Hidden Sound sets are made to order - we don't work with stocks. Each set is made uniquely for you and delivered in about 8 weeks after you order it - hand-made like a precious piece of art. Just decide which size of room you need covered. The smaller ECO is enough for up to 30 m2, which is a typical living room today, while the EVO easily covers double that size, up to 60 m2.
And if you need even more space covered with really good sound, ask for our special solutions featuring pairing of more units, maybe two ECOs or two EVOs or one EVO and one ECO, or even installing our third product - the completely invisible ARX speakers - in your ceilings or walls.
