Product details

SB Acoustics Satori MW19PNW-8 7.5’’ White Egyptian Reed Cone Woofer

 

The Satori range was founded to separate more expensive projects from a wider range of more affordable – but still high-end – SB Acoustics products. “As we get more experience, new materials, better simulation tools, we believe in benefiting the customer with those improvements. We always knew that geometry is essential and we are working more and more with geometry. Every time we get new materials, like beryllium, and we optimize the designs, there’s always room for improvement. We’ve been able to implement significant improvements with beryllium, and we could obtain pretty good results in combination with geometry.”
