Guess you should have researched what you are buying. Are you saying you don't want it to crossover with speaker and just want it to add bass only. Yea its meant to be crossover bass with a speaker its paired to. Send it back if its not what you want but no need to be upset because it functions as intended.
If you want just a zone bass only no crossover with other speakers your best bet is a Sonos Connect hooked to a standard wired subwoofer.
