ctroys12 Posted November 16, 2011 Share Posted November 16, 2011 Thanks in advance for anyone who can help! My setup is as follows:2 RF-82 ii fronts, RC-62 ii center, Denon AVR-1912, PS3, Panasonic 65GT30, Subwoofer (yet to purchase, need advice. How much benefit will I get from bi-amping the RF-82 ii's? And is it difficult and worth the time? Are there any disadvantages, like poteential to blow a speaker? Here are specs on my Denon:Surround System Class 7.1 channel, Response Bandwidth 10 - 100000 Hz, Signal-To-Noise Ratio 100 dB, Input Impedance 47 KOhm,Input Sensitivity 200 mV ,Amplifier Output Details 90 Watt - 8 Ohm - 20 - 20000 Hz - THD 0.08 % - 7 channel(s) ( Surround ),125 Watt - 6 Ohm - THD 0.7 % - 7 channel(s) ( Surround) Also, does a powered subwoofer drain power from the Denon? Any suggestions between the SW-310 for $500 (reg $1050) 400W cont/900W peak vs. something smaller like a Velodyne Impact-12, $319, 165 Watt cont./275W peak? Are either grossly over or under powered for blending with my system?I've got vaulted ceilings and a lot of space to fill, but I am also in a townhouse...Thanks in advance.

R3bornlife Posted November 24, 2011 Share Posted November 24, 2011 Firstly, although I haven't bi-amped my speakers I would suggest going into your local home theater store, (not a best buy, etc) and get a good amp JUST TO TEST, do not buy it if they dont have a return policy. Hook it up and see for your self if you hear a major difference. If you don't think it's worth the money, return it. A powered subwoofer will NOT drain any power from your reciever. And I would suggest looking into one of the "id" subwoofer brands such as epik,hsu,svs, etc. Klipsch subs are known for being overpriced. I personally have all klipsch subs but thats only because i got them for VERY good prices. Go on craigslist/kijiji and look at used subs for a great deal too. that impact-12 is below your system, I reccommend a much better sub.

Matthews Posted November 24, 2011 Share Posted November 24, 2011 Welcome to the Forum, From my own experience, bi-amping my 7's has produced marked improvements. A taming of the horns if you will. Currently, I am running the drivers of my RF-7's with a 250 wpc Yamaha M-80, the 7's love power and this really sends the huge punch I was looking for. Before bi-amping the the horns were very bright and ear piercing. With the addition of a small Rotel 50 wpc amp to run the horns (bi-amped) this brightness was eliminated. I believe the RF-82 has similar characteristics and would benefit as well to such application. As far as your choice of subs, I originally was running 2 Velodyne Impact 12's. Note, you get what you pay for... The Impacts do their job but are certainly lacking in the "earth moving" department. I upgraded to the Paradigm PS-2200's. Ground shaking improvement. I would suggest you find as high quality and powerful sub as you can afford. The thoughts of the extra dollars will melt away after your first session I hope this at least gives you something to think about. I think the most important thing to remember is to just have fun with it. Again, welcome to the Forum and your new hobby. Quote Link to comment Share on other sites More sharing options...
Luxman Posted December 9, 2011 Share Posted December 9, 2011 Matt- Are you passive bi-amping and if so, how do you adjust the levels between the horn and the woofers? You can see my equipment listed below. I have tried everything to tame my RF-7s. I just spent $3,000 modifying my $, 1000 player and it sounds wonderful except the horns still hurt my ears. I would like to try my tube amp on the horns and my SS amp on the woofers but I need to find a way to balance the two because my outlaw is much hotter than the tube amp. I have to find a way to lower the SS amp. I really dont want another preamp in the chain if I can help it. Thanks for any advice! Quote Link to comment Share on other sites More sharing options...
Kev the ironworker Posted December 9, 2011 Share Posted December 9, 2011 Hi .... Just thought I'd add my 2 cents. I too have a pair of Rf-82's that i had hooked up to an Onkyo Ht-Rc 370. I bi-wired them and found a noticeable difference (positive)...seemed the highs and lows were "separated" and "clearer" sounding... I've since added a Yamaha m-85 amp and I'm now getting ready to move out of the house ! (wife, neighbors and the dog now hate me !) I'd try it, or at least try bi-wiring....

txinliner Posted December 22, 2011 Share Posted December 22, 2011 i to have noticed a diffrence in the sound of my rf62s when biwired.I know that is differnt from biamped but just the same there was truely an audable differance.I am using a marantz sr6005 with audioquest type 4 cable to the tweets and cheap monster cable to the woofers,cd is a marantz cd5003 with audioquest interconnects ,sounds fantastic.
