After reading all the past posts on the subject, I am still not sure on which is the best way to run my QSC RMX 1850. I have a Avatar B115H @ 8 ohms and a Avatar B210 @ 8 ohms. What are the advantages and liabilities to running them stereo (one cab per channel) or bridged mono (2 cabs in parallel = 4 ohm load)? I am asking the collective for practical advice. I already have cabling for both configurations. Thanks A.A.
