How stable is the load on the new RF-7 II? I am leaning toward the vertical bi amp configuration, however am still interested how my amps will behave bridged mono without sending them out for mod's. If I do go with bi amp do you think vertical is best? My intuition says so due to the fact that each speaker will be driven by the same amp. Therefore each amp will be able to utilize its power supply to accommodate both the high and low range of the speaker. In theory providing a bit more head room than horizontal bi amp configuration. Is this correct?
