Waterfall Audio Serio 2.1 Review - Performance and Verdict Review


Avatar is our movie of choice for testing the Serio’s mettle, and its epic action scenes sound terrific. There’s an instantly gratifying crispness to the sound, with clear, well-controlled high frequencies. This makes the climactic battle between Jake and Quaritch in his clanking robo-suit sound sparky and dynamic, with real drive behind the punches and smashing tree branches.

We’re also impressed by the clarity of speech, and the way Serio handles loud sounds like screeching Thanators and gunshots without sounding excessively strained or harsh. It’s not the smoothest or refined set of speakers we’ve tested – with a single full-range driver on board it was never going to hit the sonic heights of proper floorstanders, and at times the sound is a little nasal – but it’s certainly good enough to make your TV hang its head in shame.

The subwoofer also does a stand-up job, reproducing low frequency sounds like explosions with satisfying depth and potency, although as we found when testing the Hurricane Evo system it’s not so great at eking out subtle ambient bass sounds during quieter moments. On the whole though, the Serio system delivers a crisp, feisty sound that inspires excitement, although it’s probably not potent or assured enough to completely justify that price tag.

We tried out some music and the Serio delivers a decent sound, with plenty of body in the midrange, sparkling high frequencies and deep, agile bass tones.


At just under £800, the Serio 2.1 system is aimed at those who crave cutting-edge style no matter the cost, and that’s something it has in spades. The satellites are cute and eye-catching, thanks mainly to the classy glass panel, compact dimensions and white finish. They’re ideal if you hate clutter, and they offer decent sound quality too, much better than most budget one-box 2.1 systems, although it’s worth bearing in mind that you can get much better performance from cheaper speakers – it all comes down to how much you like the thought of having glass speakers adorning your lounge.
