Bi amping RF-7II’s

Recommended Posts

Posted (edited)

So I have a Klipsch KDA-1000 4 Ch amp that I want to use to power a pair of RF-7II’s.

I will use two ch (500 watt) per speaker.

my ? Is ..

I’m trying to find out how are the speakers separated internally when I remove the binding posts.

I will be putting 1- 250 watt channel per binding post..(500 watts total).

basically, what’s the TOP post going too and what’s the BOTTOM post going too.

 

whats the crossover doing ????

 

thanks,

Bill

Give it awhile, you should have lots of responses by this evening. Lot of long time fans and owners of RF-7II here, and lots of crossover network knowledge on this.

Bottom posts go to the woofer(s) section of the crossover and top to the tweeter section. Removing the bars that shorts them together just removes the common connection between them that allows for using just one amp. The crossover is still in the circuit with the straps removed, just the high and low sections are now separated allowing the use of 2 amps or amp channels.

Thanks. That is what I thought.

my concern is.... Will the Tweeter handle 250 watts?

i know the speaker handles 1000 watts.

Not knowing for a fact, I would still say no. But I will say long before you reach that much power to the tweeters it will be so loud you can't stand it.

Not putting jumpers back on.?.?.? I’m thinking you did not understand/read my initial post.. but, thanks anyway....

 

I’m trying to feed the RF-7II’s with more than 250 watts per channel. Speakers are 1000 watts ea.

My KDA-1000 amps are 4 channel (250x4) non bridgeable........

this is why I’m REMOVING straps and BI AMPING.

 

I might just pull crossover and see how it’s wired.

I tried contacting Klipsch 4X’s, but the Arse farts don’t answer and I’m out on Tele prompted  HOLD for over 40 min each time.. 

Also put in 4 call/email  back requests.

NEVER answered....

HORRIBLE Customer/Tech service..

 

I have over $15,000 in Klipsch products for my theater  and I can’t get a simple answer from them.....

 

Thats why I’m on here ... and still at square 1...

 

To all ..... Thanks for your input.

Why do you need/want that much power going to them?  {EDIT: They are rated by Klipsch  at 102 dB@ 2.83v/1 meter.}

Speakers are 250 RMS each.  1000w peak doesn't mean that they'll handle 1000 watt amp for any length of time or even 500.

I mainly want the front to have more power while listening to music. 500 watts per speaker.

 

I’m putting 250 watts per ch to the remaining 13 speakers.

You need to learn the difference between RMS and Peak ratings before you go any further.

 

Maybe if you explained why you need 500 watts/speaker we would better understand what you're trying to accomplish.

The question I feel you need to ask yourself is "how loud SPLwise do you want to listen?"and work backwards from there. You may be surprised how little power you need to get the dB you want.

EXCUSE ME BRO... You need to learn some people skills. IMO.... You sound a little

arrogant and cocky over that KEYBOARD....

Terminology and understanding  complex audio are not the issue.... BRO

 

I quite clearly stated that I did not SEE the 250 rms.. not that I did not understand it. WTF ???

 

Do me a favor Bro... Please stay out of conversation..

 

have a a great day
