INTRODUCTION
Congratulations on your purchase of the Vector 212 Extension Guitar cabinet. You are now
the owner of the most innovative guitar speaker combo cabinet ever produced. The same
innovation and killer sound that you can find in our Vector Cabinet and Theta Head is now
combined into one package and is ready for low-end players and shredders of all kinds.
Years of experience in designing the highest performance Active Sound Reinforcement
cabinets has allowed ISP Technologies engineers to develop the ultimate guitar combo
extension cabinet. The Vector 212 was designed to provide the maximum possible over the
top performance with stunning low-end punch and definition. With 100 watts RMS
driving a single Celestion 12” speaker and 300 watts available to deliver the
thunderous low end, the Vector 212 really delivers the sound never before
