I'm thinking of using a f3 as a part of a tri-amp setup for my 3-way active speakers. I originally thought of using it on the highs where it should be more than enough driving scanspeak 9900 tweeters. After talking to some people, I think it may be more suited for the midrange though. My speakers have 2 seas 7" excel drivers (w18e001) per side (total of 4) and each driver is 8 ohms, 86.5 db efficient. Would this be too much of a load for the f3? thanks in advance for your input.
