One of my speakers only works if I apply pressure on the face of the speaker above the tweater. I want to open them so that i can look at the connections but they have no screws. How can i open these? Thank you for your help on this matter.
I have the same problem and you and Nec9.
I also tried to open the satellite and fix the speaker. You should note however, the 2.5 inch driver (speaker) is shielded and the fact the speaker only works with pressure applied suggests the problem is inside that sealed speaker. There isn't much you can do.
I've looked everywhere for an equivalent Tangband speaker (similar to the one logitech use) but I'm none the wiser.
I don't think logitech offer parts either, which environmentally isn't very good.
I had this problem as well, I finally figured out that the rubber plugs that allow you to remove the dust cover are able to be pulled off. Get a pair of plyers and just yank em out, which will reveal 4 discreetly placed screws :). I am having the exact same problem you are however, and opening the speakers up did no good for me, the wiring seemed fine but I still get a rattling or complete silence whenever I exceed a certain volume which I can only temporarily fix by applying pressure on the speaker. Let me know if you manage to find anything out and if you solve the problem, I'd like to try it so I don't have to try to find a replacement satellite.

the transformer is fine its the amplifer probably has dried up electrolytic capacitors usually a speaker has one capacitor to rework the audio levels and emphasis for the tweater
it wont be the transformer/speaker for sure
and for sure its the amp
try another amplifier or replace your ones capacitors
Place clean thicky cloth on level surface, open lid, at rear. Facia gentle apply lifting pressure to rear facia either end, held in by small plastic lugs, so be careful when applying lift, should pop out exposing speakers. Rest common sense and apply no undue pressure.
Sorry about the late response. These units are sealed at the factory and opening them up for the first time is a bit of work. Make sure that all the screws are out of the unit and using a large screwdriver, carefully pry up one side. It will be difficult. Apply steady pressure and the back will eventually free up.
Make sure the speaker select switch is on "A or B or AB. It's a small button on the front panel of the receiver (pen sized) and will give you visual feedback on the LCD display. If they are on, you need to have the unit bench tested at an audio shop and possibly repaired. Hope this helps
it is an easy fix if you know how to soder all you need is to open the side to get to the broken speaker the wire that goes connected to the speaker fell of just soder it back to the speaker and it will work
The tweater on my Q55.2 blew as well. I went into a shop in NYC and they tried to charge me $225 for a new tweater, so I took it home and called up Kef. They sent me out a new tweater for $35 and instructions on how to solder it in.
It took all of 10 mins to replace and they are working fine. I've never soldered anything before and it was simple.
The crossover wires have absolutely nothing to do with your cd player, all you do is wire your crossovers into the speaker slots on the amp and then wire your mid-range speakers and tweaters into the crossovers. All a crossover does is it splits the power from the amp to your mid-range speakers and your tweaters.
