Performance and verdict

By Danny Phillips



Our Score:


After rigging up a Blu-ray deck to the coaxial digital input, we popped Avatar in the disc tray and settled back. Flipping to the movie’s best test scenes (Battle for Pandora and Assault on Home Tree) the first thing that jumps out is how remarkably beefy the Z906’s sound is. It gives real body and depth to the frequent missile explosions and rat-tat-tat of machine gun fire, evoking a sense of power and aggression that makes us completely understand why THX gave it the thumbs up.

There also a reasonable amount of detail poking through the bangs and crashes, and some lovely high-frequency work that gives the sound a crisp, perky feel that’s certainly streets ahead of what you’d get from flatpanel TV speakers – a fact that in itself will be enough to persuade some people. This decent detail reproduction is also noticeable during quiet scenes, particularly Jake’s regular expeditions through the Pandoran forest. Listen closely and you can make out distant animal cries, gentle ambience and the rustling of leaves underfoot. It doesn’t tease out this information with the quite the same level of effortlessness and absolute clarity as dedicated home cinema speakers from the likes of Teufel, KEF or Tannoy but it’s a good effort.

Logitech Z906 Speaker

Bass performance is excellent. The sub keeps low frequencies sounding tight and accurate, putting real punch and drive behind effects, plus it can muster a deep, sustained rumble without drowning out the other speakers. We’re also pleased with the clarity of dialogue which shoots through the busiest of scenes without any muddiness or excessive sibilance. It’s likely that you’ll regularly use this system to play music too, particularly if ifs rigged up to your PC, and if so you can expect a clean, dynamic reproduction of your tracks, anchored by nimble, rhythmic bass notes. Vocals enjoy surprising richness and high-frequencies aren’t thin.


Whether you’re using the Z906 in the office or living room, it delivers a very impressive sound with depth, punch and decent detail reproduction. And although its techy design is better suited to a desk than a TV stand, build quality is extremely robust and the inclusion of a control console is a convenient feature, despite its slightly cryptic quirks. There’s also a useful range of sockets, although the lack of HDMI inputs and Dolby True HD/DTS HD MA decoding is a slight disappointment and undermines the Z906’s status as a cutting-edge home entertainment hub.

Sound quality compared to previous model, Z5500?


May 25, 2011, 5:15 pm

Exactly, I completely agree with stranded. Why isn't the system put into context with some competing products and its previous generation? These might just as well be the same thing with a face lift. The Z5500 seem a bit more stylish and living room friendlier to me though.

But if I use PowerDVD 14 through analog inputs, I can have decoded DTS-HD and Dolby Digital HD... right?


December 10, 2014, 3:35 pm

Is there any new model coming up in this range ?


August 25, 2015, 8:06 am

I don't know whether Powerdvd could support Dolby Digital HD since I never used it before. Macgo could support this format.

I just wanted to wade into this review because I've now got both units side by side. The Masterpiece but poorly manufactured Z5500's and the new Z906 Logitech speaker sets. Sadly the downsizing of the subwoofer cabinet and subwoofer itself does it no favours.

The ZX5500's subwoofer reaches noticeably lower frequencies and NEVER EVER distorted, she just kept soldiering on with some epic excursion and teef smashing bass to boot.

The Z906's in comparison? The bass isn't anywhere near as strong down low and the over-simplification of the controls is absolutely abysmal. Long gone are the days of having a beautifully weighted volume control knob which was both a joy to use and to spin to maximum whenever the moment took you.

On both units I used the Asus Xonar DSX pci-e sound card and an optical connection to the speakers, so be fair on them both, the sound production environment was kept the same by using the same songs at the same volume levels... speaking of levels - I miss 'Music' mode on the Z5500's.

My Z5500's died after nearly 8 years usage.
I can't see the Z906's hanging on as long sadly...

Just to add my thoughts on this...

I got a set of the Z906 a few months ago.
I have been using altec Lansing ADA995 setup for a good 10 years or so now and they are flawless, I just wanted to go Digital.
The Z906 are abysmal junk.
They are not even in the same league as the Altec Lansings.
The Logitech are back in the box.

I am not one bit impressed by them.

I have tried them on a handful of my PCs, using a few varations of SoundCard.

Creative Recon3D, Z and ZxR
Asus Strix, D2X and Essence

I have also tried Analog, Digital AUX and Digital Optical, in 2 and 5.1 Audio and, as I said... Unimpressed.
