havingitall Posted February 17, 2006 Share Posted February 17, 2006 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. Quote Link to comment Share on other sites More sharing options...

IB Slammin Posted February 17, 2006 Share Posted February 17, 2006 Hasall, Welcome to the palace of loons. Don't worry about hammering the 7's. They will handle more power than I can stand to listen to them without DeanG crossovers. I have been known to run up the volume on bast*rd Cornwalls at times. My comment is not about large SPL's, but about quality. Check him out. His RF-7 filter mods are worth every penny.[] Terry Quote Link to comment Share on other sites More sharing options...
MrMcGoo Posted February 17, 2006 Share Posted February 17, 2006 The RF-7s will take all the clean power you give them; your ears are likely to give out first. Just do not do anything silly with the volume control and you will be fine. See my profile for my Sunfire gear. Bill Quote Link to comment Share on other sites More sharing options...
3dzapper Posted February 17, 2006 Share Posted February 17, 2006 "How much will RF7s take?" The question is " How much can you take?" I've had my Khorns up to 128Db. They could take more, I couldn't!!! Rick Quote Link to comment Share on other sites More sharing options...
jheis Posted February 17, 2006 Share Posted February 17, 2006 ...voltage output going to the LF and the current output to the HF... Huh? Quote Link to comment Share on other sites More sharing options...

Huh? _______________________________________ I don't know much about this but I have been reading about Nelson Pass Current Source Amps recently (as opposed to voltage source). Maybe someone here can sum it up in a nutshell. I forget teh technical difference. Chris Quote Link to comment Share on other sites More sharing options...
MrMcGoo Posted February 18, 2006 Share Posted February 18, 2006 Sunfire amps have a 1 ohm resistor in series on the current source outputs for the front channels. The voltage source outputs for the same channel have no resistor in series. Bob Carver recommends that the high frequency driver(s) be hooked up to the current source and the low frequency driver be hooked up to the voltage source for best results. The manuals for the Sunfire amps explain it all. The manuals are available on the Sunfire site. Bill Quote Link to comment Share on other sites More sharing options...
mike Belgium Posted February 18, 2006 Share Posted February 18, 2006 I prefer the voltage output aswell for the tweeters. the highs are a bit to soft with the current output and voices are not so lifelike. Quote Link to comment Share on other sites More sharing options...
havingitall Posted February 18, 2006 Author Share Posted February 18, 2006 I tried that as well and with 4 RF7s and 1 RC7 all loaded with Horns it was just a bit crisp in here. I have also found that sound tracks in movies are in fact more lifelike with the current feed to the HF.I guess sound really is in the ears of the listener.

Duke Spinner Posted February 18, 2006 Share Posted February 18, 2006 ...voltage output going to the LF and the current output to the HF... Huh? they just take the output off a resistor........ knda like the Magnetic Field amps .... Marketing Quote Link to comment Share on other sites More sharing options...

michael hurd Posted December 2, 2007 Share Posted December 2, 2007 RF7's are very robust, I have the RF3II, and have dumped 550 wpc ( clip lights coming on ! ) and hurt a tweeter after about a half hour. ( found out the treble boosted itself in the AVR settings ) This was with music of a dynamic nature. The average power levels were around 5 wpc, with short term peaks exceeding 550 wpc.

felitopaz Posted December 5, 2007 Share Posted December 5, 2007 My RF-7's are bi-amped using Sunfire Cinema Grand 5x200 to the woofers and Aragon 8002 to the tweeters and they sound sweet. Quote Link to comment Share on other sites More sharing options...
