change the midrange

[greyhound]

does anyone know if the century 500 is a gold model of a different midrange.
like the 050 gold tweeter is the same as the TI 050.

if i wanted to replace this midrange wich model should i take.
i tried to get some info on this but cant find anything.

all help would be welcome.
thnx

At the very least they are cosmetically different with the gold plating. Should be the same midrange as an LSR monitor. Why would you want to change it??

there's a guy on my dutch forum that makes great modifications.
(no psycho tweak) this is for real.

but when a speaker has an alluminum voice coil it doesnt work.

so the same driver with a copper voice coil would be the answer. if this is not possible i have to sell my speakers.
i was planning to do this but i just can push myself to do so.

even an alluminium stabelizer ring gives problems.

this modification is higly debated on a dutch forum , but if you listen you cant deny it.

What does the voice coil wire being aluminum or copper have to do with the modifications??

C500 mid range is available since it a the same as it is used in LSR6332

there is a problem the basket is different

Beware Vodoooo

I'm an electrotechnical engineer. I can't see an electrical reason why the winding material should be of any problem.
Maybe it's a metalurgical reason?

Sorry to butt in where I have no dog in the race, but you all have confused me. In Greyhound's thread in which he decides he's not selling his GCs, one reply insists the mid-range is what makes that system so uniquely wonderful. So what's the problem? Allergies? :dont-know

The mid in the century gold is what make it (and the LSR32/6332) special.(and the gold tweeter is what make it expensive )

its difficult to understand. there was this dutch inventor who came up with the idea. he was working at the dutch broadcasting corporation.

he passed on his ideas to 2 people wich one of them is a guy at my forum.

he understands this technique. i understand part of it but cant tell anybody exactly what i know.
maybe in the future.

i went to his place to listen to the modifications and it was truly beautifull.
there was a dissapearance of the acoustic of the room.
music was bigger than the system and the room.
like you were there.

im not joking

[greyhound]

okay thanks a lot

but this is the same driver. so its safe to say that there's aluminium in it.
im looking for one tahts different.
realy great that you took the time for this
thnx

i cant seem to find any info on jbl midrange drivers.
but there should be a lot out there.

any links?

[greyhound]

the mid from the TI series might do the trick.
5"
but the search engine of this forum doesnt find anything.

its your century gold and you can do anything to it but don't you think your changing the hole design

What you heard in your friend house was another design different components, XO, room acoustics etc etc

do you think that just changing the mid will result in the disappearing act in your system in your room

envelopment is a very important aspect of room acoustics that has to due with lateral reflections and certain frequencies
