DLS Flatbox

Made in Sweden and now represented in the US by SimpliFi Audio, the DLS Flatbox on-wall loudspeakers come in five sizes (Mini, far right: $249 each; Midi, center: $349 each; Slim Large; Large; and XL, far left: $499 each), can be hung horizontally or vertically, and are available in variations of white and black cabinets and grilles. There are also three subwoofers, including the Flatsub8 ($799), used in the room. Partnered with Resolution Audio’s Opus 21 system and inexpensive DNM cables, the speakers threw a surprisingly wide stage, despite being mounted on temporary plywood walls. As we went up the line, I noted greater bass extension, but the Midi version seemed best balanced with the room and subwoofer.
