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
