Mackie MRS10 10" Active Channel Studio Subwoofer 120 W Laptop/Desktop Speaker  (Black, Mono Channel)

Designed to add the perfect amount of dynamic, accurate low-end, the MRS10 10” subwoofer will enhance the listening experience in your studio without artificially adding boomy bass to your mix. Optimizing features include an adjustable Crossover to dial in the right amount of low end for your studio plus a polarity switch to make sure your mix is always in phase. With foot-switchable bypass functionality, MRS10 can be muted while returning your monitors to full range at the push of a button. When your mix has some serious low end that needs to be heard, look no further than the MRS10.
