The passive Spectral speakers BRP and VRP are optimally matched to Spectral furniture and the Sonos Amp. The volume of the furniture is fully exploited to achieve the best sound. Due to its compact design, a soundbar has a much smaller volume and cannot perform at the level of a classic speaker, especially when it comes to music and bass reproduction. The Sonos Amp is a powerful amplifier, in combination with the Spectral BRP1 or VRP1 you get an excellent sound system and is fully compatible with all other Sonos solutions.
