Four years ago, I reviewed the Acora Acoustics SRC-1, a two-way floorstander that was one of the Canadian loudspeaker-manufacturer’s first three products. Acora is a relative newcomer to the high-end industry, launching in 2018, but the company’s profile has been high from nearly the beginning, in large part because of the attention-grabbing granite enclosures of its transducers. For more than half a century, Acora founder Valerio Cora’s family business in Toronto has been “dimension stone”—natural rock or stone that’s cut to a specific size and shape. Cora is an IT specialist and lifelong audiophile who had long wanted to build a speaker with a cabinet made of stone.
