While interference on the rear speakers wasn’t an issue, it certainly had one major side affect. I run a Wi-Fi connection in the same room and was used to being able to stream video content over the network to my Media Center PC under the TV. However, with the speakers on this proved impossible. The battle for the 2.4GHz frequency band severely reduced Wi-Fi speeds. The wireless adaptor on my PC dropped from a full 54Mbps signal to a only 1 or 2Mbps every time the speakers were on. While this was enough for regular web browsing it completely knocked video streaming and wireless file transfers on the heard. Turning the speakers off and all returned to normal. It was a black and white, on/off situation.
That aside the Logitech Z-5450 are hugely impressive, especially when one takes the price into account - you can pick them up online for a little over £200. At that kind of price and considering the quality and convenience, these are an absolute bargain.
As long as you don’t have to have maximum Wi-Fi bandwidth while the speakers are on, these could be the speakers that bring surround sound into a great many homes, and for that Logitech ought to be applauded.
Inevitably, purists will turn their noses up, but if you’re a person that has to deal with the WAF (Wife Acceptance Factor) or just don’t have the time or patience to faff around with ripping the carpet up then these are just the ticket.
Thanks to rear speakers that only require power and receive their signal wirelessly Logitech has produced a set of surround sound speakers that have a vastly increased chance of gaining the WAF (Wife Acceptance Factor). The drawback is that due to signal contention Wi-Fi bandwidth is drastically reduced when the speakers are on, which will prevent video streaming. Unless that’s a deal breaker, this set comes highly recommended.
