The primary differences between the Pill 2.0 Speaker and the Pill XL Speaker are size and loudness. The XL is nearly twice as big as the 2.0. The 2.0 is 7.5" (19 cm) long by 1.8" (4.5 cm) wide, while the XL is 13.3" (33.8 cm) long by 4.1" (10.4 cm) wide. Being much larger, the XL is also much louder, with greater output power.
