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.
GoKawiil's interpretation of the reporting above, not reported fact.
The experiment suggests Ikea's cheap, chainable speakers can scale to surprising numbers with minimal hardware failures, hinting at an accessible route to large-scale audio setups without specialized equipment. However, the testers' comparison with the LG Xboom indicates that sheer speaker count cannot match purpose-built drivers and signal processing for sound quality, implying diminishing returns as more units are added, especially past 100 speakers where syncing reliability began to falter.
- 149 of 150 Ikea Kallsup speakers ($10 each) were successfully linked for a combined cost of $1,490.
- At high volumes the wall was extremely loud but lacked fidelity; at moderate volumes it performed more competently.
- Syncing reliability declined past 100 linked units, though no speaker failed to connect more than twice.
