Glass loudspeaker expert Waterfall Audio has launched a discrete new version of its distinctive see-through speakers. The SERIO is a 5.1 system with five diminutive satellite speakers, though instead of Waterfall’s trademark glass cabinets the speakers have glass fronts only with aluminium casings.

The SERIO comes with three mounting options: on-wall, tabletop and standmount and is available in three main body colours: black, white and silver with matching grilles (orange and green ‘fashion’ grilles are also available).

Waterfall has incorporated its patented Heatstream technology into the design, which couples the speaker’s voice coil to the unit’s aluminium body, so the speaker’s Atohm drive unit can dissipate more heat and so offer greater than usual power handling for such a small speaker (125 x 125×85mm). The satellites are joined by Waterfall’s HF1 (High Force 1) active subwoofer, which boasts 150 watts of amplification delivered through a 9in bass driver.

The Waterfall SERIO is available now for £1,449.
