Question about Quad 11L Main / Stereo Speaker

Re: Quad 11L tweeter replacement

Thanks for your help!

So what tool would you use to wedge out the woofer without damaging the lacquer coating and the rubber around the drivers?

Is a knife too tough?

Should I deliver it to a service centre? Only unauthorized ones are available where I am (in Dubai). The cost of labour is approx $80.

Given the relatively small cost of the repair, I'd have the servicer do it. That way if anything happens, he/she is respionsible for it. When I repair this type of speaker, I usually use an old chisel. It is sharp enough to get under the edge and strong enough to pry up the speaker. Just be careful not to nick the cabinet.

    I found a more low-tech solution, removing the allen screws first from the woofer, placing the speaker on its side and using my fingernails to gently prise out the woofer. Once the woofer is out, I removed the tweeter screws and put my fingers into the hole and genty pressed the back of the tweeter. If your fingernails are too short, you could grow them, or perhaps you know someone with longer nails.

I open my b212a and disconnected the speaker and horn wires and know i have completed my repair i am read to reconnect and i don't remember which set of wires are the positive side


Because the system is bi-amplified, it is important to replace the wires correctly to avoid phase problems. I don't know how the wires are colour coded, but if it is any help I downloaded the schematic and the wires are numbered 1: Woofer Active 2: Woofer Earth
3: Tweeter Earth and 4: Tweeter Active. Sorry if that's no help. Otherwise it should be easy to trace the wires to see which connect to earth.

Yes the woofer and tweeter can be replaced but the woofer needs a recone kit to repair as the whole speaker cannot be replaced without replacing half of the speaker enclosure.... call JBL pro or a service center for help.

My Bose l1 tweeter cuts out. any suggestions?


you are most likely turning it up too high so it cuts out to protect the speaker. Get bigger speakers.

JBL speaker's woofer occasionally cuts out - tweeter still works.


Your driver has a damaged voice coil, you can either find a speaker repairer to replace the voice coil or find a replacement driver to fit.

Quad 11L distorts sound temporarily at the beginning of a session


Swap the speaker that makes the noise with one of the others. If it acts up on the new channel you know that it's got a fault on it. However if the noise appears on the new speaker the fault is in the amp (perhaps an overheating transitor).
Looking at the picture on fixya of the speakers, it seems unlikely that the speaker units would cause that fault, but the crossover could in it.

Woofer doesn't work


sounds like the voice coil could be open or damaged. the woofer can be reconed. reconing replaces all the moving parts in the speaker frame returning to new condition in most cases.

Need to replace 11L tweeter


the best solution I've found is this:
1. Remove all the tweeter screws.
2. Take a thing metal rod (a coat hanger should work) and lightly tap the tweeter through the top port in the rear until it is loosened and comes out. The tweeter is totally sealed so you probably won't damage it if you need to do this to a working tweeter.

This method also works for the woofer but you need to be very careful to tap the frame or magnet of the woofer and not the cone.
