I have 4 RF7s and 1 RC7 all powered by a Sunfire Cinema Grand Signature Amp (405X5). The front three are biwired with the voltage output going to the LF and the current output to the HF. The sound is outstanding. However the RF7s are rated at 250 RMS with 1000 Watt Peaks. I would like to know if anyone has experience with the power handling abilities of the RF7s. I watch a lot of movies and love my music as well. I just installed the Sunfire CGS two days ago. I'm trying to get an idea how far I can go before blowing them up. I do not have to worry about clipping from the amplifier. All wires are 10 guage. Preamp is the Sunfire Theater Grand II. I have taken them up a bit already and I have heard no signs of stressing or distorting. Your thoughts please.
