The McIntosh RS100 is a powered tabletop speaker designed with classic McIntosh styling, incorporating DTS Play-Fi wireless technology for streaming music. It features a rectangular design measuring 12.75 inches tall and 8.25 inches wide, finished in high-gloss black wood and supported by a brushed-aluminum base. Weighing 15 pounds, the RS100 is constructed for durability and aesthetic appeal, reflecting McIntosh's commitment to quality. The speaker includes a 4-inch polypropylene woofer and a 0.75-inch titanium dome tweeter, delivering 60 watts of power and a frequency response rated down to 55 hertz. It utilizes a mono configuration but can be paired with another RS100 for stereo sound. The rear panel provides an aux input and a subwoofer output, while setup and control are conducted via the Play-Fi app, which allows streaming from various services. Despite some criticisms regarding its setup process and certain sound qualities when using the front grille, the RS100 is praised for its excellent sound quality and distinctive visual design, offering a blend of modern functionality with traditional McIntosh craftsmanship.
