There's a guy who is selling his jbl's century gold speakers. I am planning to buy them (i cant wait to go back to the jbl sound) but the guy tells me there are no batteries that power the filter. I tought that the century gold has a 9 volt battery in the back that should be replaced everey 2 years or so.
Am i wrong?
Is there another line of century's that comes without battery.
Im going to buy them tomorow so any fast answer could help.
For all i know its like a dummy or something.

The centurys will be my speaker for the time i will need to build my own JBL's but i heard it sounds fine
greetings from the netherlands

Well, hopefully he hasn't been running them with dead batteries for years, but who knows? Once fresh batteries are in place, they will sing as intended.

probably he has never unscrewed the back of the crossover

the battery is hidden behind a cap

good luck

Bias the caps for the charge coupled (crossover) networks

Look up the 250ti speakers (among others) and read some of Giskard's comments on cc networks

i could explain what the b atteries do in dutch , but lets just say they sound better.
lineair radiance ? does this make any sence?

I think it wouldnt be hard to find the batteries. They should be right above the terminals.
The guy is going to check it out and will e mail me if he really cant find them.
So if he says there's nothing wil i get in my (german) car and drive 2 hours to see if there really is nothing.. i dint think so. But what if the guy just isnt smart and i pass on a pair of nice speakers because im to lazy to drive
what to do, what to do.
anyway thanks for the info guys

If they truly are Century Gold's I would recommend getting them so you can experience them first hand.
You can always sell them if you don't like them.

they look the real deal, or someone put in enormous effort to make a clone. I always heard they sound really good so i think ill take my chance's and drive for a while. In holland 2 hours away is a lot for you guys its probably right next door.

Do you have to unscrew the terminal to find it?

i have tried it but the drawing is al little to small a real picture might do the trick.
Ore some one who can tell me that its a little bit hidden and an untrained eye could mis it.

I just cant figure out why someone would own an expensive pair of speakers and not know there a battrey inside.

??It's hidden under a cover plate that you have to remove. You can see that in the manual. Even tells you the sequence on how to do it.

G.T. also did a floor standing version which never made it to Production.

One thing about WAF - if the loudspeakers sound really good women grant extra leeway.

thanks that was very interesting.
I was able to expirience this effect at first hand. The moment the batteries were placed they sounded less tight then 3 days later. Everything seems more balanced now and i think they have reached there peak.
first day there was some moving around by the individual instruments now there's great pin pointing.
It seems the effect of the charged capacitators has more influence in the higher and mid range of the audible spectrum than in the lower regions.
