So, One of my rear speakers stopped working and I mailed Logitech and got the following message below that may interest some people . .

Dear Mr 'DS',

You have recently contacted Logitech’s Customer Support as your Z-5500 speaker system produces a popping sound. You expressed your wish to receive an improved version of this set by the end of June.

After sending out the first batch of optimized speakers last month, we received mixed feedback. All customers who received the new speakers found that the popping issue was reduced. For some, it has reduced the popping to an acceptable level; for others it hasn’t.

Logitech has evaluated this feedback and we have decided upon a last solution which we hope you will find more acceptable. It is not Logitech’s culture to disappoint its customers.

This means that we continue to investigate the popping issue. We suggest using the results of our investigation to hand-build a few prototype speakers which a number of customers can test in real environments susceptible to popping.

If those customers feel satisfied with the prototypes and we manage to certify them, Logitech will produce a limited number of units. However, if the prototypes prove unsatisfactory to the customers, we will not offer a short term solution and take on all the learnings from the investigation and bring them into our future products.

Although I have high hopes that we will be able to offer you a satisfactory solution, I want to be honest too and emphasize that we cannot guarantee this process will be successful. It certainly will require more patience from you – the whole process might take up to six months. Nevertheless, we think it is right to go this extra mile.

In addition, we would like to offer a further option for you to choose from, namely the opportunity to replace your speakers with Logitech’s Z5450 speakers.

This means you now have four options you can choose from:

1. you can choose to await the outcome of our investigation and accept one of the “limited edition” speakers we intend to develop, test and certify. As said, there is no guarantee this investigation will result in these speakers being developed and the process may take up to six months;

2. you can still choose to receive an optimized speaker set which we can deliver in the coming few weeks. All customers who already received such unit have noticed an improvement on the popping noise with these speakers, although some still experience noise. If you choose this option, you will not qualify for another replacement should the prototypes be developed and certified;

3. you can also choose to accept the Logitech Z5450 Digital wireless speakers. We realize these are not the Z5500, but the Z5450 speakers are closest in terms of performance and wireless. Detailed product specifications are available on www.logitech.com. If you choose this option, you will not qualify for another replacement should the prototypes be developed and certified;

4. you can request a refund. We will require (a copy of) the original purchase receipt for this.

We look forward to hearing from you which of these options you prefer to choose. Please reply to us until Friday 30.06.2006. If we do not hear from you until that time, we will presume you wish to wait for one of our “limited edition” speakers to be developed.

In closing, I apologize for the inconvenience and would like to thank you once again for your patience and understanding.

Kind regards,

Ben Gorter,
European Customer Support Manager

Interesting. I had the popping issue with my sub when I first got it (not frequent enough to annoy though), but it seemed to clear itself up after a month or so of use.
It might be pure coincidence that I got my Antec P180 case about the same time as the popping stopped, though it might be shielding my machine better making it effect the speakers less. Just a theory.
 
No i have a p180 and get the popping, the popping happens when a third device such as a cooker or light is turned on or off in the house.

I e-mauled logitech and they gave me some instructions on how to test my speakers, the tests showed they 'popped' and i have requested a refund which i have now receuved.

To be honest logitech have been very good.
 
Ive just set em up, and the center speaker makes this weird popping noise. Ive only noticed it when playing "Reptilia" by The Strokes, but ive not had time to test em out properly yet.
The noise it makes is like when you blow bubbles into a drink with a straw. Thats the best i can describe it! Is this normal? At the moment the speakers are only 12 inches from my head, so could this be the problem? (moving them soon)
 
I think the popping when devices are switched on or off at the mains voltage is quite common. My Hi-Fi amplifier does it and my old one did not. I'm not certain on it, but it might be because of the use of unearthed, double insulated transformers that is so common now. This means the metal case is not at actual ground potential, and so is more succeptable to this kind of interference.

This would fit in with my setups, with my old amplifier using a standard earthed chassis transformer and remaining relatively unaffected by RF, and my new one using an unearthed toroid and being quite heavily affected by switching on loads. The unearthed design does mean ground loops are less likely though, and often high power devices have to/are cheaper to make using toroidal transformers, which are unearthed.
