More about these cheaper Acora QRC-1 Quartz Speakers

The Acora cabinets are made from gabbro, not granite. Granite has quartz grains in it. Gabbro does not, and it is the coarse grained equivalent of basalt, where granite is the coarse grained equivalent of rhyolite. Granite has about 70% SiO2 in it by weight, whereas gabbro has about 50% SiO2 by weight. It is also substantially denser than granite, and has a higher sonic velocity. Gabbro is dark colored, and granite is light colored and typically has mica (biotite or Muscovite) in it. I would expect the denser gabbro to make a better sounding cabinet.

 I’m a Berkeley Geology PhD, and a former research scientist, Professor, and Geology Department Chair who has worked on a variety of basalts and gabbros  in my career.

 Please forgive the beating of my chest to establish credibility, but I do like the sound of the Acoras. 

Happy to see my Sasha DAWs are on the list. I saw and heard the Acora speakers last year at Axpona. They sound great. I can still recall their amazing bass inside that giant sized show room. The Acoras were one of my top two favorite speakers at the show last year. The other speaker was a three way horn type driven by an SET amp and a Lampizator DAC. Couldn’t pull myself away.

First glance at the Acora speakers in this large room at Axpona my thought was this room will be uninteresting. These diminutive speakers looked swallowed up by the room. Then the music started and I was captivated. They energized that large room with ease. Looking at their size and hearing the music they were making was baffling. They defied my ingrained expectations based on decades of experiences.

Btw- Acora’s website says the cabinets are made from granite. Maybe they say granite because it is a more commonly recognized word.

"Buyers Guide"?

They could have just printed a sign: "Exit" so 99% of buyers that by accident or misguided ventured 'in' there can get the hell out quickly.

Before they collapse in a laughing attack from seeing people actually spending such nutty amounts on equipment (a whole INDUSTRY is milking those fools). 

No Rockport speakers in this buyers guide?! Blasphemous !
