Watching the loudspeaker industry struggling to cope with the demands of flatscreen television displays has been an unedifying sport. Yet this is outclassed by the even bigger compromises made by the manufacturers of the sets themselves, who seem to delight in throwing the baby out with the bath water by sacrificing any pretence of sound quality in the pursuit of ever thinner and smaller form factors. And don't even get me started on the unholy fiasco the industry has made of civilizing the subwoofer...

Well, here's a system designed to match the packaging advantages of a sub/sat array - and it's strikingly successful in the way it does so. Interestingly, it comes from MartinLogan, a loudspeaker manufacturer with an established track record of excellence, which it is patently not about to sacrifice on the alter of diminutive packaging.

So let's get it on record straightaway: as a sub/sat system (albeit one larger than the designation might normally infer), this Fresco i/Dynamo 5.1 system is in a class of its own. It has a tonal balance that's light and open, perhaps a little too forward if I was pushed, but undeniably detailed and analytical, with negligible levels of obvious colouration.

As a 5.1 system, MartinLogan's Fresco i/Dynamo is particularly impressive with the often unnoticed off-stage sounds - the subtle sounds of water lapping in Swimming Pool for example, and the way that the different surroundings modulate speech dialogue quality in the same film.

As so often, it is the more subtle and less in-your-face audio events where this system really struts its stuff, though to its credit it also packs real power in the action scenes of Ridley Scott's sonically excellent Black Hawk Down. I suspect you could run out of grunt when playing back this film too enthusiastically, butthe subtly nuanced stuff is, well, subtle and nuanced.

Speech quality is always crisp, intelligible and genuinely lifelike - someone has done some serious listening while developing this model - and the music and special effects that flesh out most soundtracks are well-defined and colourful, with justa hint of aggression at times.

The Fresco i, the all-purpose satellite speaker for this system, is somewhat of a departure for MartinLogan, which has reworked its favoured electrostatic flatpanel technology for a multichannel audience. Given its style and positioning flexibility, it's ideal for those who want to use their speakers with flatpanel monitors, but without the usual sonic tradeoffs.

The system reviewed here includes five identical satellite speakers (centre, front left/right, and rear left/right, though more could be added).

To augment the bass and create a full 5.1 speaker system, I added MartinLogan's Dynamo subwoofer . Any sub may be chosen from MartinLogan's range and the Dynamo is the smallest and most affordable,yet it is remarkably capable and its compact dimensions suit the Fresco i's stylish attributes down to the ground.

A bigger subwoofer (this one consumes little more than one cubic foot of space) will give a bigger bang, but unless treated sympatheticallyit will be at the expense of musical integrity, control and homogeneity.

As small subs go though, the Dynamo is rather exceptional. The team responsible for the voicing seem to share the same kind of sensibilitiesas those responsible for the brand's traditional electrostatics. I'd even be tempted to add another: more than one sub will enhance the evenness of the low-frequency output in larger rooms, and allow the system to play louder.
