Logitech’s Z-5450 digital speakers (see the figure) are wireless. At least when it comes to the rear speakers. This greatly simplifies placement and reduces wiring clutter.
Reducing clutter is only part of the Z-5450 story. It delivers up to 315 W RMS to the speakers with a peak power of up to 630 W. There are 5 satellite speakers with advanced aluminum phase plug drivers that are enhanced by a digital equalizer and a heavy-duty, dual-chamber subwoofer.
The Digital SoundTouch Control Center ties it all together. It decodes Dolby Pro Logic II Surround Sound, DTS, and THX recordings and transmits audio streams to the wireless rear speakers. Redundant wireless channels prevents loss of sound when interference from other radio sources occur. It uses 38 channels in the 2.4-GHz band. Latency is less than 20 ms. It also has multiple digital and analog inputs. It works with the wireless remote that can select up to 7 audio inputs. The Control Center has controls for volume and effects settings. The system can synthesize 5.1 surround-sound from stereo inputs. The Control Center has headphone and audio out connections on the left side. The system comes with all wired cables. You will need to provide your own coax or fiber optic cables if you use those inputs connectors.
The sound quality is simply excellent when combined with a good source like the audio system on the ASUS motherboard. Highs are crystal clear even during very quiet passages of a symphony and when the bass hits the gut while playing video games. It was a joy to listen to movies.
Setup was much easier than 5.1 wired systems I have used. It is usually easy to run wires for the speakers next to the PC, but it was always a pain to handle the rear speakers. Logitech came up with a neat compromise with this combination.
