I have the f12se and have run them with Acoustat Monitor 3's and with a pair of Magnapan 1.7's that my son owns.. beefy amp.. fast and quick, might depend somewhat on what loudspeaker you are partnering with?
crossover point, etc.. but is a more expensive model so it should be a superior product. It was right after that I saw a newer model with two 8's which you could crossover at a higher freq. I wonder how that model does?
