Not all subwoofers are meant for pumping bass into concert venues. Our Spectra series studio monitors include the Spectra-12SUB and Spectra-10SUB. For casual listening or detailed studio work, these subs will bring all the detail of the low frequencies to the fore so you can enjoy it or shape it to your desire. Studio subwoofers from Seismic Audio are powered or active, giving you the convenience of a powered speaker in your recording studio.We also offer replacement studio subwoofer speakers that will fit any cabinet of the appropriate size.
