The next level replacement for the discontinued MACH ONE. In the early eighties Radio Shack offered up the MACH TWO 160 watt Three Way Liquid Cooled Speaker System

Speaker Complement : 15"(38.1 cm) high-compliance woofer, 5"(12.7 cm) midrange (ferrofluid cooled), Advanced design dual radial super horn tweeter w/ultra-wide frequency range(ferrofluid cooled).
Enclosure : Tuned port design for extended bass response,removable grille.

Another great SS Rock speaker that was underestimated and overlooked IMHO.

but could be had for a song at half price during Radio Shack's once a year half off sellathon!
Years later they were re-badged as 'Optimus' MACH TWO,then sadly were quickly discontinued.Radio Shack has never come close to this type of speaker since.
