replacing a woofer in JBL L890

[wvtrumpet]

Hi guys,

Newbie here. I just recently purchased (last week) a pair of JBL L890's. Anyway, they arrived and I was very unimpressed with the sound. Come to find out that one of the woofers is bad. JBL is sending me a replacement. How difficult is it to swap the woofer? I really have no idea how to do this. I was also a little upset with their customer service. I was sent to seven or eight people before I got someone that could help me. Thanks everyone. Looking forward to responses.


Thank you , Neil

You did pretty good by getting a fresh woof sent to you, here's hoping that's going to fix it. While you're waiting you could try swapping 2 woofers around to see if a different one works in that hole. Be sure to keep the wiring color scheme correct.

All you need is the correct tool for the screws holding it in, takes about 5 min to replace one.

Thank you, I will try that tonight when I get home. Score one for the little guy I guess

As I recall, those use the star-headed furniture screws.

I was able to take out the woofer tonight. It was a very easy job. I did not try one of the others, but will. Amazing to me how badly one bad speaker was making the whole cabinet sound.

Which is why I was curious about whether the woofer is really the problem. A bad crossover could cause the same symptoms. Swapping in a different driver will rule that out.
