Rippyman Posted January 2, 2012 Share Posted January 2, 2012 Has anyone Bi-Amped their RF-7 II's? If so, how were the results? I'm considering the Emotiva XPA-5 and Bi-Amping my two fronts and using the 5th channel to power my center. Quote Link to comment Share on other sites More sharing options...
Zen Traveler Posted January 2, 2012 Share Posted January 2, 2012 There has been quite a bit of discussion on this and here is a search link from this forum: http://community.klipsch.com/search/SearchResults.aspx?q=%22rf-7%22+bi-amp&o=Relevance Quote Link to comment Share on other sites More sharing options...
Rippyman Posted January 3, 2012 Author Share Posted January 3, 2012 Hmmm, so basically from this blog, it sounds like passive bi-amping which I would be doing is just a big waste of money. No benefit. Full blog here. http://community.klipsch.com/blogs/andyw/archive/2007/09/07/bi-amplifying-or-bi-amping.aspx So where’s the controversy? Just taking two stereo amplifiers and hooking them up to your speakers (removing the straps on the input terminals) is called passive bi-amping (or “fool’s bi-amping” for the non-PC) and is very close to being just a waste of money (again many people will disagree). You are sending the entire music signal to both amplifiers and both amplifiers are amplifying the entire signal, but you are allowing the passive crossover network to filter the amplified signals. I can’t think of any benefit in doing this. The tweeter amplifier is still reproducing the bass signals and they are still causing the amplifier to clip. (Perhaps there is a slight benefit by not requiring the current of the bass notes, as this can increase the headroom of the tweeter amplifier – by not drawing down the power supply rail voltage.)

Zen Traveler Posted January 3, 2012 Share Posted January 3, 2012 Yep. That's the conclusion I came up with as well. Quote Link to comment Share on other sites More sharing options...
stormin Posted January 3, 2012 Share Posted January 3, 2012 Tube amp on the horns and high powered SS on the woofers is not a waste of time or money when it comes to high efficiency Klipsch. Especially when most of the woofers have such low impedance dips. Quote Link to comment Share on other sites More sharing options...

Dennie Posted January 3, 2012 Share Posted January 3, 2012 SS stands for Solid State. The Sweet beautiful sound of Tubes (low power) on the Highs and SS (high power) on the Low end/Bass is a better way to "Bi-amp" your speakers. The Tweeter/midrange does not require as much power to reproduce these frequencies, but when you want to reproduce 30hz at 100db, it is going to take some POWER! So, a lot of people use this method to "bi-amp" their speakers. Dennie Quote Link to comment Share on other sites More sharing options...
