Hi, I have the Infinity RS1a four tower speakers that I have bought for a long time. I never hook them up as I do not have the amplifiers. Now that I have the space to use these speakers I plan to buy used amplifiers to run the bass towers and mids towers. After reading the manual it seems that I can use mono amps for the mid tower with no problem. Based on my research with forums I found that I should not use mono amp for the bass tower because there are bridged amp. But at the same time there are people who have used mono amps for the bass tower. So I am confuse. I have the standard crossover box. Would I be able to use monos amp like Odyssey monos or Threshold SA-1 to drive the bass tower? I plan to use tube amp for the mids tower like one Mcintosh M275 amp. Thank you in advance for your assistance.
