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

I’m 5’6” and ordered the small — it fits perfectly! The color is exactly as shown in the pictures, a beautiful beige that goes with everything. The fabric is incredibly soft and comfortable, making it great for layering or wearing on its own. I’m really happy with this purchase and would definitely recommend it!

Nice but not great

Fits true to size. I ordered a small and it was a great fit. Could be a bit softer. Loved the style. Not too thin or not heavy, nice weight. This quality of the sweater was nice, however the buttons broke apart as I was styling the cardigan. Not happy to have to sew on small buttons to fit the small holes. It’s nice but I had to put too much effort into wearing it.
