Dynaudio is what I consider the best option for me in Hi-Fi, so much so that I've become one of the few dealers to sell their products online in the US. If you're looking for the best wall speaker you don't need to look any further than these. These will not fit in a standard depth wall as they require almost 4" of depth. Installation is pretty straightforward and the package includes a template for making your cuts. These feature a high quality 1" tweeter and either a 6.5" or 8" woofer.
