US brand EMP Tek was founded as recently as 2007, but was set up by audio boffins with over 30 years' experience, designing speakers for esteemed names such as ParaSound, McIntosh and JBL.

They've been brought to the UK by distributor Aldous Systems, which has set the ball rolling with the Impression series. Although this range includes four off-the-peg packages, this 7.1-channel system has been pieced together from the individual components.

Of course, it's a powered affair that packs a 100W amplifier and a 10-inch poly-matrix woofer, ready to unleash on your neighbours. There's a built-in limiter to stop it from bottoming out and a full buffet of controls on the back panel, including dials governing gain and crossover (ranging from 40 to 180Hz), line-level input and outputs, a switch that flips the phase 180˚ plus two sets of high-level springclip terminals.

They easily tease out gentle ambience and subtle effects, but when the ante is upped they can shoot loud effects towards your head with the same snap and vigour as the fronts.

When playing the 7.1-channel mix on Hellboy II: The Golden Army, the E5Bi surround backs hold their own next to these behemoths. It's a seamless rear soundfield, reproducing the 360˚ sweep of effects during the Troll Market scene with pleasing clarity and accuracy, beautifully shaping every little flutter and tinkle. I also tried the system with two sets of E5Bis at the back and, although you lose a little of that all-round richness, they still conjure up a wonderfully absorbing atmosphere.

There's also a lovely robustness to the midrange, which keeps Inception's verbose dialogue consistently audible throughout the quiet and the carnage.

Unplugging the sub, I soon discovered the value of those three woofers, too. In isolation they provide plenty of punch, which makes music sound wonderful in a straight stereo setup. It falls short of the absolute silkiness of the very best systems but for the money it's a sterling effort.

For movie listening the sub adds another dimension. Taut, potent and free from unwanted resonance, it fuses with the towers and injects healthy doses of deep bass. It doesn't have quite the same fearsome, foundation-shaking power as subs from some similarly priced systems (Teufel's THX Ultra 2-certified System 9 springs to mind) – but it's not far off.

Welcome to Blighty

So, all things considered, does EMP Tek deserve a place on the busy home cinema highway? Emphatically so. It makes a sensational UK debut with a system that's got the lot – power, dexterity, smoothness and exceptional clarity – all of which will leave a lasting Impression.
