When you first listen to the Acora Acoustics SRB loudspeaker, we humbly suggest you keep your eyes closed. The SRB delivers such a wide, tall and engaging soundstage, you may not believe the sound is coming from the diminutive SRB. You will hear nuance and depth to the music. We believe you will hear many things you simply hadn’t before. What you won’t hear is the enclosure. Acora Acoustics loudspeakers are constructed using hand-crafted, specially treated, natural granite enclosures. The rigidity of granite far exceeds that of traditional particle board or wood enclosures. One of the benefits of this is as the SRB’s drivers move to push air / create sound, the enclosure isn’t absorbing this energy and dulling or smearing the sound. The SRB also utilizes world-class drivers and a hand-built crossover network, however the real secret to the Acora Sound, is that you only hear these, not the enclosure.
