Avantgarde Acoustic Duo SDThe Duo SD takes the Uno SD recipe (detailed elsewhere) and scales it up, both physically and also technologically. In comparison the Duo features a larger mid range horn which means it can work down to even lower frequencies and therefore reduce the crossover point to the bass system. The driver is larger too, up from 5" to 7" and an Alnico magnet is used, which are rightly prized for their improved texture, speed, reduced grain and more natural

Best paper plates I've bought in years. I hope Amazon sticks with this supplier!.
Size: 200 Count (Pack of 1)
These paper plates were marked South Korea. They are strong, that don't stick together, the price is right. Love them, just hope the same kind are delivered with this order! We'll find out soon.
