GoKawiilWIRED Links 149 Ikea Kallsup Speakers into a $1,490 Sound Wall
WIRED testers chained 149 of Ikea's $10 Kallsup Bluetooth speakers together to build a wall of sound, successfully syncing wireless playback across nearly all units at a total cost of $1,490. Only one of 150 speakers arrived broken, and the group compared the makeshift wall's output against the $500 LG Xboom Stage 501, a speaker WIRED rates as its top party pick.
