two way speakers likely using Be tweeters will have a much higher crossover than what is used to the typical 402 horn.

Do I recall that Roy's original crossover cost about $600 to build?  (maybe it was cost of parts or something?)

 

Looks like this one is $1,000 after a $300 savings.

Roy designed a passive for Jubilee, it is pinned and up here somewhere.  You have to live with the time alignment issue.

 

@mark1101 has experimented with this extensively and can tell you his opinion about passive vs. active with time delay, and analog vs. digital crossovers.

This is a Jube passive

[DeanG Crossovers]

Yeah, the $3000 in parts version.

--- Holy Shite ?! I thought my two board Crites passives were big, and I Know they ain't $3K ?!

[Coytee]

This might give a better perspective on size....  it's big..... really big.

--- damn. Looks like a 4x8 sheet of plywood cut in half --

It almost takes 2 to carry it, but he wanted the best.

[Coytee]

I think he hangs them on his wall as functioning art. 

 

 

[Coytee]

Yeah...one person could carry them....then you realize what might happen to you if you dropped it with nowhere to hide....

 --- Ok, I've heard about these being hung on the wall. Are they Deans or ALK ?
