Dear Rob,
Really Thankful for the detailed description for the Speaker Repair.
It really helped me a lot. I have a unusual situation here with me. I have dissected the whole console and found the outer band of the speaker has just come off....have attached photos to make it clear. does the outer speaker cone will make a difference or i will have to replace the speakers itself.....when i checked pressing the speaker down and played the distortion had gone....but while playing without holding the distortion would come back....Hope you can help me in this situation....Thanks in Advance..... 
Well Problem solved.....The foaming had gone bad and brittle.... changed the foam of both the speakers and yohoo its back to groove.....thanks for the help......
Hi , thanks for this topic, i would like to ask how do you remove the front grill? Thanks!
I read elsewhere that it is possible to pry off the grilles, and I tried but failed multiple times using different methods, so in the end I just PUSHED them out, from the inside using the blunt end of a rod carefully poking THROUGH the already broken foam surround which I was replacing. Functionally a success, but the convex surface of the grilles are not mint-condition anymore.

The carton (speaker cone) can come loose from the rubber band that should hold it firmly in place. They are supposed to be glued together. This is what I did. I removed the protecting grill in front. Check if the cone is still connected to the rubber band. If not, I remove the screws around the speaker. Open the casing itself. Do not forget the screw in the middle of the battery compartment. Remove the bottom cover. Disconnect the 2 wires on the speaker and take out the speaker. It will come out with the plastic protection around it. Looking at the cone now, push up the Carton cone and keep it in place by putting some tissue paper or small cloth underneath. Clean the cone first. Use some rubber cement on the outer edges of the cone and press the rubber back on the cone. Let it dry for an hour and then remove the tissue / cloth, so the cone goes back to its normal position.You can use some extra rubber (those pre-glued strips that you would use to fix a bicycle tire) to make it extra strong. Remount everything back in place and voila....it works again!If your cone is not damaged, the casing most probably does not seal good anymore. Tighten all screws a little more and use plastic electrical tape all around to seal all joints. The bass is produced inside the casing itself and pushed out via a horn. If it is not closed off well, your bass sounds grumpy.Good luck.Also check: http://www.youtube.com/watch?v=CtuDJCqGb6I
Dear Nishant, you cannot order these "Atlas" drivers/speakers from Harman Kardon. See here their response: "Again, as stated many times, they are not for sale. We do not stock them separately. They cannot be purchased. Best Regards, Vu Le Technical Support Specialist III Harman International Lifestyle Division 8500 Balboa Boulevard Northridge, CA 91329" Basically, we are srewed. I tried to put in another driver from another brand, but the sound is horrible. Especially since it is almost impossible to install another driver as such that it fits tight. If it doe not close of all gaps, the soundbox will not produce any bass. In the end, I just stopeed finding solutions and bought myself another system. Harman Kardon sucks because they offer no service at all. Oh no, not fully right, they offerde me 205 discount on my next buy, but then you have to live in the USA !
