System Audio Legend 7.2 Silverback

There is a limbo-land, somewhere between traditional audiophilia and custom install’s convenient disappearing act where on-wall speakers live in quiet solitude.

They might be a pragmatic solution to a paucity of floorspace, but uncharted depths of desire or a runaway pulse rate aren’t common side effects.

That might be about to change with this active wireless speaker – essentially a wall-friendly and more muscular three-way version of the Legend 5.2 Silverback standmount (HFC 474). Partly it’s because there’s so little to it: two Power DAC/ DSP-equipped active speakers, a pair of mains cables and a stereo wireless WiSa control hub.

The Legend 7.2 Silverback uses twin long-throw 140mm main drivers – one mid/bass and one bass – separated by a 25mm soft dome tweeter acting as the centre point axis, allowing the speaker to be sited vertically or horizontally. Each driver has its own combined Class D amp/DAC (from Texas Instruments) delivering a total of 225W a side.

As well as performing crossover duties, DSP is used to smooth the amplitude and phase characteristics, extend bass response and adjust dynamic equalisation so that the bass doesn’t fade at low listening levels.
